This document discusses the application of whole genome sequencing in infectious disease diagnostics. It provides examples of how genome sequencing has been used to identify bacterial species, detect antibiotic resistance genes, and study outbreaks. The document also discusses challenges around regulatory approval of genomic tests, data sharing policies, and database management. Overall, it argues that whole genome sequencing is a valuable tool but that standards must be developed to ensure high quality data.
The document discusses oomycete genomics past, present and future. It summarizes that 5 oomycete genome sequences are currently available with several more underway. Next generation sequencing technologies are accelerating the rate of new sequence generation extraordinarily. The rapid accumulation of sequence data means approaches that integrate data like the VBI Microbial Database and miGenome project will be needed. Undergraduate research in oomycete bioinformatics offers benefits to the community and as a learning experience.

Clinical Metagenomics for Rapid Detection of Enteric Pathogens and Characteri...QIAGEN
High-throughput sequencing, combined with high-resolution metagenomic analysis, provides a powerful diagnostic tool for clinical management of enteric disease. Forty-five patient samples of known and unknown disease etiology and 20 samples from health individuals were subjected to next-generation sequencing. Subsequent metagenomic analysis identified all microorganisms (bacteria, viruses, fungi and parasites) in the samples, including the expected pathogens in the samples of known etiology. Multiple pathogens were detected in the individual samples, providing evidence for polymicrobial infection. Patients were clearly differentiated from healthy individuals based on microorganism abundance and diversity. The speed, accuracy and actionable features of CosmosID bioinformatics and curated GenBook® databases, implemented in the QIAGEN Microbial Genomics Pro Suite, and the functional analysis, leveraging the QIAGEN functional metagenomics workflow, provide a powerful tool contributing to the revolution in clinical diagnostics, prophylactics and therapeutics that is now in progress globally.
Genetic mapping of behaviour and gene expression in the chickenMartin Johnsson
This document discusses genetic mapping of behavior and gene expression in chickens. It begins by outlining the goals of understanding what genetic mapping and eQTL mapping can reveal, what data is needed, and the analysis workflow. It then provides background on genetic mapping and eQTL mapping terminology and methodology. Examples are given of a genetic mapping study that identified a QTL for a behavior and eQTL for a gene in chickens. The data and study populations needed are described. Finally, it concludes that genetic mapping can associate trait differences with genetic markers and locate broad chromosomal regions requiring further investigation, while eQTL mapping identifies genes underlying associations.
The Global Virome Project is a 10-year global effort to identify and characterize naturally occurring viruses with pandemic potential. It aims to build a comprehensive database of the estimated 1.6 million viral species circulating in mammals and waterfowl. This will allow researchers to develop broad-spectrum countermeasures against future zoonotic viruses and identify high-risk viruses to prevent spillover. The project will sample viruses in 108 sites across 63 countries over 10 years, prioritizing countries and species based on viral discovery rates and zoonotic risk prediction models. The goal is to capture over 85% of the global mammalian virome to transform virology and pandemic preparedness.

How to transform genomic big data into valuable clinical informationJoaquin Dopazo
This document discusses how to transform genomic big data into valuable clinical information. It begins by defining genomic big data and explaining how individual genome data contains more information than the original experiment. Next, it discusses lessons learned from genome-wide association studies, including that many loci contribute to traits and there is evidence of pleiotropy. However, individual genes cannot fully explain trait heritability. The document then discusses challenges in detecting disease-related variants from exome/genome sequencing data due to the large number of variants and presence of apparently deleterious variants in healthy individuals. It suggests taking a systems approach considering interactions and multigenicity to better understand variation and disease mechanisms.

CHARACTERISING FOOT-AND-MOUTH DISEASE VIRUS IN CLINICAL SAMPLES USING NANOPOR...EuFMD
This study evaluated the use of the Oxford Nanopore MinION sequencer to characterize foot-and-mouth disease virus (FMDV) in different sample types. A single PCR was used to amplify FMDV from cell culture and clinical samples of three serotypes. MinION sequencing generated long reads that were used to assemble reference genomes, achieving 99.97-100% identity to references from Illumina MiSeq sequencing. The MinION was able to characterize FMDV strains in real-time from various sample matrices across serotypes, demonstrating its potential for rapid outbreak analysis and vaccine selection. Future studies could validate this on more samples and all FMDV serotypes.
This document discusses the use of bioinformatics tools to analyze gene expression data and detect tumors and mutations in tissues. It summarizes the PhyloMap technique, which integrates principal coordinate analysis, vector quantization, and phylogenetic tree construction to provide improved visualization of large genomic data sets. PhyloMap allows researchers to better analyze and predict evolutionary relationships among influenza A virus genes. The document concludes that PhyloMap is an efficient algorithm for analyzing phylogenetic relationships in large genomic data compared to other techniques.

The document discusses the strengths, weaknesses, opportunities, and threats (SWOT) of using whole genome sequencing (WGS) for surveillance and diagnostics of zoonotic bacteria. It provides a case study of using WGS to track the nosocomial transmission of Pseudomonas aeruginosa between patients and the hospital water supply. WGS was able to identify transmission routes and microevolution of the bacteria with single nucleotide resolution. However, challenges include the need for robust and standardized analysis methods as well as experimental design considerations. Overall, WGS provides opportunities for improved outbreak tracking, classification, and diagnostics if its strengths are leveraged and weaknesses addressed.
Amany m. elshamy why the negative covid19 pcr test is a misguide resultsAmany Elshamy
The document discusses limitations of PCR tests for COVID-19 diagnosis. PCR tests have sensitivity of 70-90% and false negatives are common within the first week of infection or after 15 days. Commercial PCR kits target genes like ORF1ab, E, N and RdRP which have high genetic diversity and mutations, reducing accuracy. Serology tests have increasing sensitivity after the first week but depend on viral activity and cannot determine active infection. Chest CT is more reliable than PCR for diagnosis, showing characteristic lung opacities. Improved COVID-19 diagnostics are needed to enhance early reporting and accurately diagnose asymptomatic cases.
1. The study performed whole-exome sequencing on 72 cases of familial Meniere's disease to identify rare variants in genes associated with sensorineural hearing loss (SNHL).
2. Analysis identified that 40% of cases carried at least one novel or ultra-rare variant in SNHL genes, suggesting these genes play a role in Meniere's disease.
3. The OTOF gene showed a significant accumulation of rare variants compared to controls. A common intronic variant in OTOF, rs34796712, which regulates its expression, occurred less frequently in cases also carrying a rare variant, suggesting it may play a protective role.

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.
This presentation offers a general idea of the structure of seed, seed production, management of seeds and its allied technologies. It also offers the concept of gene erosion and the practices used to control it. Nursery and gardening have been widely explored along with their importance in the related domain.
Mapping the Growth of Supermassive Black Holes as a Function of Galaxy Stella...Sérgio Sacani
The growth of supermassive black holes is strongly linked to their galaxies. It has been shown that the population
mean black hole accretion rate (BHAR) primarily correlates with the galaxy stellar mass (Må) and redshift for the
general galaxy population. This work aims to provide the best measurements of BHAR as a function of Må and
redshift over ranges of 109.5 < Må < 1012 Me and z < 4. We compile an unprecedentedly large sample with 8000
active galactic nuclei (AGNs) and 1.3 million normal galaxies from nine high-quality survey fields following a
wedding cake design. We further develop a semiparametric Bayesian method that can reasonably estimate BHAR
and the corresponding uncertainties, even for sparsely populated regions in the parameter space. BHAR is
constrained by X-ray surveys sampling the AGN accretion power and UV-to-infrared multiwavelength surveys
sampling the galaxy population. Our results can independently predict the X-ray luminosity function (XLF) from
the galaxy stellar mass function (SMF), and the prediction is consistent with the observed XLF. We also try adding
external constraints from the observed SMF and XLF. We further measure BHAR for star-forming and quiescent
galaxies and show that star-forming BHAR is generally larger than or at least comparable to the quiescent BHAR.

The use of probiotics and antibiotics in aquaculture production.pptxMAGOTI ERNEST
Aquaculture is one of the fastest growing agriculture sectors in the world, providing food and nutritional security to millions of people. However, disease outbreaks are a constraint to aquaculture production, thereby affecting the socio-economic status of people in many countries. Due to intensive farming practices, infectious diseases are a major problem in finfish and shellfish aquaculture, causing heavy loss to farmers (Austin & Sharifuzzaman, 2022). For instance Bacterial fish diseases are responsible for a huge annual loss estimated at USD 6 billion in 2014, and this figure has increased to 9.58 in 2020 globally.
Disease control in the aquaculture industry has been achieved using various methods, including traditional means, synthetic chemicals and antibiotics. In the 1970s and 1980s oxolinic acid, oxytetracycline (OTC), furazolidone, potential sulphonamides (sulphadiazine and trimethoprim) and amoxicillin were the most commonly used antibiotics in fish farming (Amenyogbe et al., 2020). However, the indiscriminate use of antibiotics in disease control has led to selective pressure of antibiotic resistance in bacteria, a property that may be readily transferred to other bacteria (Bondad‐Reantaso et al., 2023a). Traditional methods are ineffective against controlling new disease in large aquaculture systems. Therefore, alternative methods need to be developed to maintain a healthy microbial environment in aquaculture systems, thereby maintaining the health of the cultured organisms.
