title: Cryptosporidiosis in domestic birds.
abstract: From March to June 1982, three cases of avian cryptosporidiosis were encountered in chickens, ducklings, and canaries. The bursa of Fabricius of chickens and ducklings were the main target organs and the agents were found to attach the microvillus border of the plical epithelium. In canaries, the parasites adhered to the microvillus border of mucosal epithelium of the proventriculus. Diagnoses were based on the microscopic pathology, the morphology of the parasites, and the type of attachment to epithelium. This represents the first authenticated evidence of cryptosporidial infection in Taiwan.
