Gram-negative rods, 0.9 x 1.5-3.0 μm, occuring singly or in pairs. Motile. Non-spore-
forming.
forming.
Colonies are light beige, circular, 1-1.2 mm in diameter, convex and with entire
margins After 24-48 hour incubation on nutrient agar at 26-28 ºC. Does not produce
fluorescent pigment on King’s medium B. Growth in yeast salt and liquid 523 medium
(Schaad et al., 2001) occurs at 36 ºC, but not at 39 ºC. Able to grow in 5% (w/v) NaCl.
Facultatively anaerobic.
