Identification of viridans streptococci isolated from clinical specimens

Abstract

Of 532 strains of viridans streptococci isolated from clinical (human) specimens, 517 were identified by using a scheme based on the work of Facklam. The strains were distributed among 9 of the species described by Facklam and an additional group of physiologically homogeneous streptococci not recognized in Facklam''s scheme. The method for identification involves a battery of 10 tests that employ both conventional media and commercially prepared disks. The identification of most of the isolates was accomplished within 48 h.
