This study phenotypically characterized indigenous breeds of chickens in regional Sierra Leone and analyzed the prevalence of E. coli isolate in fecal swabs of both indigenous and other exotic breeds of chicken. Five distinct ecotypes were identified with no significant differences (P>0.05) in morphological appearance. Qualitatively, orange and yellow eye colors were commonly found; brown and yellow beak colors predominate in the Normal and Frizzle, with single comb type observed in all breeds. The Kebu showed 100% grey shanks. Body parameters were also not significant (P>0.05). However, the Kebu showed better character than others did. An average resistance to antibiotics was shown for Sulphathiazole (97%), Ampicillin (30.4%), and Chloramphenicol (3.0%). E. coli isolates from the Kebu exhibited resistance to all the antibiotics used, while, E. coli isolates from all breeds showed resistance to Sulphathiazole and Ampicillin. All isolates were 100% susceptible to cefepime, and 92.3% susceptible to cephalosporin.
