ABSTRACT
An Australian diamond firetail finch died following the acute onset and development of severe diarrhea. The bird was purchased from a wholesaler and was housed in a pet store aviary with 12 other birds. Necropsy, histologic evaluation, and electron microscopic evaluation revealed organisms in the proventriculus (surface, ductal, and glandular epithelium) compatible in site of development, size, and morphology with Cryptosporidium spp. Lesions in the proventriculus were focal cuboidal metaplasia of glandular epithelial cells and deposition of amyloid in the perivascular interstitial tissues at the base of the glands. Amyloid also was present in the duodenum, liver, spleen, pancreas, and kidney. Inability to recover other organisms suggested that Cryptosporidium was the primary cause of diarrhea and death. The affected bird likely suffered dehydration as a result of acute gastrointestinal disturbance, concomitant with renal amyloidosis and urate nephrosis.
