Gram-positive cocci growing in pairs 0.62-0.78 x  0.91-1.0 µm. Nonmotile.
Colonies on blood or MRS agar are 1-2 mm in diameter after 5 days of incubation,
white to light grey and translucent. Alpha-hemolytic bovine blood agar. Strains grow
slowly on azide containing enterococcal selective media as typical, maroon
colonies and cause blackening of bile-aesculin agar. Grow well at 10 and 37 ºC but
no growth is observed at 45 ºC. All strains grow well in the presence of 2 or 4%
NaCl. Some strains grow in 6.5% NaCl media. No growth in 10% NaCl.
Isolated from broiler meat and canine tonsils.
Unknown. It is possible that E. hermanniensis occurs in the gastrointestinal tract of broiler chickens and dogs, which has resulted in
the contamination of poultry products and its occurrence in canine tonsils.
