title: Phenotypic and genotypic characterization of Enterococcus spp. of different origins.
abstract: Sixty-four strains of Enterococcus spp. of different origin were identified using traditional phenotypic, biochemical and cultural tests, together with molecular tests. API 20 STREP tests identified the species at a preliminary level, only one strain remaining unidentified. Strains belonging to the genus Enterococcus were tested with genus-specific primers, while species-level identification was carried out with the 16S-23S rDNA intergenic region (ITS) and species-specific primers for E. faecium and E. faecalis. Those strains found to be negative with the species-specific primers were subjected to 16S rDNA partial sequencing.
