Klebsiella oxytoca Isolated from nostrils of dromedary camels: Resistance pattern and pehX Gene based genotyping

The present study was aimed to characterise Klebsiella oxytoca obtained from nostrils of camels (Camelus dromedarius) with special reference to antibiotic resistance pattern. Total 68 samples of infected camels were examined and out of these, 33 (48.53%) were found to be positive for K. oxytoca, which were further confirmed phenotypically and genotyped by species specific primer based on pehX gene of 344bp amplicon size. The isolates were characterised for biochemical properties and analysed to evaluate the susceptibility against 26 antimicrobials. It was found that 100% isolates were resistant to eight antibiotics namely amoxycillin, ampicillin, bacitracin, clindamycin, oxacillin, rifampicin, sulfadiazine and vancomycin, while all isolates were completely sensitive to cefepime and imipenem. Variable resistance patterns were recorded for other studied antibiotics.
