MICs of tetracyclines were determined for 86 human Bifidobacterium isolates and three environmental strains. The tet(O) gene was found to be absent in these isolates. tet(W) and tet(M) were found in 26 and 7%, respectively, of the Bifidobacterium isolates, and one isolate contained both genes. Chromosomal DNA hybridization showed that there was one chromosomal copy of tet(W) and/or tet(M).
对86株人源双歧杆菌分离株和3株环境菌株测定了四环素的最低抑菌浓度(MIC)。在这些分离株中未发现tet(O)基因。在双歧杆菌分离株中,分别有26%和7%的菌株含有tet(W)和tet(M),且有一株同时含有这两个基因。染色体DNA杂交显示tet(W)和/或tet(M)有一个染色体拷贝。
