Schizont bodies reminiscent of those described by Wenyon from Baghdad sparrows were found in the liver and lungs of an Israeli house sparrow ( Passer domesticus biblicusHartert 1904) infected with Haemoproteus passeris Kruse, 1890. All observed schizonts were composed of packed assemblages of walled compartments, each holding a differentiating schizogonic body. The schizogonic bodies in the various compartments demonstrated sequential stages in the differentiation process from a compact multinucleate cytoplasmic mass to massive formation of multiple merozoites. Young non-differentiated schizont assemblages reached 0.2 x 0.25 mm in size and the fully differentiated ones, containing merozoites, were double or triple that. Among species of Haemopterus, division to compartmented and single-plasmodium schizonts could not be associated with any recognized generic or infrageneric division. Moreover, in some species of Haemoproteus, both types of schizogony co-existed.
在一只感染了1890年克鲁斯氏血变原虫(Haemoproteus passeris)的以色列家麻雀(Passer domesticus biblicus Hartert,1904)的肝脏和肺中,发现了类似于温扬描述的来自巴格达麻雀的裂殖体。所有观察到的裂殖体均由充满壁状隔室的集合体组成,每个隔室都容纳一个正在分化的裂殖生殖体。不同隔室中的裂殖生殖体展示了从紧密的多核细胞质团到大量形成多个裂殖子的分化过程中的连续阶段。未分化的年轻裂殖体集合体大小达到0.2×0.25毫米,而含有裂殖子的完全分化的裂殖体则是其两倍或三倍。在血变原虫属物种中,分为隔室化裂殖体和单疟原虫裂殖体与任何公认的属或亚属分类无关。此外,在一些血变原虫物种中,两种类型的裂殖生殖共存。
