Abstract

One hundred eighty Escherichia coli strains isolated from raw and cooked dressed beef and from healthy humans were screened for resistance to each of nine antibiotics: chlortetracycline, ampicillin, chloramphenicol, kanamycin, neomycin, nalidixic acid, dihydrostreptomycin, oxytetracycline, and tetracycline. Nearly 80% of the 98 beef isolates and 54% of the 82 human isolates were resistant to one or more of the antibiotics tested. Ampicillin resistance was most frequent among beef isolates, and dihydrostreptomycin resistance was most frequent among isolates of human origin. About 74% of the multiply resistant beef strains and 85% of the multiply resistant human strains transferred all or part of their resistance to E. coli K-12 recipients.

摘要

对从生熟处理牛肉以及健康人体中分离出的180株大肠杆菌菌株进行了九种抗生素耐药性筛查,这九种抗生素分别是:金霉素、氨苄青霉素、氯霉素、卡那霉素、新霉素、萘啶酸、双氢链霉素、土霉素和四环素。在98株牛肉源分离菌株中,近80%对一种或多种受试抗生素耐药;在82株人体源分离菌株中,54%对一种或多种受试抗生素耐药。氨苄青霉素耐药性在牛肉源分离菌株中最为常见,双氢链霉素耐药性在人体源分离菌株中最为常见。约74%的多重耐药牛肉菌株和85%的多重耐药人体菌株将其全部或部分耐药性转移给了大肠杆菌K-12受体菌。
