Necatosis chirwere chinorwara kubva kune boka re ankylostomiasis, iro rinowanzoonekwa kune dzimwe nyika dzine mamiriro okunze uye anogara pasi. Necatotropic pathogens zviduku zvakapoteredza nyuchi Necator americanus (an americanus nekator), iyo inoparadzanisa mumutsipa muduku wevanhu, pamwe nemamwe mhuka. Larvae ye nekatorov inobudirira muvhu iri pasi pemamiriro ekudzivirira kwepamusoro uye kutonhora 14 - 40 ° C, iyo inofamba nenzira dzakasiyana.
Nzira dzehutachiona nevasina carorisis
Kukoka kunogona kuitika nenzira mbiri:
- Kukurukurirana (nzira yakasiyana-siyana, yakasiyana-siyana) nzira yehutachiona - kupindira kwemapuranga e-nekatorov kuburikidza nepora dzeganda rinosangana nevhu (kazhinji kuburikidza neganda remakumbo). Imwe muviri, masuruva e helminths anopinda mumidziyo yeropa uye anotumirwa kumapapu neropa. Uyezve, nemapurogm, apo maperembudzi anotanga kukanganisa, vanopinda mumuromo, vanomedza uye vanoguma mudumbu, uye vozopinda mumukumbo.
- Nzira inofanirwa nemuromo inokonzerwa nehutachiona ndiyo inopinda mazai e helminth, yakanyongedzerwa muvhu nevhu, ichipinda mumuviri wemunhu kuburikidza nemumuromo wemuromo uye kushandiswa kwemiriwo isina kushambidzwa, michero, uye mvura yakasvibiswa. Muchiitiko ichi, hapana kubuda kwemaruva kune muviri, vanosvika ku duodenum, kwavanotanga kukurudzira kusvika pachigarire chepabonde.
Zviratidzo zveNikatorosis
Nguva yekudzivirira iyo chirwere inogona kupera kubva mumazuva makumi mana kusvika kumwedzi miviri. Dyspeptic phenomena, allergenic zviratidzo uye kukura kwehupenyu hwekushaya ropa kune unhu hwekusava katorosis. Pachinhu chinopfurikidza kupindira zviratidzo izvi zvinowanikwa:
- kubwinya kweganda;
- kutsva kwekunzwa, kuchenesa;
- kuputika kwakasiyana-siyana (papular, pustular, erythematous, nezvimwewo).
Munguva yekufamba kwehonye mhondi kuburikidza nehutano hwemapfupa, catarrhal phenomena inowanzoonekwa, dyspnea, wheezing, uye bronchitis, pleurisy, uye pneumonia zvinogonawo.
Kurwiswa kwepamuviri wepamuviri kunofambidzana nezviratidzo zvakadaro:
- kuchema ;
- kusavapo kana kukura kwechido;
- nausea;
- kurutsa;
- kurwadziwa mumimba;
- chirwere.
Kusangana kumadziro emukumbo, kusava nehanya kunokonzera kuonekwa kwezvironda uye kukanganisa. Izvi zvinotungamirira pakuvandudzwa kwekubuda ropa, iyo ndiyo iyo inokonzerwa nekushaiwa kwesimbi kushaya anemia. Upenyu hwezvipembenene mumatumbo hunenge gore, asi mamwe helminths anogona kurarama kwemakore anoverengeka.
Kurapa kwekusava katorosis, pamwe chete nemamwe marudzi e ankylostomiasis, ascariasis, toxocarosis, nezvimwewo, inoitwa nekubatsirwa kwevanhu vasingazivikanwi vanoita mabasa akawanda.
