Plasmodium falciparum - kunobva achinyengera chirwere

Mumwe kubva chirwere chakakomba zvikuru, izvo zvinokanganisa munhu Denda - ndiwo marariya. A zana apfuura, iye anotora upenyu zviuru vomunyika yedu - ive mushonga zvakabatsirawo marariya hariko. Zvisinei, mune Soviet nguva marariya akaunzwa kudzora uye kunyange kuderedza kuti nyaya imwe chete, iyo pakarepo akasvika pasi pfungwa utano nenyanzvi.

Plasmodium falciparum, inova causative mutumwa chirwere chiri pakubhadhara anoverengeka. Vose vari semhosva "tupukanana." Mumuviri womunhu anogona parasitize utachiona vatatu-zuva mana-zuva, uyewo dzinopisa marariya. Sezvo rudzi voga utachiona hwakakura ovalemalyarii, izvo zvinowanikwa Central Africa. mhando dzose idzi vane upenyu kutenderera yakafanana, yakafanana chimiro, chete mamwe mashoko akasiyana.

The malarial chisvetasimba iri kubva Umhutu kuti kutapura munhu kuburikidza ikaruma. The umhutu mate utachiona hwakakura iri pasi sporozoite. Pamwe chete Plasmodium falciparum ropa riyerere anopinda chiropa rinenge apo rinokosha Danho upenyu chisvetasimba - schizogony. Muvanhu, ichi nguva rinobatana kukura Plasmodium incubation munguva chirwere. In chiropa, sporozoites ose schizonts kuva - vanokura kukura uye kushingaira ive zviuru masero mwanasikana. Saka muna neutachiona chiropa masero vanoparadzwa, kupa chaizvo zviratidzo. Pashure danho schizogony tupukanana dziri muropa, sezvamakaropafadzwa danho kunosvika pachiyero masero eropa - erythrocytic schizogony. Saka Plasmodium falciparum absorbs Chizenga (puroteni chezvinonhuwira ayo globin) uye anoramba asexual kubereka. Izvi kutenderera zvinogona kudzokororwa muropa kakawanda. Izvi zvinowanzoitika ose matatu - mazuva mana, zvichiratidza kuti kuibvisa itsva batch mangé plasmodium. Anokosha, zvakasara pamusoro Chizenga pachahwo simba muchetura. Kana matsvuku eropa watsemuka uye marariya tupukanana muropa anobuda, chinobuda nacho uye vakasununguka anokosha. Panguva ino, vanhu vanotsigira chisvetasimba anonzwa tichibatwa malarial nefivhiri. Wakakura zvikuru chiratidzo - fivhiri. Panguva iyi, yemanyorero kubva murwere kwevanhu neutachiona mosquito, uye pacharo inova mutakuri chirwere. The saibva marariya tupukanana kupinda mudumbu umhutu, unokurumidza kuibva, inoparadzirwa uye rakatangwa pasi gastric epithelium. Pano zygote inowedzerawo uye yakapatsanurwa. Panoperera ichitanga raputsika, uye ropa achaendeswa mapazi ose uye munyama. rinoungana Most mu nemate, iyo umhutu uye hwacho nedambudziko mutsva - munhu. Saka, zviri pachena kuti munhu - chete zvenguva wehondo Plasmodium nekuti kubereka anotora nzvimbo chete panguva umhutu, unova zvachose hondo.

Muvanhu, marariya kunoratidzwa mukuru tembiricha uye kunonyengedza vangadikitira. Fever rinovapo maawa anenge matanhatu nemasere, murwere ane nyota, kunzwa nefivhiri, dzava kurwadza. Nefivha ngozi mukuru-tembiricha zviratidzi - imwe mana madhigirii (a puroteni pazvirugu uye rufu kunoitika apo makumi mana navaviri mumuviri womunhu). Ichi ndicho muviri achipindura nokubudiswa zvinokachidza pamusana dzinokosha basa plasmodium uye kusunungurwa heme. Nezvokumutswa yemazuva matatu kutenderera zvina Plasmodium tembiricha uyewo skips maererano kumwedzi. Kana inodzokororwa kukundwa, muprista tembiricha iri vakaramba kugara - ichi ndicho pachikuva kupfuura nengozi. Kazhinji, muviri unotanga kubereka antibodies nokukurumidza.

Zvikuru ngozi achinaya nemarariya kuti vagari makondinendi non-African - ivo zvokuvapfuura kushivirira chirwere nokuda kwokushayiwa kurwisa mashandiro kuti Africans zvakanaka yakasimbiswa.

Kuitira kudzivisa nezvirwere marariya, kudzivisa mosquito ikaruma, regai kuva nzvimbo pedo dzanyorova, wetlands, dondo makungwa, achitora zvemaziso (mambure) uye namakemikari zvigadzirwa (mumakenduru, bhurandi), Anti-mosquito.
