A PRELIMINARY REPORT ON ANTIBIOTIC RESISTANT ESCHERICHIA COLI NON-0157 ISOLATED FROM CATTLE IN KADUNA STATE, NIGERIA
Keywords:Antimicrobial sensitivity, Escherichia coli, cattle, Nigeria
A total of two hundred and forty (240) faecal samples were obtained from apparently healthy (233) and diarrhoeic (7) cattle in 8 randomly selected commercial farms in Kaduna State, Nigeria. Presumptive E. coli colonies from 76 (31.2 %) faecal samples were confirmed based on standard procedure. Characterization of isolates revealed three heterogeneous serogroups (O111, O118 and O126) from 6 apparently healthy cattle, while no E. coli serogroup was isolated from diarrhoeic cattle. Six (6) non-O157 serogroups obtained from cattle faeces were tested for antimicrobial susceptibility. The antimicrobial susceptibility test indicated that isolates from cattle faeces were 100 % resistant to nitrofurantoin, amoxicillin and cefuroxime, and 100 % sensitive to ciprofloxacin and ofloxacin. The study confirmed cattle as important source of antibiotic-resistant enterohaemorrhagic Escherichia coli in Kaduna state, Nigeria.
