Gram-negative rods. Non-spore-forming.
Colonies are moist, showing a metallic sheen. Grows on MacConkey agar and on
BCSA where and some strains turn the medium alkaline. Growth is observed at 30
and 37 and 42 ºC. Most strains are yellow-pigmented and haemolytic. Aerobic.

Isolated from clinical samples, but also from environmental samples, from a Sargasso Sea sample, but which probably represented
a contaminant. Isolated as contaminant in nasal spray in USA and as contaminant in a water reservoir supplying a renal dialysis
machine in Brazil.

Recovered from milk of a sheep with mastitis in Spain during an outbreak in 1999-2000.

Positive results for esculin hydrolysis, gelatin liquefaction, beta-galactosidase, lysine
decarboxylase, oxidase, acid production from: adonitol, glucose, sucrose, maltose,
lactose and xylose.
Can assimilate glucose, L-arabinose, D-mannose, D-mannitol, N-acetylglucosamine, D-gluconate, caprate, adipate, L-malate, citrate
and phenylacetate.
Negative results for arginine dihydrolase, ornithine decarboxylase, tryptophanase and urease. No assimilation of maltose.
Variable results for nitrate reduction.
