[Phenotypical characterization of some strains of anginosus streptococci isolated from superficial face and neck abscesses].
The aim of the present study was to identify at species level and to characterize the strains of streptococci belonging to anginosus group isolated from 30 pus samples collected from patients with abscesses of fascial spaces of the face or neck. The identification of facultatively anaerobic Gram-positive cocci in chains at genus level was made by conventional diagnosis methods and at species level by the help of Rapid ID 32 STREP system. The cultural, biochemical and antigenic (limited at Lancefield Group identification by Slidex Strepto-Kit) characterization was performed in the mean time with the species identification. The anginosus streptococcal strains were isolated either in association with other bacteria or in pure culture and S. anginosus isolates clearly predominated. As expected, the anginosus streptococcal strains were found to be heterogeneous regarding the cultural, biochemical and antigenic features.
