Toxoplasma (CMIA)

Toxoplasma gondii inonzi intracellular parasite, inonziwo trisomia.Iyo parasitizes mumasero uye inosvika munzvimbo dzakasiyana dzemuviri nekuyerera kweropa, ichikuvadza uropi, moyo uye fundus yeziso, zvichikonzera kuderera kwekudzivirira kwevanhu uye zvirwere zvakasiyana.Iyo inosungirwa intracellular parasite, Coccidia, Eucoccidia, Isosporococcidae uye Toxoplasma.Hupenyu hunoda mauto maviri, muenzi wepakati anosanganisira zvinokambaira, hove, zvipembenene, shiri, mhuka dzinoyamwisa uye dzimwe mhuka nevanhu, uye mugadziri wekupedzisira anosanganisira katsi nemhuka.

Toxoplasma gondii ndeye coccidia, toxoplasma mhuri uye toxoplasma.Hupenyu hunoda mauto maviri, muenzi wepakati anosanganisira zvinokambaira, hove, zvipembenene, shiri, mhuka dzinoyamwisa uye dzimwe mhuka nevanhu, uye mugadziri wekupedzisira anosanganisira katsi nemhuka.Hupenyu hweToxoplasma gondii hunogona kugoverwa muzvikamu zvishanu: tachyzoite stage (trophozoite): kukurumidza kupatsanurwa mumasero ane nucleated kuti atore cytoplasm yehondo yose, inonzi pseudocyst;bradyzoite nhanho: kunonoka kuwedzera mumadziro e cyst yakavanzwa nemuviri, inonzi cyst, ine mazana ebradyzoites;Schizosome stage: Iko kusanganiswa kwemerozoites inoumbwa nekupararira kwebradyzoites kana sporozoites mumasero maduku eepithelial ekitsi;Gametophytic nhanho: ma gametes makuru (echikadzi) uye madiki gametes (murume) anoumba zygotes mushure mekusangana uye pakupedzisira anokura kuita oocysts;Sporozoite nhanho: inoreva kukura uye kuberekana kwesporophyte muoocyst, ichiita sporangia mbiri, uye ipapo imwe neimwe sporangia inokura kuita ina sporozoites.Matanho matatu ekutanga ndeekusaberekana, uye nhanho mbiri dzekupedzisira kuberekana.

Toxoplasma gondii inokura mumatanho maviri: the extraintestinal stage uye intraintestinal stage.Iyo yekutanga inokura mumaseru eakasiyana epakati mauto uye makuru tishu ezvirwere zvinotapukira zvinouraya.Iyo yekupedzisira yakagadzirwa chete mu epithelial masero ekupedzisira host intestinal mucosa.
