Three cases of infection by haemophilus‐like bacteria in psittacines

Summary The clinical manifestations of three cases of infection with NAD (V‐factor)‐requiring Haemophilus‐like bacteria in psittacines are described. Case 1 involved members of the Platycercus family and produced mainly respiratory signs. In case 2 only conjunctivitis was seen among cockatiels. The third case was a hand‐reared African grey parrot which developed a peracute septicaemia. The Haemophilus‐like bacteria isolated from the three cases differed from each other as well as from the known avian NAD‐requiring Haemophilus and Pasteurella species.
