| application of a multilocus variable number of tandem repeats analysis to regional outbreak surveillance of enterohemorrhagic escherichia coli o157:h7 infections. | a total of 18 strains of ehec o157:h7 were isolated from distinct cases in akita prefecture, japan from july to september 2007. the genetic relatedness of these isolates was investigated by performing a multilocus variable number of tandem repeats analysis (mlva) and a pulsed-field gel electrophoresis (pfge) analysis using xbai. the pfge analyses allowed us to group these 18 isolates into three major clusters. the mlva results correlated closely with those obtained by pfge, although some variant ... | 2011 | 21266759 |
