Leucocytozoon-like infection in parakeets, budgerigars and a common buzzard.
The gross and histological lesions of a protozoan infection, possibly caused by Leucocytozoon, in parakeets (genera Neophema and Cyanoramphus), budgerigars (Melopsittacus undulatus) and a wild buzzard (Buteo buteo) are described. The infection appears not to have been identified before in budgerigars in Great Britain, and in its chronic form resulted in vomiting and wasting. The possible identity of the parasite and the epidemiological factors are considered.
