Occurrence of Sarcocystis falcatula in captive psittacine birds in Brazil.

Abstract

Thirty-eight captive psittacine birds housed in a bird park in Foz do Iguaçu, Parana, Brazil, died within a 15-month period as a result of infection with Sarcocystis falcatula. Although fatalities affected 16 species of psittacine birds, mortality was highest in Old World species, which were most susceptible to the pulmonary form of sarcocystosis. Along with the pathologic findings of this disease outbreak, a review of the pathophysiology of sarcosporidiosis is presented.
