On a farm with therapeutic problems and unsatisfactory management conditions, the occurrence of antibiotic resistance and transferable antibiotic resistance has been studied in E. coli isolated from calves which were 5 and 30 days old. Strains with resistance to up to seven antibiotics as well as transferable resistance against up to five antibiotics were recorded. On an average, 4.2 strains with different patterns and 4.0 different strains with transferable resistance were isolated from each calf. The corresponding figures previously found for healthy control calves were 1.6 and 1.1 strains, respectively. Resistance and transferable resistance were most common against sulphonamide and penicillin.
在一个存在治疗问题且管理条件不尽人意的农场，对从5日龄和30日龄犊牛分离出的大肠杆菌中的抗生素耐药性及可转移抗生素耐药性的发生情况进行了研究。记录到了对多达七种抗生素具有耐药性以及对多达五种抗生素具有可转移耐药性的菌株。平均而言，每头犊牛分离出4.2种具有不同模式的菌株和4.0种具有可转移耐药性的不同菌株。先前在健康对照犊牛中发现的相应数字分别为1.6种和1.1种菌株。对磺胺类药物和青霉素的耐药性及可转移耐药性最为常见。
