Cytomere

Last updated

Cytomeres are structures that are formed when the contents of a single large schizont are separated into multiple daughter cells, in the course of schizogony. [1]

Cytomeres are caused by complex invaginations of the surface of the schizont. They complete the budding process in the formation of large numbers of merozoites and are found in some species of sporozoans —including those of the Leucocytozoon genus—undergoing exoerythrocytic asexual division.

Invagination Process in embryonic development

In developmental biology, invagination is a mechanism that takes place during gastrulation. This mechanism or cell movement happens mostly in the vegetal pole. Invagination consists of the folding of an area of the exterior sheet of cells towards the inside of the blastula. In each organism, the complexity will be different depending on the number of cells. Invagination can be referenced as one of the steps of the establishment of the body plan. The term, originally used in embryology, has been adopted in other disciplines as well. There is more than one type of movement for invagination. Two common types are axial and orthogonal. The difference between the production of the tube formed in the cytoskeleton and extracellular matrix. Axial can be formed at a single point along the axis of a surface. Orthogonal is linear and trough.

<i>Leucocytozoon</i> genus of protists

Leucocytozoon is a genus of parasitic alveolates belonging to the phylum Apicomplexa. The parasites were first seen by Vasily Danilewsky in 1884 in blood from an owl. The genus was created by Ziemann in 1898. This taxon was revised by Berestneff in 1904 and then by Sambon in 1908.

Isosporiasis coccidiosis that involves infection of the epithelial cells of the small intestine with Cystoisospora belli, which results in nonbloody diarrhea with crampy abdominal pain, malabsorption and weight loss

Isosporiasis, also known as cystoisosporiasis, is a human intestinal disease caused by the parasite Isospora belli. It is found worldwide, especially in tropical and subtropical areas. Infection often occurs in immuno-compromised individuals, notably AIDS patients, and outbreaks have been reported in institutionalized groups in the United States. The first documented case was in 1915. It is usually spread indirectly, normally through contaminated food or water (CDC.gov).
