Tanasupawat et al. 2008.
According to Shewmaker Patricia Lynn et al. 2011, Enterococcus thailandicus Tanasupawat et al. 2008 is a later subjective synonym
of Enterococcus sanguinicola Carvalho et al. 2008, but the name E. sanguinicola is not validly published.
Gram-positive cocci, non-spore-forming, spherical or ovoid, 0.5 – 1 μm in diameter,
arranged in pairs or in chains. Nonmotile.
Colonies are circular, raised or low-convex with entire margins, and non-pigmented.
Weak hemolisis on blood agar. Facultatively anaerobic. Red colonies appear on
Slanetz–Bartley agar. Grows on kanamycin aesculin azide agar. Grow in 2-6.5% NaCl
medium; weak growth in 8% NaCl. Growth is positive at 15 - 45 ºC and pH 5.0-9.6.
Niacin, calcium pantothenate and folic acid are required for growth. No acidification,
coagulation, reduction or liquefaction in litmus milk.
Enterococcus thailandicus strain was isolated from fermented sausage (‘mum’) in Thailand, and from beavers intestine in Poland.
E. sanguinicola strain was isolated from human blood sample.
