Thirty nine Escherichia coli E. coli isolated from septicaemic clinical cases between October 2005 and March 2006 from eleven poultry farms in Abeokuta, South West Nigeria were tested for their in vitro antimicrobial drug sensitivity pattern. The E. coli were isolated from two hundred and fifty samples comprising of intestine, kidneys, lungs, hearts, ovary, spleen and colo-rectum from diseased chickens mostly commercial layers submitted for post-mortem examination. Eight of the poultry farms studied disclosed that they had used between 3 to 7 different antimicrobial agents either for treatment, prophylaxis or as growth promoters within the studied period. The result indicated that the 39 E. coli isolates showed nineteen different multidrug-resistant patterns to Nitrofurantoin 100 μg, Cefuroxime 20 μg, Norfloxacin 10 μg, Cotrimoxazole 50 μg, Ciprofloxacin 5 μg, Nalidixic acid 30 μg, Chloramphenicol 10 μg, Ampicillin 10 μg, 25 μg, Ofloxacin 5 μg, Penicillin G 5 i.u, Amoxycillin 20 μg, and Cloxacillin 5 μg, 10 μg discs that were tested.
