Gram-negative, straight bacilli, 1.0 x 2.0-3.0 μm, usually motile by peritrichous flagella
(nonmotile strains may occur). No capsule production.
(nonmotile strains may occur). No capsule production.
Growth occurs on usual media, producing small colonies (0.5-1.0 mm in diameter)
after 24 h incubation. Optimum temperature, 37 ºC. Facultatively anaerobic.
