Isolation And Antimicrobial Resistance Of Escherighia Coli From Carcasses Of Slaughtered Cows At Ubakala Slaughterhouse In Umuaha South Abia State

ABSTRACT

 A total of 50 carcass swab samples were collected and screened. But 3 2(64%) isolates of E. coil were identified by colony identification and confirmed by biochemical tests. The E. coli isolates were tested for sensitivity against eight (8) antibiotics including tetracycline, ampicillin kamamycin, gentamicin, streptomycin chioramphenicol, amoxicillin and sulfamethoxazole/trimethoprim,. The isolates varied in their antibiotic susceptibility pattern. Sixty four percent (64%) of the isolates were resistant to more than one antimicrobial agent. The antibiotic most sensitive and least , sensitive to the isolates are kanamycin and tetracycline respectively. Kanamycin was sensitive to 28(87.5%) of the total isolates whereas 28(81.25%) showed resistance to tetracycline. The study showed that multidrug resistance E. coil isolates are prevalent In cattle at Ubakala and a considerable portion of E. coil isolates from fresh cattle carcasses is resistant to a variety of antimicrobial agents.
