title: Schizogonic stages of Haemoproteus from Wenyon's Baghdad sparrows are also found in Passer domesticus biblicus in Israel.
abstract: 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.
