A wild-caught adult female southern water snake (Nerodia fasciata pictiventris) did poorly in captivity. A peripheral blood-film examination demonstrated numerous hemogregarines characterized as fusiform nondividing intraerythrocytic gametocytes. Xenodiagnostic typing in laboratory-reared mosquitoes demonstrated the parasite to be of the genus Hepatozoon. Gross and histopathologic examination of the liver demonstrated numerous granulomas centered on groups of one to six Hepatozoon sp. meronts, an unusual finding in naturally infected wild-caught snakes.
一条野生捕获的成年雌性南方水蛇（Nerodia fasciata pictiventris）在圈养环境中状况不佳。外周血涂片检查显示有大量血簇虫，其特征为梭形、非分裂的红细胞内配子体。在实验室饲养的蚊子中进行异种诊断分型表明，该寄生虫属于肝簇虫属。对肝脏进行大体和组织病理学检查发现，有许多肉芽肿，其中心为一至六个肝簇虫属裂殖体组成的群体，这在自然感染的野生捕获蛇中是一个不寻常的发现。
