Multilocus sequence typing of Enterococcus faecalis from vegetable foods reveals two new sequence types.

A collection of 16 isolates of Enterococcus faecalis from different vegetable foods were characterized by multilocus sequence typing (MLST). One isolate belonged to sequence type (ST) 9 of the previously described clonal complex 9, which is frequently associated with hospital environments. The rest of the isolates were grouped into two new STs named 168 and 169. ST168 represented a singleton clone that included 14 isolates and seemed to be the predominant type among E. faecalis from vegetable samples. ST168 was closely related to ST72, differing only by one allele type. Singleton ST169 was not related to any of the previously described STs.
