A high prevalence of multiple antibiotic resistance was observed in populations of Escherichia coli isolated from fecal samples and the carcasses of poultry in a University farm. Almost all of the cultures were resistant to tetracycline, streptomycin, ampicillin and sulfoamide. Association between antibiotics used for prophylaxis or growth promotion and isolation of E. coli with resistance to these antibiotics was observed. One hundred of 648 (15.43%) of resistant cultures of E. coli isolated from fecal samples and the carcasses were capable of transferring resistance determinants to a laboratory strain of E. coli K-12.
在一所大学农场从粪便样本和家禽尸体中分离出的大肠杆菌群体中，观察到多重抗生素耐药性的高流行率。几乎所有培养物都对四环素、链霉素、氨苄青霉素和磺胺类药物耐药。观察到用于预防或促进生长的抗生素与分离出对这些抗生素耐药的大肠杆菌之间存在关联。从粪便样本和尸体中分离出的648株耐药大肠杆菌培养物中有100株（15.43%）能够将耐药决定因子转移至大肠杆菌K-12实验室菌株。
