Sarcocystis falcatula is a protozoan parasite which obligatorily alternates its definitive host, the opossum (Didelphis virginiana), and a uniquely wide range of avian intermediate hosts. The disease produced by this coccidian parasite in intermediate hosts was studied in the budgerigar bird (Melopsittacus undulatus). The ultrastructure of pulmonary sporozoites, meronts and merozoites of this Sarcocystis species is described. Early schizogony occurs progressively in pulmonary capillary and in venular and venous endothelial cells.
猫狐囊尾蚴是一种原生动物寄生虫，其终末宿主为负鼠（弗吉尼亚负鼠），中间宿主为种类独特且范围广泛的鸟类，必须在这两类宿主之间交替寄生。在虎皮鹦鹉（虎皮鹦鹉）中研究了这种球虫寄生虫在中间宿主体内引发的疾病。描述了该种囊尾蚴的肺内子孢子、裂殖体和裂殖子的超微结构。早期裂体生殖在肺毛细血管以及小静脉和静脉内皮细胞中逐步发生。
