Member of the "Mutans group".
Gram-positive, non-motile cocci, grouped in long chains.
Regular, under 0.5 mm in diameter, non-pigmented, translucent colonies. On blood
agar colonies are surrounded by zones of alpha-hemolysis. Growth at 37 °C. Aerobic,
facultatively anaerobic. Growth enhanced by incubation in a 5% C02-supplemented
atmosphere. Media: Trypticase soy agar with 5% sheep blood, Brain heart infusion
agar or broth.
Isolated from the genital tract of swine (vagina).
Unknown (none).
