1. Animal disease ecology and transmission involves the study of how diseases spread between animals and their environments. Key concepts include reservoirs, where pathogens live and multiply; ports of exit, how pathogens leave an infected host; and modes of transmission, how pathogens are passed between hosts.
2. Many factors can influence disease emergence and spread, including climate change, land use changes, increased animal densities, and globalization. Climate change can alter disease patterns by changing temperatures and rainfall in ways that increase vector populations. Changes in land use and encroachment on animal habitats can increase contact between wildlife and livestock.
3. Integrated policies are needed to address socioeconomic, institutional, and production factors that influence disease risks at the

A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism.
Producers have a vested interest to keep their animals healthy
Bio-security measures in poultry production involve conceptual, structural, and operational biosecurity. Conceptual biosecurity involves isolating farms away from other poultry and major roadways. Structural biosecurity includes fencing, testing water sources, and separating live bird and storage areas. Operational biosecurity focuses on controlling access of people, vehicles, pests and preventing cross-contamination through various hygienic practices like footbaths, changing clothes, and disinfecting equipment between farms. Proper vaccination, disease monitoring and all-in/all-out production systems also contribute to disease prevention on poultry farms.

Malignant catarrhal fever (MCF) is an infectious systemic disease that presents as a variable complex of lesions affecting mainly ruminants and rarely swine. It is principally a disease of domestic cattle, water buffalo, Bali cattle (banteng), American bison, and deer. In addition to these farmed animals, MCF has been described in a variety of captive ruminants in mixed zoologic collections.MCF results from infection by one of several members of a group of closely related ruminant gammaherpesviruses of the Rhadinovirus genus.
Listeriosis is an infectious disease of sheep characterized by encephalitis and sometimes abortion in pregnant ewes. It is caused by the bacteria Listeria monocytogenes, a gram-positive, motile rod that is commonly transmitted by ingesting contaminated food or water, especially silage. Clinical signs in sheep include nervous system issues like circling, head tilt, and blindness, as well as abortion and septicemia. Post-mortem examination typically shows meningitis and lesions on the brain and organs. The disease can be diagnosed by isolating and identifying the bacteria, inoculating rabbits, serology testing, or ruling out other conditions. Vaccination with a formalized bacterin can help control listeriosis in sheep flocks
This document discusses various animal diseases including bacterial, viral, parasitic, and non-infectious diseases. It describes how diseases are spread, the body's immune response to fight off pathogens, and methods to prevent disease such as vaccination, quarantine, and selective breeding practices. Key points covered include the types of bacteria and viruses that cause illness, how antibodies are produced during active and passive immunity, pioneers in vaccine development like Edward Jenner and Louis Pasteur, and common diseases stemming from nutritional deficiencies or toxins.
Trichomonas is a protozoan parasite that infects the reproductive tract of cattle. It is transmitted during mating and causes early abortion in cows within 16 weeks of fertilization. Bulls serve as carriers and can transmit the parasite via semen even when frozen. Diagnosis involves microscopic examination of vaginal or preputial samples to identify the pear-shaped trophozoite stage that has 3 anterior flagella and 1 trailing flagellum. Treatment involves removing infected bulls from the herd and using artificial insemination to control spread.
Bovine Viral Diarrhea Virus (BVDV) causes two clinically distinct diseases: Bovine Viral Diarrhea (BVD), seen predominantly in cattle aged 6-18 months as a primary infection, and Mucosal Disease (MD), a sporadic and fatal disease that occurs in persistently infected (PI) cattle. BVDV is transmitted from PI cattle that continuously shed large amounts of virus. Infection can cause reproductive losses, congenital defects, and respiratory/gastrointestinal disease. Diagnosis is done through virus isolation, antigen detection, PCR, and serology of paired samples. There is no treatment for BVDV infection.
Fowl cholera is a contagious bacterial disease affecting domestic and wild birds worldwide, caused by Pasteurella multocida type A. It occurs sporadically or endemically in most countries. Clinical signs vary depending on the course of disease but commonly include fever, loss of appetite, respiratory difficulty, and hemorrhages. Post-mortem lesions show vascular disturbances like congestion and hemorrhages. Diagnosis requires isolating P. multocida from infected birds. Treatment involves antibiotics but does not eliminate the bacteria, so prevention focuses on sanitation, biosecurity, and vaccination.
Blue tongue disease in sheep and goatsNirmal Kumar
Blue tongue is a viral disease that affects sheep and goats. It is transmitted by biting midges and causes fever, facial swelling, and a blue discoloration of the tongue. Mortality can be as high as 50% in infected animals. Clinical signs include swollen feet and lameness. There is no specific treatment, so supportive care is given and vectors are controlled through insecticides and confinement of animals. Vaccination and movement restrictions are used to prevent the spread of the disease.
Blackleg is an acute, fatal bacterial disease that mainly affects cattle and buffaloes between 6 months and 2 years old. It is caused by Clostridium chauvoei bacteria found in soil. The bacteria enter through the gastrointestinal tract and spread to muscles, causing dark swollen muscles particularly in the legs. Clinical signs include fever, lameness, muscle swelling and pain, difficulty breathing, and loss of appetite. The disease progresses rapidly and animals often die suddenly within 2-3 days. Vaccination is the main prevention method.
The document discusses biosecurity measures for poultry production. It defines biosecurity, lists its objectives of preventing disease entry and spread, and describes benefits like reduced costs and improved health.

Climate change &animal health By Dr. V.K.GUPTA, Senior Scientist, Divisi...Dr Vinod Gupta
Climate change is caused by human emissions of greenhouse gases like carbon dioxide and methane. This document discusses the impacts of climate change on animal health and livestock production. As temperatures rise due to climate change, animals experience heat stress, which decreases their growth, milk production, and reproductive performance. Climate change also alters the spread of diseases by affecting vectors like mosquitoes and ticks that transmit diseases to animals. Changes in climate patterns can decrease food security and water availability for animals. Combating climate change will require global cooperation to reduce greenhouse gas emissions as well as local efforts to help animals adapt through improved management practices.
BEF is an acute viral disease of cattle and water buffalo caused by the BEF virus, an RNA virus from the Rhabdoviridae family. It is transmitted by several species of biting midges and mosquitoes. Clinical signs include biphasic or polyphasic fever, depression, stiffness, and lameness. Affected animals typically recover rapidly within a few days, though relapses can occur. Treatment focuses on rest and anti-inflammatory drugs.

Disease ecology is the study of interactions between pathogens, hosts, and their environment. It is an interdisciplinary field that combines epidemiology, ecology, and other disciplines to better understand how environmental changes can impact disease transmission and emergence. The challenges include predicting how human alteration of landscapes might lead to new diseases spreading from wildlife to humans, and developing surveillance methods to detect diseases early. Understanding disease ecology is important for preventing changes in pathogen virulence and managing diseases at the population level.
Animal disease ecology and transmission by Dr. C DomingoPerez Eric
The document discusses animal disease ecology and transmission. It defines key terms like infection, disease, ecology, and transmission. It then discusses how environmental conditions, animal hosts, vectors, and pathogens interact to lead to disease transmission. Specifically, it explores how factors like climate change, land use changes, intensive farming practices, and globalization can influence disease emergence and spread among animal populations.
Infection occurs when a microbe lodges and multiplies in the tissues of a host. Ranges of relationships between microbes and hosts include saprophytes, parasites, and commensals. Several factors predispose to microbial pathogenicity, including adhesion, invasiveness, and toxigenicity. Infections can be classified as acute or chronic, primary or secondary, localized or systemic, and clinical or subclinical. Six links must be present for an infection to spread: a portal of entry, a susceptible host, a causative agent, a reservoir, a portal of exit, and a mode of transmission. Microbes can be transmitted through various methods including direct or indirect contact, inhalation, ingestion

Trypanosomiasis is a vector-borne parasitic disease caused by Trypanosoma parasites. There are two main forms: African trypanosomiasis (sleeping sickness) transmitted by tsetse flies, and American trypanosomiasis (Chagas disease) transmitted by triatomine bugs. African trypanosomiasis is found in central and west Africa and causes a slow progression of symptoms, while American trypanosomiasis is found in Latin America and causes an initial acute phase followed by a chronic phase in some patients. Both forms require treatment with drugs to eliminate the parasites from the body.
The document discusses the history and development of kidney transplantation, noting that while the first successful kidney transplants occurred in the 1950s, significant advancements in tissue typing, immunosuppression, and surgical techniques were required throughout the following decades to allow kidney transplantation to become safer and more routine. It outlines major milestones and medical discoveries that helped overcome barriers to transplantation, such as the first successful transplant between twins in 1954 and developments in dialysis, immunosuppression drugs, and organ preservation techniques.
African trypanosomiasis, also known as sleeping sickness, is caused by microscopic parasites of the species Trypanosoma brucei which is transmitted by the tsetse fly found in rural Africa. The disease has been a serious public health problem in some regions of sub-Saharan Africa. Symptoms in advanced stages include alteration of biological clocks, confusion, slurred speech, seizures and difficulty walking or talking which can lead to death if not treated. Treatment options include drugs like diminazene and suramin, while prevention focuses on reducing reservoirs of infection and the presence of tsetse flies through screening programs and early diagnosis.
This is the presentation on Trypanosomiasis that covers classification and diseases caused by Trypanosoma, its life cycle, Geographical distribution, Transmission, diagnosis and treatment and finally its scenario in India.

The document discusses the ecosystem approaches to human health research framework. It provides two case examples of emerging infectious diseases - Nipah virus and H5N1 avian influenza - to illustrate how this framework works. For both cases, a transdisciplinary investigation considered social, ecological, economic, and behavioral factors and their interactions. This led to insights into disease emergence and spread. The research then influenced policies to regulate industries, improve sanitation, and stem wildlife trade - protecting both human and animal health.
This document discusses global health security threats from biological sources. It outlines emerging infectious diseases, antimicrobial resistance, and other biological dangers such as bioterrorism and dual-use research. Emerging diseases are spreading more rapidly due to factors like population growth, travel, and climate change. Antimicrobial resistance has risen dangerously as misuse of antibiotics grows. Strong detection, prevention and response are needed worldwide to address biological threats that ignore borders. International cooperation is essential for global health security.

a) PEST: A destructive insect or other animal that attacks crops, food,livestocks, etc. The term
pest may be used to refer specifically to harmful animals but is also often taken to mean all
harmful organisms including weeds, plant pathogenic fungi and viruses.
b) LIVESTOCK: Livestock are domesticated animals raised in an agricultural setting to produce
commodities such as food, fiber, and labor. The term is often used to refer solely to those raised
for food, and sometimes only farmed ruminants, such as chicken, cattle and goats.
C) SYMPOTOMS, DISEASES and DAMAGE:
Agricultural and domesticated animals are attacked by mites and ticks, insects, and animal
predators. These pests affect animal productivity by:
Livestock disease management is made up of two key components:
1) Prevention (biosecurity) measures in susceptible herds
2) Control measures taken once infection occurs.
The probability of infection from a given disease depends on existing farm practices (prevention)
as well as the prevalence rate in host populations in the relevant area. As the prevalence in the
area increases, the probability of infection increases.
Prevention Measures:
Preventing diseases entering and spreading in livestock populations is the most efficient and
cost-effective way of managing disease (Wobeser, 2002). While many approaches to
management are disease specific, improved regulation of movements of livestock can provide
broader protection. A standard disease prevention programme that can apply in all contexts does
not exist. But there are some basic principles that should always be observed. The following
practices aid in disease prevention:
d) SURVEILLANCE, CONTROL MEASURES and DIAGNOSIS:
Disease surveillance allows the identification of new infections and changes to existing ones.
This involves disease reporting and specimen submission by livestock owners, village veterinary
staff, district and provincial veterinary officers. The method used to combat a disease outbreak
depends on the severity of the outbreak. In the event of a disease outbreak the precise location of
all livestock is essential for effective measures to control and eradicate contagious viruses.
Restrictions on animal movements may be required as well as quarantine and, in extreme cases,
slaughter.
The major impacts of climate change on livestock diseases have been on diseases that are vector-
borne. Increasing temperatures have supported the expansion of vector populations into cooler
areas. Such cooler areas can be either higher altitude systems (for example, livestock tick-borne
diseases) or more temperate zones (for example, the outbreak of bluetongue disease in northern
Europe). Changes in rainfall pattern can also influence an expansion of vectors during wetter
years and can lead to large outbreaks. Climate changes could also influence disease distribution
indirectly through changes in the distribution of livestock. Improving livestock disease control is
therefore an effective technolog.
A Review on the Concept (Challenges and Opportunities) of One Health Approach...BRNSSPublicationHubI
This document discusses the challenges and opportunities of a One Health approach to controlling emerging and re-emerging zoonotic diseases. It outlines that zoonotic diseases are infectious diseases transmitted between animals and humans. While the One Health approach promotes cross-sectoral collaboration, challenges include difficulties in collaborative work across disciplines due to differences in approaches and a lack of standardized frameworks. Socio-political challenges also exist from public beliefs and rights issues. Ethical concerns regarding secure data distribution and wildlife management further impact One Health implementation. However, solving these challenges could make One Health a powerful tool for disease protection globally.
This document discusses emerging and re-emerging infectious diseases. It begins with trends in infectious diseases, then defines emerging and re-emerging diseases. Factors that contribute to emergence include changes in the agent, host, and environment. Examples are provided of diseases that have emerged or re-emerged recently, including SARS, avian influenza, hepatitis C, and antibiotic resistance. The response from public health is also mentioned.
BACTERIOPHAGE THERAPY IN AQUACULTURE – FRIEND OR FOEAusPhage
This document discusses the potential for using bacteriophages (phages) as an alternative to antibiotics in aquaculture to control pathogenic bacteria. Phages are viruses that infect and kill specific bacteria. They have been used therapeutically in Eastern Europe for over 60 years with proven success. The growth of aquaculture is limited by infectious disease outbreaks caused by bacteria like Vibrio and Aeromonas. While vaccines and management practices have helped, antibiotic resistance is a major concern. Phages offer a natural solution as they can target antibiotic-resistant bacteria and replicate at the infection site. The document reviews phage biology and therapy approaches, noting that virulent phages are best for killing pathogens without transferring genes. It compares advantages
Ecology and Pest Management discusses the importance of understanding pest populations and the factors that influence them for effective integrated pest management (IPM). Key points:
- Biotic and abiotic factors like temperature, humidity, food availability, and natural enemies influence pest population levels. Monitoring these factors is important for predicting population changes.
- IPM utilizes cultural, mechanical, physical, biological and chemical control methods, with the goal of preventing economic damage while minimizing risks to the environment.
- Pest surveillance and forecasting through monitoring and data collection over time allows for timely control responses before populations reach economic injury levels. Understanding a pest's ecology is essential for IPM.
Ecology and Pest Management discusses the importance of understanding a pest population's ecology for effective management. Key points include:
- Biotic and abiotic factors influence pest populations and must be understood to manage density. Ecology studies these complex interactions.
- Population characteristics like density, natality, mortality, and dispersal are important to monitor. A balance of these factors determines population growth.
- Effective pest management requires integrating cultural, mechanical, physical, biological and chemical controls within the context of the pest's ecology to keep populations below economic thresholds without adverse environmental impacts.

- Native pigs have a higher digestive capacity and microbial activity in their hindgut compared to improved pigs, allowing them to utilize low-quality feed materials.
- General feeding practices for native pigs include feeding a combination of concentrate and forage twice daily. Feeding practices vary based on life stage from sows and boars getting 1-1.5kg of mixed feed and supplements, to suckling piglets getting ad-libitum starter mash and supplements, to weaners getting 0.3-1kg of mixed feed and supplements.
- Sample mixed feeds for native pigs contain ingredients like rice bran, corn, copra, and molasses. Establishing forage production areas can help minimize feed
Marketing and income potential of philippine native pig (glenda p. fule)Perez Eric
This document discusses native pig farming in the Philippines. It begins by outlining the demand and consumption of pork in the country. It then provides details on marketing the native pig, including potential products (lechon), target markets (lechon consumers), and pricing. The document also analyzes the costs and returns of raising native pigs, including feed costs, sales projections, and estimated profits from selling weanlings and slaughter pigs (lechon-type). In summary, the document finds that native pig farming in the Philippines can be a profitable endeavor.
Health care in native pig production (dr. aleli a. collado)Perez Eric
This document discusses herd health programs for native pig production. It outlines the epidemiologic triad and describes key elements of a herd health program including biosecurity, vaccination against hog cholera, and control of internal and external parasites. Common diseases of pigs are also listed, along with signs of unhealthy animals and preventive measures. First aid recommendations for diarrhea, fever and colds in pigs are provided.
Breed development, production and commecial utilization of native pigsPerez Eric
- Native pigs are an important part of rural farming communities in the Philippines, providing food security, income, and cultural/social roles. However, native pig production typically remains a small-scale backyard activity without consistent profits.
- There is increasing demand for organically and naturally produced foods, as well as interest in conserving native genetic resources. Improved native pig breeds are desired that are adapted to local conditions but also provide uniform, predictable production and product quality.
- A strategy is proposed to develop homogeneous but genetically diverse native pig populations through organized breeding programs, improved production systems, and marketing of native pig products.

R&D initiatives on Philippine Native Pigs Perez Eric
This document discusses enhancing Philippine native pigs to create livelihood opportunities through research and development. It outlines the value of native pigs in providing income and food for rural families as they are resilient to climate extremes. It describes strategies to establish more homogeneous native pig populations through selection while maintaining genetic diversity. This includes establishing true-to-type breeding populations to meet producer and consumer preferences for consistent quality and performance. Research demonstrates improvements in birth weight, 6-month weight and litter size through selection. Native pig production is shown to provide net income for farmers with the right management.
Science-based native pig production to meet quality requirements of native pi...Perez Eric
This document summarizes the presentation of Fabian Maximillan B. Cabriga on science-based native pig production in the Philippines. It discusses the current situation of small-scale native pig farmers, including issues like lack of training, standards, and market support. It then outlines how the Philippine Native Pig Owners Network Association was established in 2015 to address these issues. The association has helped organize farmers, establish stable prices, and promote native pork. It also describes Teofely Nature Farms, a model native pig farm started by Cabriga, and how it aims to produce high quality native pork and vegetables sustainably through good practices.
Benefits and Market Potential of Native Pig Lechon Processing and MarketingPerez Eric
Lechon, or roasted pig, is a Filipino delicacy traditionally made with native Philippine pigs. The document discusses lechon production in La Loma, Philippines, which is considered the lechon capital. Ping Ping Native Lechon & Restaurant is one of the established brands in La Loma that uses 100% native pigs for lechon. While there is steady demand, production is limited by the supply and high costs of quality native pigs. The lechon industry needs government support to address issues around native pig supply and transportation regulations.
Native Pig Trading and Lechon Processing and Marketing in CebuPerez Eric
Ms. Claire C. Silva owns Claire's Lechon de Cebu, which began in 1989 processing one pig per week and has since expanded to processing 10-15 pigs per week normally and up to 40 pigs on weekends during peak seasons. Native pigs from Negros and Bohol are used for their juicy and tasty meat. The pigs are slaughtered and seasoned in-house before being roasted over open wood charcoal. While lechon production has grown, challenges include fluctuating pig prices and quality as well as competition from other processors. Future plans include breeding their own pigs and expanding markets.
The document summarizes a FIESTA event held in Zamboanga City to promote the ZamPen native chicken breed. It discusses the 10 years of research that went into developing the ZamPen breed. The event featured exhibits, forums, and competitions to encourage local farmers and businesses to raise ZamPen chickens as a livelihood option. The goal was to connect producers with potential buyers and introduce technology that can help the native chicken industry. Samples of dishes made from ZamPen chicken were served to event attendees.
The FLS-GEM project trained over 2,500 goat farmers through 28-week courses focusing on improved feeding, breeding, health and waste management. This led to increases in productivity such as higher conception rates, shorter kidding intervals, and greater survival rates and kid weights. Farmers saw higher profits as a result, with income increasing by over 30% on average. The project had wide social impacts as well, with increased cooperation between farmers and new businesses developing around goat farming. The project was so successful that its training model was adopted as the national standard for goat production in the Philippines.
The document discusses an e-learning program on goat raising offered by the DOST-Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD). The program offers free online certificate courses on topics related to goat production. As of November 2017, over 2,100 students have graduated from the program, consisting of farmers, extension workers, businessmen, and overseas Filipino workers. Students can enroll by creating an account on the e-extension website and selecting from the available goat raising course modules.
The document discusses the Test-Interval Method (TIM), a common practice for measuring total milk yield (TMY) in small ruminants. TIM uses a formula that calculates TMY based on milk measurements taken at intervals after birth and between subsequent milkings. It originated as a way for farmers and organizations to evaluate goat performance and rank animals for selective breeding programs to improve genetics. TIM can be used on individual farms or in government programs.
This document discusses standards for slaughtering and cutting goats. It outlines proper procedures for transporting goats to slaughter, ante-mortem and post-mortem inspection, and slaughter methods. Detailed cutting schemes for six prime cuts of chevon are also presented. Adopting these standards would help produce clean meat through proper hygiene, allow for higher carcass recovery, demand higher prices, and serve as a guideline for developing policies around goat slaughtering.
The document summarizes research on a herbal dewormer called MCM for goats. MCM is created from a mixture of three Philippine plants - makahiya, caimito, and makabuhay. Clinical trials showed MCM, administered as either a 500mg capsule or 500ul liquid twice at a 2 week interval, was effective at eliminating the parasitic roundworm Haemonchus contortus in goats. This led to increased health, milk and meat production in treated goats. The document provides details on the formulation, dosage, availability and pricing of the herbal MCM dewormer and encourages farmers to try and support this natural treatment option for healthier goats.
Order : Trombidiformes (Acarina) Class : Arachnida
Mites normally feed on the undersurface of the leaves but the symptoms are more easily seen on the uppersurface.
Tetranychids produce blotching (Spots) on the leaf-surface.
Tarsonemids and Eriophyids produce distortion (twist), puckering (Folds) or stunting (Short) of leaves.
Eriophyids produce distinct galls or blisters (fluid-filled sac in the outer layer)
Cultivation of human viruses and its different techniques.MDAsifKilledar
Viruses are extremely small, infectious agents that invade cells of all types. These have been culprits in many human disease including small pox,flu,AIDS and ever present common cold as well as plants bacteria and archea .
Viruses cannot multiply outside the living host cell, However the isolation, enumeration and identification become a difficult task. Instead of chemical medium they require a host body.
Viruses can be cultured in the animals such as mice ,monkeys, rabbits and guinea pigs etc. After inoculation animals are carefully examined for the development of signs or symptoms, further they may be killed.

Discovery of Merging Twin Quasars at z=6.05Sérgio Sacani
We report the discovery of two quasars at a redshift of z = 6.05 in the process of merging. They were
serendipitously discovered from the deep multiband imaging data collected by the Hyper Suprime-Cam (HSC)
Subaru Strategic Program survey. The quasars, HSC J121503.42−014858.7 (C1) and HSC J121503.55−014859.3
(C2), both have luminous (>1043 erg s−1
) Lyα emission with a clear broad component (full width at half
maximum >1000 km s−1
). The rest-frame ultraviolet (UV) absolute magnitudes are M1450 = − 23.106 ± 0.017
(C1) and −22.662 ± 0.024 (C2). Our crude estimates of the black hole masses provide log 8.1 0. ( ) M M BH = 3
in both sources. The two quasars are separated by 12 kpc in projected proper distance, bridged by a structure in the
rest-UV light suggesting that they are undergoing a merger. This pair is one of the most distant merging quasars
reported to date, providing crucial insight into galaxy and black hole build-up in the hierarchical structure
formation scenario. A companion paper will present the gas and dust properties captured by Atacama Large
Millimeter/submillimeter Array observations, which provide additional evidence for and detailed measurements of
the merger, and also demonstrate that the two sources are not gravitationally lensed images of a single quasar.
Unified Astronomy Thesaurus concepts: Double quasars (406); Quasars (1319); Reionization (1383); High-redshift

2. Terms to Reckon:
infection
presence of a pathogen
in the body but does not
necessarily mean the
presence of clinical signs
disease
occurrence of cases and
outbreaks (with clinical
signs) caused by the
pathogen in a
population
3. ecology branch of biology that deals with the relations of
organisms to one another and to their physical
surroundings
4. transmission passing of a communicable disease from an
infected host individual or group to a particular
susceptible individual or group
5. Diseases affecting livestock can have a
devastating impact on:
1. animal productivity and production,
2. trade in live animals, meat and other
animal products,
3. human health and, consequently,
4. the overall process of economic
development.
7. Macro Level Consequence
1. growing populations Livestock, fastest growing
subsector of agriculture
(true in developed countries)2. income gains and
urbanization
3. result of globalization Unprecedented increase of
emerging and re-emerging
animal diseases and zoonoses4. climate change the world
8. Biological factors1. Environmental, climate, weather changes
(temperature & humidity).
Climate change also has the following effects on disease occurrences:
Increased parasitic zoonoses
(e.g. helminthoses, tick-borne diseases)
Increased spread of vectors and vector-borne diseases
(e.g. Rift Valley fever, West Nile virus)
- Increased humidity increases vector survival; increased rain may
increase larval habitat and vector population size by creating new
habitat
Increased incidence of tropical diseases in areas previously
considered as having temperate climate conditions
(e.g. Old and New World screwworm)
9. •Alteration of disease eco-
epidemiology, new disease
patterns, and change in vector
capacity.
- Decreased rain can
increase container-
breeding mosquitoes by
forcing increased water
storage
- Epic rainfall events can
synchronize vector host-
seeking and virus
transmission
10. •Change in geographic range,
host range and pathogen
virulence.
- at higher temperature
changes there is
decreased extrinsic
incubation period of
pathogen inside the
vector during
transmission season.
11. 2. Ecological and ecosystem changes.
Changes in the current conditions of the ecosystem
affect many animals and cause higher risk for
emergence of diseases and the occurrence of
pathogens and parasites.
12. 3. Animal density and
biomass.
The optimal density
of animals in a specific
location is vital to animal
health.
Overcrowding or high
densities pose high risks
and allow faster transfer
of parasites and pests.
13. 4. Changes in host-pathogen
interactions.
The emergence and re-
emergence of diseases can be
attributed to host-pathogen
interactions.
When these interactions
are interrupted or altered, the
resistance of animals can be
weakened and places them in
vulnerable states.
14. 5. Microbial adaptation to new
environmental conditions.
• Intrinsic properties of the pathogens
that are associated with this are:
a. genetic shift as a result of mutation &
reassortment, as it occurs in avian
influenza virus;
b. conjugation, transformation, and
transduction in bacteria.
c. adaptation to new vectors and hosts
d. development of increased virulence or
drug resistance
15. 6. Changes in land use and use of natural resources.
• Human economic activities cause major changes in land use.
Encroachment into natural animal habitat due to
a.forest clearings and
b.land conversions for various uses such as industry, pasture,
residential space and agriculture
changes in animal and human density and distribution
alters local biodiversity through the introduction of exotic and
invasive species that could cause extinction of one or more
species.
16. Changes in Environment
• Malaysia, 1999, intensive pig farming intrudes into the natural
habitat of fruit bats carrying the Nipah virus
• Entire pig herd of the country slaughtered ($120M); 105 human deaths
17. 7. Increased contacts
between pathogens and
host population
(urbanization, rural peri
urban-urban continuum)
• As a result of urbanization and
industrial conversion animals
are kept in densely populated
areas
• This increases the contacts
between pathogens and hosts
that lead to increased exposure
and risk.
18. 8. Social and cultural practices
Social and cultural practices of man add to the risk of zoonotic
transmission. These are:
• food habits
• religious beliefs
• Halal meat
• free range eggs and meat
• exotic meat
• raw milk
19. Abiotic factors
1. Globalization, international trade, and level of economic
development.
Due to globalization, changes in the movements of human and
animal populations enhance transmission. Likewise, movements
are attributed to:
a. extent of ownership and movement of pets
b. extent of air travel
c. extent of ecotourism, hunting, camping, etc.
d. Introduction of infected host in to new ecosystem. eg :
Marburg Disease
e. natural movement of wild animals including migratory
birds, and by anthropogenic movement of animals.
20. Changes in Movements of human and
animal populations
• Distance and speed of travel
increased 1000 fold since
1800
• 1.4 billion air travelers/year
21. 2. Lack or inadequate
policies for control and
confinement measures.
Policies must focused on
managing and
implementing movement
restrictions of animals and
products from one place to
another, especially across
borders.
Policies and strategies
should be improved to
safeguard animal health,
public health, livelihoods
and food systems.
22. 3. Political and civil strife
and instability.
There is disruption of
health services in war-
torn or impoverished
countries.
Example: War-torn
Kosovo led to
epizootic
rodent
tularemia.
23. 4. Breakdown of public
services in charge of
disease control.
In case of natural
disasters, health
infrastructures are
damaged and control of
diseases that emerged
from the calamity
cannot be mitigated
efficiently and
effectively.
24. 5. Management of animal waste.
Popularity of organic farming and
intensive tilapia inland farming,
poultry manure and other animal
manure became a source of added
income to livestock farmers.
Transporting manure to other
places because of demand is a risk
for transmitting the pathogens.
Wet manure is seeded with viable
viral, bacterial, fungal and protozoal
pathogens that can be harmful to
both man and susceptible animals.
25. Changes in Management of animal wastes
Manure-related fish kills , typical in many countries
26. 6. Poor or change in public
health management.
Poor or change in
management results in lack
of integration with animal
health surveillance,funding
in the public health sector
and sustained funding on
scientific studies to answer
public health questions and
build expertise.
27. 7. Animal welfare philosophies affecting animal production system.
Animal welfare societies have been loud in espousing practices that
should not hinder the natural behavior of animals. Due to increase practice
of range farming however, soil-borne parasites that have been controlled
before occurred such as Trichinella , Toxoplasma, cysticercosis, etc. have re-
emerged.
28. 8. Changes in production systems.
Production systems are currently under
pressure to adjust to rapidly evolving
socio-economic conditions and large
intensive livestock production units.
Increasing demand for animal protein has
led to changes in:
a. farming practices (e.g. large “open”
poultry production units in Asia)
b. animal markets
c. bush meat consumption
d. global trade
e. pig and poultry production have
emerged in many developing regions
in response to the rapidly growing
demand for livestock products.
29. As the intensity of production increases, there is greater complexity and
severity of diseases.
30. The macro-environment can influence the pattern of disease events.
Extreme conditions of the physical environment such as
a. climate,
b. topography,
c. vegetation and
d. soil
can directly cause illness or disease to animals.
Factors affecting pathogen vectors, endemicity, and pathogen vector
diffusion include
a. temperature,
b. relative humidity,
c. vegetation cover and
d. plant species and
e. chemical composition of soils.
Macro-environment and diseases
31.
32. Predicting the presence of
disease using a set of
parameters could accurately
model the observed disease
situation in a certain area.
Predictive mapping could be
useful for the management
control planning in a large
area
33. Micro-environment and diseases
- interaction between biological supports (host animal, vector, and pathogen)
which determine the establishment, multiplication, spread or reduction, and
even elimination of infections.
Host’s capacity to respond to infectious attack:
Susceptibility. The ability to acquire a pathogen and to show a pathological
status.
Tolerance. The relative capacity to control the development of a pathogen and
to limit its pathological effects.
Resistance. The ability to reduce the growth rate, fecundity, and persistence
of a population of pathogens.
Resilience. The ability to grow and be productive despite the presence of a
normal pathogen charge.
Refractoriness. The impossibility to acquire an infection because the biological
support inhibits the multiplication of the pathogen.
34. Micro-environmental interactions and competitions:
Coccidia and helminths.
There is equilibrium at the level of the gastrointestinal tract.
Treatments against coccidia positively affect the multiplication
of gastrointestinal helminths and vice versa.
Tsetse flies, intestinal symbionts and trypanosome infections:
There are symbiotic micro-organisms (Wigglesworthia glossinidia)
inside the intestine of tsetse flies give a degree of immunity to
acquire and transmit trypanosome infections
36. •The habitat in which an infectious agent normally
lives, grows, and multiplies.
•The reservoir may or may not be the source from
which an agent is transferred to a host.
•For example, the reservoir of clostridium botulinum
is soil, but the source of most botulism infections is
improperly canned food containing C. Botulinum
spores.
Reservoir
37. Reservoir
1. Human reservoirs- cases
and carriers
2. Animal reservoirs- cases
and carriers
3. Environment reservoirs-
plants, soil and water
38. •Carriers commonly transmit
disease because they do not
recognize they are infected
and consequently take no
special precautions to prevent
transmission.
•Symptomatic persons are
usually less likely to transmit
infection
Human Carriers
40. •Many fungal agents, such as
those causing
histoplasmosis, live and
multiply in the soil.
•The primary reservoir of
Cryptosporidiosis is water
Environmental reservoirs
42. Mode of Transmission
•The route of infection refers to the
path which the disease agent used to
gain access to the body of the
susceptible host
•Mode of transmission to the method
of transference.
43. Example: Route vs Mode
•The route from Point A to Point B is
through the main highway (route of
infection).
•However, the journey from point A to
point B using the main highway can be
completed using any of the transportation
options: by public bus, railway transit or
private vehicle (mode of transmission).
45. Interventions to improve livestock
and agriculture production systems
require policies that address
interventions in
• socio-economic dimensions,
• institutional support,
• training and information,
• land use, land tenure, and
natural resource management,
and
• increasing agricultural
production.
