This report describes acute interstitial pneumonitis due to an apicomplexan parasite with schizogony in endothelial cells of pulmonary vessels accompanied by early and metrocyte stages of sarcocysts in the heart of a thick-billed parrot (Rhynchopsitta pachyrhyncha). The pattern of this disease is similar to that of the acute phase (approximately 10-15 days postinoculation) of experimental infections of budgerigars, Melopsittacus undulatus, with high doses of sporocysts of Sarcocystis falcatula.
本报告描述了一只厚嘴鹦鹉（Rhynchopsitta pachyrhyncha）心脏中出现的急性间质性肺炎，病因是一种顶复门寄生虫，其在内皮细胞中进行裂体生殖，同时伴有肉孢子虫早期和滋养体阶段，肺血管内皮细胞中可见裂殖体。这种疾病的模式与虎皮鹦鹉（Melopsittacus undulatus）经高剂量法氏囊肉孢子虫孢子囊实验感染急性期（接种后约10 - 15天）的模式相似。
