It is common for pure cultures of vibrios to produce multiple colony morphologies (as many as 5), best seen on blood agar.
Variations in morphology include smooth, rough, convex, flat spreading, and compact in various combinations.
McConkey: growth, non lactose fermenter
TCBS: yellow colonies
(Yellow colonies may convert to green if plates are examined after more than 24 hours or are refrigerated after incubation.)
BBAØ: growth
motility: can swarm on solid media by production of numerous lateral flagella
