Phylum Actinobacteria, Class Actinobacteria, Subclass Actibacteridae, Order Actynomycetales, Suborder Corynebacterinae, Family
Corynebacteriaceae, Genus Corynebacterium, Corynebacterium felinum Collins, Hoyles, Hutson, Foster and Falsen 2001.
Description is based on a single isolate.
Gram-positive diphtheroid rods. Non-spore-forming. Non-motile. Tuberculostearic
acid is absent. Mycolic acids are present.
Cultured on Columbia blood agar base supplemented with 5% defibrinated sheep
blood at 37 ºC in air plus 5% CO2. Non-haemolytic. Facultatively anaerobic.
Isolated from a Scottish wild cat that had died from feline influenza. Habitat is unknown.
