Toxoplasma (CMIA)

Toxoplasma gondii ni parasite idasanzwe, nanone yitwa trisomia.Ihindura parasile kandi igera mu bice bitandukanye byumubiri hamwe namaraso, yangiza ubwonko, umutima hamwe ninkunga yijisho, bigatuma igabanuka ryubudahangarwa bwabantu nindwara zitandukanye.Ni parasite idasanzwe, Coccidia, Eucoccidia, Isosporococcidae na Toxoplasma.Uruzinduko rwubuzima rusaba abashyitsi babiri, uwakiriye hagati arimo ibikururuka hasi, amafi, udukoko, inyoni, inyamaswa z’inyamabere n’izindi nyamaswa n’abantu, kandi uwakiriye nyuma arimo injangwe n’imigozi.

Toxoplasma gondii ni iyitwa coccidia, umuryango wa toxoplasma na toxoplasma.Uruzinduko rwubuzima rusaba abashyitsi babiri, uwakiriye hagati arimo ibikururuka hasi, amafi, udukoko, inyoni, inyamaswa z’inyamabere n’izindi nyamaswa n’abantu, kandi uwakiriye nyuma arimo injangwe n’imigozi.Ubuzima bwinzira ya Toxoplasma gondii irashobora kugabanywamo ibyiciro bitanu: icyiciro cya tachyzoite (trophozoite): igabana ryihuse mu ngirabuzimafatizo kugira ngo zifate cytoplazme yabakiriye bose, bita pseudocyst;icyiciro cya bradyzoite: gukwirakwira buhoro murukuta rwa cyst rwasohowe numubiri, rwitwa cyst, rurimo amagana ya bradyzoite;Icyiciro cya Schizosome: Ni uguteranya merozoite iterwa no gukwirakwiza bradyzoite cyangwa sporozoite mu ngirabuzimafatizo ntoya zo mu nda;Icyiciro cya gametophytike: imikino nini (igitsina gore) na gametes ntoya (igitsina gabo) ikora zygote nyuma yo gusama hanyuma amaherezo ikura muri oocysts;Icyiciro cya Sporozoite: bivuga iterambere no kubyara sporofitike muri oocyst, bigakora sporangia ebyiri, hanyuma buri sporangia ikura muri sporozoite enye.Ibyiciro bitatu byambere ni imyororokere idahuje igitsina, naho ibyiciro bibiri byanyuma ni imyororokere.

Toxoplasma gondii ikura mubyiciro bibiri: icyiciro cyo hanze nicyiciro cyimbere.Iyambere ikura mu ngirabuzimafatizo zinyuranye ziciriritse hamwe nuduce twinshi twindwara zanduza.Iyanyuma yateye imbere gusa muri epithelial selile yanyuma ya mucosa yo munda.
