The schizont's membrane then invaginates in deep furrows cleaving the parasite into pseudo\u2010cytomeres. thereby increasing the area of membrane available for differentiation. Signs of differentiation appear under this membrane as soon as it is formed. Rhoptries and polar rings develop in the region of the dense accumulations, the cytoplasm containing these structures begins to elevate, and each evagination differentiates into a merozoite. When the merozoite is half\u2010formed, the cytostome appears, then dense bodies at the apex of the organism, and finally a spherical body intimately associated with a mitochondrion. These merozoites of <jats:italic>Haemoproteus<\/jats:italic> are assumed to be the forms that penetrate erythrocytes and become gametocytes. They contain the same organelles as merozoites of <jats:italic>Plasmodium.<\/jats:italic> However, the merozoites of <jats:italic>Haemoproteus<\/jats:italic> are oval like the erythrocytic merozoites of <jats:italic>Plasmodium<\/jats:italic> rather than elongate like the exoerythrocytic merozoites. This body shape may be a generic characteristic or it may indicate a structural difference between exoerythrocytic merozoites and merozoites that infect erythrocytes.<\/jats:p><jats:p>When the merozoites of <jats:italic>Plasmodium, Haemoproteus<\/jats:italic> and <jats:italic>Leucocytozoon<\/jats:italic> are compared, the first 2 genera appear closely related, but <jats:italic>Leucocytozoon<\/jats:italic> seems very different. Perhaps it should not be included within the Haemoproteidae.<\/jats:p>","DOI":"10.1111\/j.1550-7408.1971.tb03397.x","type":"journal-article","created":{"date-parts":[[2007,5,14]],"date-time":"2007-05-14T00:42:04Z","timestamp":1179103324000},"page":"679-686","source":"Crossref","is-referenced-by-count":13,"title":["The Fine Structure of Differentiating Merozoites of <i>Haemoproteus columbae<\/i> Kruse*"],"prefix":"10.1111","volume":"18","author":[{"given":"PHYLLIS CLARKE","family":"BRADBURY","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BETTY B.","family":"GALLUCCI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,4,30]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"605","article-title":"The sporogony of","volume":"17","author":"Adie H.","year":"1924","journal-title":"Haemoproteus columbae.
