Neisseria animaloris, formerly named CDC group EF-4a, is a gram-negative coccoid rod. The bacterium is a commensal of the upper respiratory tract of cats and dogs, and they may cause pulmonary infections in cat.[1] In humans Neisseria animaloris have been reported to cause wound infection after animal bites but also chronic otitis media, bacteremia and endophtalmitis.[2][3][4]

On blood agar colonies are haemolytic yellowish white, opaque, shiny and smooth. They are oxidase and catalase-positive but indol negative and as a distinct characteristic N amimaloris is arginine dihydrolase positive. Unlike most other Neisseria species N animaloris grows on McConkey agar.[5][6]
