Abstract

The multiresistance gene cfr was identified for the first time in an Enterococcus faecalis isolate of animal origin. The 32,388-bp plasmid pEF-01, which carried the cfr gene, was sequenced completely. Three copies of the insertion sequence IS1216 were identified in pEF-01, and the detection of a cfr- and IS1216-containing amplicon by inverse PCR suggests that IS1216 may play a role in the dissemination of cfr by a recombination process.

摘要

耐多药基因 cfr 最初在一株动物源屎肠球菌分离株中被发现。携带 cfr 基因的 32388bp 质粒 pEF-01 被完全测序。在 pEF-01 中鉴定出三个插入序列 IS1216,反向 PCR 检测到含有 cfr 和 IS1216 的扩增子表明,IS1216 可能通过重组过程在 cfr 的传播中发挥作用。
