Negative results for indole production, nitrate reduction, PNPG, urease and glucose fermentation.
No assimilation of D-aspartic acid, adipate, Tween 40, glycyl-L-proline, D-fructose-6-phosphate and D-malic acid.
Variable results for the assimilation of adipate, phenylacetate, oxidation to bromo-succinic acid and formic acid and resistance to 8%
NaCl. The rest of the characteristics tests are negative or weak.

Gram-negative rods, 0.8-1.1 x 2.0-3.2 µm. Motile by polar flagella. Non-spore-forming.
Colonies on Luria Bertani agar are circular, convex with entire edges, smooth, cream
coloured of 0.5-1.5 mm diameter after incubation at 30 ºC for 24 h. Beta-hemolytic.
Growth occurs at temperature range 4-30 ºC, at pH 7-9 and in 0-6% (w/v) NaCl.
Fluorescent pigment produced, but not pyocyanin. Aerobic.

Isolated from fish farm waters, rainbow trout (Oncorhynchus mykiss), river water, industrial water, human lung tissue.
Resistant to 1% sodium lactate, troleandomycin, lincomycin, vancomycin, nalidixic acid, aztreonam, fusidic acid, rifamycin SV,
guanidine HCl, tetrazolium violet, lithium chloride, sodium butyrate, minocycline, nioproof 4, tetrazolium blue, potassium tellurite and
sodium bromate.

No pathogenicity against fishes has been demonstrated so far. However, 1 strain was isolated from a human lung specimen, and 8
were isolated from water, yolk-sacs, and alevin surfaces. The sequenced strains can produce a type VI secretion system and harbour
genes for the synthesis of effectors, haemolysin, efflux pumps and alginate. These pathogenicity traits, point to the possibility of
pathogenicity but also to survival mechanisms in the environment.
