Antimicrobial susceptibility of thermophilic Campylo-bacter spp. isolated from environmental samples.

ABSTRACT

Environmental samples were subjected to determine frequency of occurrence of pathogenic campylobacters in the environment. The antimicrobial susceptibility of the isolates was tested to evaluate the level of antibiotic sensitive campylobacters in the environment of investigation. In all, 70 Campylobacter isolates were obtained from water and domestic animal faeces samples using Kapadnis-Baseri device and antimicrobial susceptibility of them was determined by disc diffusion test and E- test. The results indicated that all the isolates of Campylobacter were sensitive to ciprofloxacin and resistant to cefotaxime, cephalexin and ampicillin. Lowest MIC values were observed for ciprofloxacin and gentamicin (2 microg/mL) and highest MIC values for ampicillin and chloramphinicol (256 microg/mL). In general, pathogenic Campylobacter spp. were prevalent in large numbers in the environment, however, they were sensitive to ciprofloxacin.
