Acute generalized sarcocystosis was diagnosed in a capercaillie (Tetrao urogallus) from Finland. Microscopic lesions were seen in the heart, lungs, spleen, liver, and brain. Protozoa were found in all organs, especially in the lungs and spleen. Only asexual stages were observed. The parasite divided by endopolygeny. Schizonts were usually 10 microm wide and up to 55 microm long. Merozoites are 3-4 microm long and 1.5-2.0 microm wide. Sarcocysts and sexual stages are unknown. The parasite was considered to be a species of Sarcocystis with an unknown life cycle. This is the first report of acute sarcocystosis in capercaillie from Finland.
在一只来自芬兰的黑琴鸡（Tetrao urogallus）身上诊断出急性全身性肉孢子虫病。在心脏、肺、脾脏、肝脏和大脑中发现了微观病变。在所有器官中都发现了原生动物，尤其是在肺和脾脏中。仅观察到无性阶段。寄生虫通过内多殖进行分裂。裂殖体通常宽10微米，长可达55微米。裂殖子长3 - 4微米，宽1.5 - 2.0微米。肉孢子囊和有性阶段未知。该寄生虫被认为是一种生命周期未知的肉孢子虫属物种。这是芬兰黑琴鸡急性肉孢子虫病的首次报告。
