Abstract


Antibiotic resistance patterns of Escherichia coli in human, pet, livestock and poultry living in close contact was carried out. A total of 130 fecal samples were obtained from human and animals.  Out of 124 isolates with characteristics E. coli morphology obtained on Eosin methylene blue (EMB) agar, only forty (32.3%) isolates were identified as E. coli.  Of all the E. coli isolates, 100% resistance to cotrimozaxole was obtained from cattle, poultry and goats while human, sheep and dog showed 92.3%, 81.8% and 58.3% resistance respectively.  Isolates from dog showed no resistance to gentamicin, amoxicillin and augmentin, but exhibited more than 58.3% resistance to other antibiotics. Isolates from cattle, poultry, sheep and goats were generally resistant to all the antibiotics tested with percentage resistance ranging from 14.29% (augmentin) to 100% (cotrimozaxole).  Notable is the increasing resistance of both the human and animal isolates to some antibiotics that are considered highly effective against resistant E. coli such as ofloxacin (31.8%), nalidixic acid (50.0%) and nitrofurantoin (76.1%).
