Transfer of drug resistance was readily achieved from strains isolated from both healthy and sick farm chickens, and from diarrhoeic chickens; it was more difficult to demonstrate in strains from domestic chickens. Resistant E. coli showing serotypes suspected to be enteropathogenic for man, i.e. 0126: K71 (B16), 044: K74 (L) and 0119: K69 (B14), were isolated from faecal samples of healthy and sick farm chickens, but not from healthy domestic birds. © 1989.Mahidol UniversityAgricultural and Biological SciencesImmunology and MicrobiologyVeterinaryArticleSCOPUS10.1016/0378-1135(89)90032-1
