Article Abstract
The present study aims to identify genomic variants through a whole genome sequencing (WGS) approach and uncover biological pathways associated with adaptation and fitness in Indian yak populations. A total of 30 samples (10 from each population) were included from Arunachali, Himachali and Ladakhi yak populations. WGS analysis revealed a total of 32171644, 27260825, and 32632460 SNPs and 4865254, 4429941, and 4847513 Indels in the Arunachali, Himachali, and Ladakhi yaks, respectively. Genes such as , , , , and the novel transcript were found to have the maximum number of high impact variants in all three yak populations, and might play a major role in local adaptation. Functional enrichment analysis of genes harboring high impact SNPs revealed overrepresented pathways related to response to stress, immune system regulation, and high-altitude adaptation. This study provides comprehensive information about genomic variants and their annotation in Indian yak populations, thus would serve as a data resource for researchers working on the yaks. Furthermore, it could be well exploited for better yak conservation strategies by estimating population genetics parameters ., effective population size, inbreeding, and observed and expected heterozygosity.

Breast milk is rich in bioactive proteins and oligosaccharides, including osteopontin (OPN) and 2'-fucosyllactose (2'-FL), which are believed to promote the growth of beneficial microbiota and regulate intestinal barrier function. In this study, fermentation substrates including DOPN (digested OPN fragment), 2'-FL and their combinations in varying proportions, were prepared through in vitro gastrointestinal digestion, dialysis and freeze-drying. Changes in gas production, organic acid levels, ammonia N concentration and bacterial population abundance were studied using an in vitro batch fermentation model, with feces inocula from healthy infants.

Introduction: Ovine gammaherpesvirus 2 (OvGHV2) is the cause of sheep-associated malignant catarrhal fever (SA-MCF). Although SA-MCF is endemic in most geographical regions of Brazil, outbreaks are more frequently reported in the State of Rio Grande do Sul (RS). This report describes the findings of an SA-MCF outbreak in cattle from RS and investigates the possible reasons for the elevated occurrence of outbreaks in cattle from this geographical region of Brazil.

Introduction: are commonly found in intramammary infections associated with bovine subclinical mastitis in dairy cattle, yet their genomic diversity and antimicrobial resistance dynamics remain poorly characterized, particularly in African settings.
Methods: This study presents a comparative genomic analysis of 17 isolates from South Africa, including five newly sequenced bovine mastitis strains and twelve porcine-derived genomes retrieved from GenBank. analysis using multilocus sequence typing (MLST), virulence genes, antibiotic resistance genes and plasmids replicon types were used to characterise these isolates.
Hepatitis E virus (HEV) has emerged as a major agent of acute viral hepatitis, with zoonotic genotype 4 (HEV-4) representing a public health concern in China. In this study, we integrated province-wide enhanced hepatitis E surveillance data and molecular profiling from Shandong Province of eastern China, 2019-2023, with the aim of elucidating the epidemiology, genetic diversity, and clinical correlations of autochthonous HEV infections. In total, 5826 cases were reported during the study period, with 72.

Fluralaner is an isoxazoline acaricide with potent activity against Rhipicephalus (Boophilus) microplus, a major tick species affecting cattle in South America. In this study, larval bioassays were performed to evaluate the baseline susceptibility of R. microplus populations from Brazil and Argentina to fluralaner.
