To clarify the factors for occurrence of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli on broiler, two flocks (1 day of age) feeding diet with or without antibiotics were kept to a broiler house sanitized with disinfectants. ESBL-producing E. coli, however, was detected at a concentration of over 106 CFU/g of feces from 9 days of age to 49 days of age in both broiler flocks. Therefore it was indicated that the antibiotics other than cephalosporins used in this study have no effect due to co-selection on the numbers of ESBL-producing E. coli in broiler feces in this term. When a flock was kept with diet with antibiotics for 49 days in a laboratory animal room, no ESBL-producing E. coli was detected in the flock. These results suggest that the occurrence of ESBL-producing E. coli may not be related to feed with antibiotics, and the contamination of ESBL-producing E. coli in broiler houses might be an important factor.
