50 strains of viridans streptococci isolated from human material are identified by biochemical tests (bile esculin, Cl Na 6,5%, acid production from lactose, mannitol, sorbitol, inulin, arginine, esculin and starch hydrolysis; production of levan and dextran in sucrose media) Streptococcus salivarius and Streptococcus mitis are predominant species. Susceptibility to antibiotics was studied: 70% of viridans streptococci were susceptible to all antibiotics tested, high level resistance to aminoglycoside was not present. The only resistance observed were to tetracycline, macrolides and related drugs.
