DETERMINATION OF ANTIBIOGRAM PATTERN IN ESCHERICHIA COLI STRAINS ISOLATED FROM CATTLE FAECES.

Escherichia coli is the one of the major challenge in regards to antibiotic resistance phenomena. It has not only significantly associated with many animal diseases but also important for high level of antibiotic resistance. The present study has designed to determine antibiogram pattern of E. coli strains obtained from cattle diarrhoeic faeces. Total 31 genotypically confirmed E. coli isolates were obtained from 40 samples and screened for 16 antibiotics. It was found that 90.32% isolates were sensitive against cefepime, chloramphenicol and ceftrioxane followed by 87.09% sensitive to levofloxacin, 80.64% to polymyxin-B, 77.41% gentamicin, 67.74% ampicillin/sulbactam, 54.83% ticarcillin and tetracycline, 51.61% streptomycin, 48.38% ampicillin, 41.93% isolates were sensitive to cephotaxime. The all isolates were 100% resistant to penicillin and rifampicin. Further, this study suggested molecular characterization of isolates in context of genetic mechanisms involve in antibiotic resistance. [ABSTRACT FROM AUTHOR]
