説明

The biochemical and serological characteristics of Streptococcus salivarius were investigated. Strains used included S. salivarius ATCC 7073, ATCC 9222, ATCC 9758, ATCC 9759, ATCC 13419, ATCC 25975, ATCC 27945 and ATCC 31067 as reference strains, and 72 oral isolates from healthy adults and 6 oral isolates from patients with Behcet's disease. Eight reference strains and all except 4 of our 78 isolates of S. salivarius were biochemically classified into 4 biotypes, A to D, according to their carbohydrate fermentation profiles. S. salivarius was also serologically heterogenous, and 4 serotypes were indentified by immunodiffusion in agar gel with antigens extracted with nitrous acid by Kholy's method and anti-sera against whole cells of S. salivarius. Although 8 reference strains could be classified as each of 4 serotypes, all of our isolates belonged to either serotype II or III and none belonged to serotype I or IV.<BR>This study also showed that biochemical and serological characteristics of S. salivarius isolates from patients with Behcet's disease were not distinct from them of S. salivarius isolates from healthy adults, and it seemed that S. salivarius isolates from the two origins were indistinguishable.
