Gram-positive, straight or slightly curved rods, 1.4-1.7 x 3.1-6.3 µm, occur singly, in
pairs or in short chains. Motile by peritrichous flagella. Spores are oval, central or
subterminal, may swell the cell or occur as free spores. Sporulation occurs readily in
chopped-meat broth cultures incubated for 24 hours.
Surface colonies on blood agar plates are beta-hemolytic, 1-3 mm in diameter,
circular, low convex, opaque with translucent margins, white, shiny, and smooth, with
a coarse granular internal structure and an entire to scalloped margin. Cultures in
PYG broth are turbid with a ropy sediment and a pH of 5.3 after incubation for 5 days.
Moderately good growth in nutrient broth, mucoid sediment.
Optimum temperature for growth is 30 ºC. Grow at 25 ºC and at 45 ºC. Growth is
inhibited by 6.5% NaCl and 20% bile. Traces of gas may be detected in PYG deep
agar cultures. Products in PYG broth cultures include large amounts of butyric, acetic,
and isovaleric acids.
Isolated from soil and humus from Côte d’Ivoire. The type strain is susceptible to chloramphenicol, clindamycin, erythromycin,
penicillin G, and tetracycline.
Not pathogenic for guinea pigs or mice. Toxin is not produced.
