Abstract

We studied the DNA sequence variation of van genes of 34 isolates of Enterococcus spp. The isolates containing the vanB gene exhibited between 0 and 41 base pair changes per 801 bp studied when the vanB sequences were compared to that of the reference strain Enterococcus faecalis V583. The isolates carrying the vanC-2 gene exhibited between 0 and 23 base pair changes per 346 bp studied when the vanC-2 sequences were compared to that of the reference strain E. casseliflavus ATCC 25788. Little variation was noted in the vanA and vanC-1 genes.

摘要

我们研究了34株肠球菌属菌株van基因的DNA序列变异情况。当将含有vanB基因的菌株的vanB序列与参考菌株粪肠球菌V583的序列进行比较时,在所研究的801 bp中,每801 bp碱基对变化为0至41个。当将携带vanC - 2基因的菌株的vanC - 2序列与参考菌株格氏肠球菌ATCC 25788的序列进行比较时,在所研究的346 bp中,每346 bp碱基对变化为0至23个。vanA和vanC - 1基因的变异较小。
