Lancefield group D.
Gram-positive coccoid cells, grouped in pairs or chains. Non-spore-forming. Non-
motile.
Colonies are non-haemolytic, semitranslucent, round, entire, 0.25-0.55 mm in
diameter after 24 h growth on 5% sheep blood agar. Facultatively anaerobic. Growth
is enhanced in CO
2. Grows in 10% bile. Does not grow in conventional laboratory
liquid media with or without serum (brain-heart infusion broth (Oxoid), Todd
-Hewitt
broth (Oxoid), nutrient broth (Oxoid), fastidious anaerobe broth (LabM)). Grow at 37 ºC.
No growth at 10 ºC.
Isolated from dead grey seal (Halichoerius grypus) and dead porpoise (Phocoena phocoena), found on the east coastline of Scotland.
Isolated from the mesentery, kidney, pericardial fluid, peritoneal fluid and small intestine of a porpoise dead by severe enteritis and
peritonitis.
