Multilocus sequence typing analysis of Klebsiella pneumoniae isolated from swine

A total of 86 strains Klebsiella pneumoniae isolated from swine were collected to analysis the molecular genetic characteristic by multilocus sequence typing (MLST). The eURST software was used to evaluate the results of MLST. The results indicated that all isolates clustered into 14 ST types(STs). ST106 (including 3 strians) and ST23 (including 2 strians) were single branch. Other 12 ST types belong to the CC258 clonal complex. This study showed that klebsiella pneumoniae isolated from swine in this region has some genetic diversity and the main types were ST258 clone complex, it may be transfered between swine and human.
