Three-hundred-and-seventy-eight strains of coliform bacteria were isolated from specimens of commonly sold milk and food products. Klebsiella and Enterobacter spp. were predominating. Resistance to sulphonamides, streptomycin, and chloramphenicol occurred in only 5, 1, and 2 strains, respectively. No tetracycline-resistant strains were found. Two-hundred-and-two strains (54 were resistant to ampicillin. In genetic crosses with a sensitive strain of E. coli Κ 12 W 3132 transmissible R factors could not be demonstrated in any of the resistant coliform strains. It is concluded that food is not a significant source of antibiotic resistant enteric bacteria. It may, however, be suggested that food is a source of potentially pathogenic gram-negative bacteria which points out the importance of strict hygienic surveillance of food production.
从常见销售的牛奶和食品样本中分离出378株大肠菌群细菌。克雷伯菌属和肠杆菌属占主导。分别仅有5株、1株和2株对磺胺类药物、链霉素和氯霉素耐药。未发现四环素耐药菌株。202株（54%）对氨苄青霉素耐药。在与大肠杆菌敏感菌株Κ 12 W 3132进行的遗传杂交中，未在任何耐药大肠菌群菌株中证明有可传递的R因子。得出的结论是，食物不是抗生素耐药性肠道细菌的重要来源。然而，可以认为食物是潜在致病革兰氏阴性菌的一个来源，这指出了对食品生产进行严格卫生监测的重要性。
