Abstract : Escherichia coli is a poultry bacterial pathogen reported for causing a wide variety of disease. The aim of this research was to determine the antibiotic susceptibility of pathogenic Escherichia coli isolated from liver and trachea of freshly dead chicken. Ninety seven (97) freshly dead chicken from 23 different farms where analyzed for the presence of pathogenic E. coli. In vitro susceptibility of the isolates against antimicrobial agents was determined using disk diffusion method. A total of forty eight (48) pathogenic E. coli were isolated, twenty one (21) of the isolates were recovered from the chicken trachea while twenty seven (27) were from the liver. A total of 43 out of the 48 isolated E. coli showed haemolysis on sheep blood agar, which constituted 89.6% of the entire E. coli. The overall resistant pattern of the isolated E. coli showed that Nitrofurantoin (NIT 300 Î¼g) had the best antimicrobial activity with resistance of 20.8%. Ampicillin (AMP 10 Î¼g) was most resisted with 89.6 % of the E. coli forming resistance. The resistant of other antibiotic used are Ceftazidime (CAZ 30 Î¼g) 45.8%, Cefuroxime (CRX 30 Î¼g) 60.4%, Gentamicin (GEN 10 Î¼g) 68.8%, Ciprofloxacin (CPR 5 Î¼g) 47.9%, Ofloxacin (OFL 5 Î¼g) 52.1%, and Amoxicillin/Clavulinate (AUG 30 Î¼g) 79.2%.
