Multilocus enzyme electrophoresis was used to examine genetic relationships among and between toxigenic and non-toxigenic isolates of Vibrio cholerae O1 obtained from patients and the environment in the US Gulf Coast and surrounding areas. A total of 23 toxigenic and 23 non-toxigenic strains were examined. All the toxigenic and 7 of the non-toxigenic strains had the same alleles at 16 enzyme loci, whereas the balance of the nontoxigenic strains had 9 distinct combinations of alleles. This study suggests that all of the toxigenic strains belong to a single clone, and that while some of the non-toxigenic isolates were related, most were of diverse origin.
多位点酶电泳用于检测从美国墨西哥湾沿岸及周边地区的患者和环境中分离出的霍乱弧菌O1产毒株和非产毒株之间以及它们内部的遗传关系。共检测了23株产毒株和23株非产毒株。所有产毒株和7株非产毒株在16个酶位点具有相同的等位基因,而其余非产毒株具有9种不同的等位基因组合。这项研究表明,所有产毒株属于单一克隆,并且虽然一些非产毒株具有相关性,但大多数来源各异。
