Occurrence of putative pathogenicity islands in enterococci from distinct species and of differing origins

Abstract

Enterococci isolated from ewe's milk and cheese, clinical isolates of human and veterinary origins, and reference strains obtained from culture collections were screened for the occurrence of putative pathogenicity island (PAIs). Results obtained after PCR amplification and hybridization point toward PAI dissemination among enterococci of diverse origins (food/clinical) and species (Enterococcus faecalis/non-E. faecalis).
