Gram-negative, motile rods. Produce peritrichous flagella when grown at 22 ºC; less
motile at 36 ºC. Is more active biochemically at 25 ºC.
motile at 36 ºC. Is more active biochemically at 25 ºC.
Grows slowly on nutrient agar, forming colonies only about 0.1 mm at 24 h, 36 ºC;
colonies are five times larger when grown at 30 ºC for 24 hours. Grows on laboratory
media including MacConkey agar.

Isolated from surface waters,intestinal tract of freshwater salmonid fish & human feces. Resistant to penicillin, ampicillin & cephalothin.
None, uncertain clinical significance. No evidence that it is a pathogen for plants or animals.
