Identification of Staphylococcus Species with the VITEK 2 System: the Case of Staphylococcus hominis

We read with interest the paper by Layer et al. regarding the identification of staphylococci with automated systems including VITEK-2 (bioMerieux, Marcy l'Etoile, France) (6). Of 86 strains analyzed in their study, 4 were Staphylococcus hominis and all were correctly identified by the colorimetric ID-GP VITEK-2 cards. Identical results have been reported in recent studies evaluating 13 and 14 S. hominis isolates (3, 7).
