| Type Strain: | ATCC 33658 = NCTC 12959 | ||||||||
| Macromorphology (smell):
| Grey-white translucent colonies (diameter 1-3 mm) with a buttery consistency without hemolysis, produces a brown water soluble pigment on agar containing tyrosine or phenylalanine. Gives hemolysis on ox blood agar. | ||||||||
| Micromorphology: | Nonmotile rods with rounded ends, sometimes coccoid, sometimes in pairs or short chains. | ||||||||

| Spec. Char.: | Temperature optimum: 25°C, no growth at 37°C | ||||||||
| Special Media:
| A. salmonicida subsp. salmonicida is growing well on purple agar, but does not ferment lactose. However, this bacterium produces redbrownish and watersoluble pigmen, which can be seen on the purple agar plate. | ||||||||
