macrogametocyte

 [mak″ro-gah-me´to-sīt]

macrogametocyte

/mac·ro·ga·me·to·cyte/ (-gah-mēt´ah-sīt)
1. a cell that produces macrogametes.
2. the female gametocyte of certain Sporozoa, such as malarial plasmodia, which matures into a macrogamete.

macrogametocyte

[-gamē′təsīt]
Etymology: Gk, makros + gamete + kytos, cell
an enlarged merozoite that undergoes meiosis to form the mature female gamete during the sexual phase of the life cycle of certain thallophytes and sporozoa, specifically the malarial parasite Plasmodium. Macrogametocytes are found in the red blood cells of a person infected with the malarial parasite, but they must be ingested by a female Anopheles mosquito to complete the maturation process and develop into macrogametes.

Host cell infected with three parasites (arrowhead); 5, microgamont (MIC), macrogamont (Ma) and mature meronts (Me); 6, mature microgamonts (MM), attached to the underlying epithelium via a stalk-like structure (arrowhead), shedding microgametes, note disappearance of the parasite membrane and fragmentation of its surface; 7, macrogamontes (Ma) with wall-forming bodies (WF).
Scale bar = 1um; 13, young macrogamont with wall- forming bodies 1 (WF1) and 2 (WF2) and vacuoles (V).
Macrogamonts were recognized by their nuclei each with a nucleolus and characterized by wall-forming bodies 1 and 2.
Mature macrogamonts with wall- forming bodies measured 13.
Young macrogamonts were surrounded by a parasitophorous vacuole and filled with small granules and large spherical structures surrounded by a single unit membrane.
Mature macrogamonts and zygotes were characterized by a huge number of amylopectin granules scattered in their cytoplasm together with less number of lipid vacuoles and numerous canaliculi.
Macrogamonts are smaller than those described in C.
In the mature macrogamont, the nucleus develops funnel-formed extensions into the cell wall (wall-forming bodies II), through which microgametes can penetrate.
