[Use of the Streptotest for identification of enterococci and viridans-type streptococci].

Abstract

The new identification system STREPTOtest (fy. Lachema, Brno) was evaluated. A total 118 well-known strains of genus Enterococcus, Streptococcus, Aerococcus, Stomatococcus and Gemella were tested. The STREPTOtest system rapidly and reliably distinguished genus Enterococcus from genus Streptococcus. This method identified correctly to the species level 65.9% of enterococci strains and 52.5% of streptococci strains. The STREPTOtest was used for identification of A. viridans and S. mucilaginosus and it was possible to separate these strains from similar ones. A new differentiation chart for identification of all 13 recently described enterococcal species was proposed.
