Gram-positive cocci growing in pairs 0.62-0.78 x 0.91-1.0 µm
Non-motile.
Non-motile.
Colonies on blood or MRS agar are 1–2 mm in diameter after 5 days of incubation,
white to light grey and translucent. Alpha-haemolytic 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 °C but no growth is observed at 45 °C. 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.
