Prevalence status and detection of benzimidazole resistance using AS-PCR in Haemonchus contortus of goats from Marathwada region, Maharashtra, India.

This study examined Haemonchus contortus prevalence and benzimidazole resistance in eight districts of Marathwada, Maharashtra, India. A comprehensive investigation of 264 abomasa of goats collected from abattoirs and goats necropsied at the College of Veterinary Sciences and Animal Husbandry, Parbhani, revealed 21.21 % a prevalence of H.

Evaluation of genetic diversity and population structure of West-Central Indian cattle breeds.

Evaluations of genetic diversity in domestic livestock populations are necessary to implement region-specific conservation measures. We determined the genetic diversity and evolutionary relationships among eight geographically and phenotypically diverse cattle breeds indigenous to west-central India by genotyping these animals for 22 microsatellite loci. A total of 326 alleles were detected, and the expected heterozygosity ranged from 0.

Detection of virulence determinants by real time PCR in E. coli isolated from mutton.

Ninety three Escherichia coli isolates belonging to 35 serotypes isolated from market mutton were tested to find out the prevalence of virulence determinants, Verotoxin 1 (VT1), Verotoxin 2 (VT2), Intimin (eae) genes and enterohemolysin production. Real Time PCR based detection was carried out for virulence genes using SYBR green format and amplicons were confirmed by melt curve analysis. Prevalence of VT1 gene in these isolates was much higher (38.
