摘要

The presentation is a retrospective survey of the histologic lesions in the proventriculus and ventriculus of pet birds. The etiologies cover inflammatory, trauma, neoplasia, degenerative processes, and disease agents such as viruses, yeast and fungus, bacteria, protozoa, and metazoan parasites. The more common lesions are briefly discussed. The 2 groups of pet birds examined for the study include psittacines (n=1429) and passerines (n=211). The psittacine group is comprised of Amazons (Amazona species) (n=72), Brotogeris species (n=17), budgerigars (Melopsittacus undulatus) (n=175), caiques (n=10), cockatiels (Nymphicus hollandicus) (n=204), cockatoos (Cacatua species) (n=l 34), conures (Aratinga species) (n= 119), lories and lorikeets (n= 16), lovebirds (Agapornis species) (n=61), macaws (Ara species) (n=285), parakeets of the Australian/Asian regions (n=62), African grey and timneh parrots (Psittacus erithacus) (n=166), Eclectus parrots (Eclectus roratus) (n=66), and parrotlets (Forpus species)(n=41). The passerine species include canaries (n=76) (Serinus canarius) and finches (n=135).
