Abstract
Escherichia coli strains isolated from clinically healthy and sick animals in Lagos and Oyo States of Nigeria were tested for drug resistance and distribution of R-factors. Fifteen multiple and 3 single (OT, S, S3) antibiotic resistance patterns were obtained among 333 isolates. Of the 285 resistant strains, 133 transfered their resistant determinant to sensitive E. coli K12 recipients in part or as a block. None of the donors had sex pili and they were not lysed by Ms2 phage. It required about 2 h for E. coli K12 to acquire a resistance determinant from E. coli strains Nos. 295, 62 and 67 habouring resistance to oxytetracycline, streptomycin and compound of sulphonamides (S3). The number of recipient cells that formed transconjugants increased with the time of incubation.
从尼日利亚拉各斯州和奥约州临床健康和患病动物中分离的大肠杆菌菌株进行了耐药性和r因子分布检测。333株菌株获得15种多重耐药模式和3种单一耐药模式(OT、S、S3)。在285株耐药菌株中，133株将其耐药决定因素部分或作为一个块转移给敏感的大肠杆菌K12受体。供体均无性毛，也未被Ms2噬菌体裂解。大肠杆菌K12从对土霉素、链霉素和磺胺类化合物耐药的大肠杆菌295、62和67株中获得耐药决定因子需要约2 h (S3)。随着孵育时间的延长，形成转缀合物的受体细胞数量增加。
