Gram-negative rods, 0.5 x 1.0 μm. Non-spore-forming. Motile.
Colonies are beige, translucent and shiny with entire edges, approximately 1 mm in
diameter within 24 h of incubation. Good growth occurs on R2A agar, TSA, PYE agar
and nutrient agar at 25-30 ºC. Grows on TSA at 15-37 ºC, but not at 10 or 42 ºC.
Grows between pH 5.5-11.0, but not at pH 5.0 or pH 11.5.
Isolated from the skin of the medical leech Hirudo verbana in the Leech Breeding Station, Biebertal, Germany.
Undetermined.
