Use of the Rapid STREP system for identification of viridans streptococcal species

A commercially available streptococcal identification system, Rapid STREP (API System S.A., Montalieu-Vercieu, France), was used to identify 119 viridans strains at the species level. A total of 92% of the strains tested were identified correctly with the Rapid STREP system, and 81% of the correct identifications were made at percentages of identification of 90 or greater. From these data it appears that the Rapid STREP system is a fairly accurate and rapid (24-h incubation) method for identifying species of viridans streptococci.
