Morphology

Mesophilobacter marinus

CELLULAR

Staining	Gram negative
Morphology	Pleomorphic rods (0.6-0.6 x 1.0-2.0 um). Young culutres exhibit a plump form (0.8-1.0 x 1.5-3.0 um) and elongated cells (15 um). Old cultures exhibit coccoid cells (0.6-0.9 um diameter)
Motility	nonmotile
Specialized structures	no capsule

Division

COLONIAL

Solid surface

colonies on nutrient agar are usually circular but sometimes irregular, smooth, slightly convex, entire, glistening, opaque and pale yellowish brown

Liquid

moderate growth in nutrientbroth with a slight sediment
