Morphology
Cells are non-motile, non-spore-forming rods (0.6 × 2-3 µm) with parallel sides and rounded ends. Circular, entire, mucoid colonies develop on nutrient agar after incubation for 24 h; non-haemolytic on 5% (vol/vol) horse blood agar; on nutrient agar, colonies are non-pigmented and not fluorescent.
