Escherichia coli in diarrhoeic lambs: Prevalence, virulence and antibiotic resistance.

The present study aimed to detect the prevalence, virulence and antimicrobial resistance genes profile of Escherichia coli isolated from diarrhoeic lambs. A total of 61 faecal samples were collected from diarrhoeic lambs. The presence of various virulence and antimicrobial resistance genes in E.

Pedigree-based analysis of population structure and genetic diversity in high-milch Vrindavani crossbred cattle of India.

The present study aimed to elucidate the population structure and genetic diversity along with the estimation of genealogical parameters in Vrindavani cattle using pedigree data. The study was based on pedigree data on 12,718 animals, spread across multiple generations during a 52-year period (between 1971 and 2023). The pedigree data was used to estimate different population genealogical parameters including the generation interval; pedigree completeness; rate and level of inbreeding; effective population size; and parameters characterizing the probabilities of gene origin.
