Gram-variable rods, 0.5–0.7 x 2.0–3.0 μm. Produce ellipsoidal spores in swollen
sporangia. Spores have a ornamentation similar to that of honeycomb.
Colonies are translucent, white with a central brown spot, convex and 1-3 mm in
diameter in 48 h at 37 ºC on YED (yeast extract / glucose) medium. Aerobic growth.
Chemo-organotrophic. Optimum growth temperature 37 ºC, no growth at 50 ºC. Grow
in 2%, weak growth in 5% NaCl media. Grow at pH 5.6; optimum pH 7.0.
Isolated from old and recent cow dung in Salamanca, Spain, and from rectal samples of a cow in Leon, Spain.
Susceptible to erythromycin, penicillin, oxacillin, bacitracin, piperacillin, gentamicin and cefoxitin. Resistant to tobramicin, cephalexin
and dibekacin.
Undetermined.
