Prevalence and antibiotic resistance pattern of bacteria from clinical and subclinical cases of bovine mastitis in Jammu region

Abstract

Bacterial agents (215) were isolated and identified from 105 clinical and subclinical mastitic milk samples in Jammu region. Staphylococc(were predominant causal agent followed by streptococci, Corynebacterium, micrococci, Proteus, E. coli and Pseudomonas. Gentamicin proved the most effective antibiotic followed by ciprofloxacin, streptomycin, tetracycline, amikacin, norfloxacin, chloramphenicol, carbenicillin and kanamycin in descending order. Most of the isolates exhibited a high level resistance against other antibiotics. Pretesting is necessary to find out an effective antimicrobial agent to be used by veterinarians.
