Historical synonyms: Brevibacterium stationis (ZoBell and Upham 1944) Breed 1953,
Achromobacter stationis ZoBell and Upham 1944.
Gram-positive short rods, 0.6-1.0 µm in diameter, occur singly, in pairs and in ‘V’
forms and can be club shaped. Non-motile. Non-spore-forming.
Colonies on blood agar after 24 h are grey–white but become yellowish in time, 1 mm
in diameter and raised. Hemolysis is not produced. CAMP test is negative. Aerobic,
facultative anaerobic but poor or no growth under strictly anaerobic conditions. Grows
at/in : 25, 35 and 42 ºC. Grows in: 6-10% NaCl media.
Isolated from seawater, human infant stools and blood cultures. Strains are generally susceptible to a wide variety of antimicrobials.
Isolated from human infant stools and blood cultures.
