Gram-positive, ovoid cocci, 0.7-0.9 x 0.5-1.1 µm, occuring single or grouped in pairs.
Non-spore-forming. Non-motile.
Colonies on TSYE agar under aerobic conditions after 48 h incubation at 37 ºC are
generally triangular or disc-shaped with regular edges, white,
smooth and reach 0.82-
2.75 mm in diameter.
Grows at 10 ºC and 40 ºC. Grows at pH 5-10. Facultatively
anaerobic.
L-lactic acid is produced from glucose (TSYE broth + 5g glucose / L).
Isolated from the digestive tract of wasp (Vespula vulgaris), Modrany, Czech Republic.
Susceptible to some cephalosporines, macrolides and some penicillin-derived antibiotics. Resistant to aminoglycosides,
fluoroquinolones, sulphonamides, mupirocine and metronidazole.
Undetermined.
