I-Necatosis isifo sesifo esivela kwiqela le-ankylostomiasis, eliqhelekileyo kumazwe anesimo sezulu esitshatyalaliswayo. Izifo ze-Necatotropic zincinci ezincinane ezijikelezayo i-Necator americanus (i-americanus nekator), ephazamisa intonda encinci yabantu, kunye nezinye izilwanyana. I-Larvae ye-nekatorov ithuthuka emhlabathini phantsi kweemeko zokuphakama kwamanzi kunye nokushisa 14 -40 ° C, apho bahamba khona ngeendlela ezihlukeneyo.
Izindlela zokusuleleka nge-carorisis
Ukuhlasela kungenzeka ngeendlela ezimbini:
- Uqha ga mshelwano (inqamana, i-percutaneous) indlela yokusuleleka - ukungena kweemvumba ze-nekatorov ngokusebenzisa izibonda zesikhumba edibeneyo nomhlaba (ngokuqhelekileyo ngesikhumba semilenze). Kanye emzimbeni, izibungu ze-helminths zingene emifuleni yegazi kwaye zidluliselwa kwimipopeni ngegazi. Ngaphezulu, nge-phlegm, xa i-larva iqala ukukhwehlela, ingena emlonyeni womlomo, iginye kwaye iphele kwisisu, ize ingene emathunjini.
- Indlela ye-Fecal-oral yokusuleleka kukungena kweeqanda ze-helminth, zixutywe emhlabathini ngamanqatha, emzimbeni womntu ngokusebenzisa umlomo womlomo kunye nokusetyenziswa kwemifuno engcolileyo, izithelo kunye namanzi angcolileyo. Kule meko, akukho ukufuduka kwezibungu emzimbeni, bafikelela kwi-duodenum, apho baqala ukuphuhliswa kwinqanaba elivuthiweyo.
Iimpawu ze nikatorosis
Ixesha lokuxubusha kwezifo lingahlala kwiintsuku ezingama-40 ukuya kwiinyanga ezi-2. Iziganeko ze-Dyspeptic, iimpawu ezikhuselekileyo kunye nokuphuhliswa kwe- anemia ziyimpawu ezingekho kwi-katorosis. Kwi-penetaneous penetration ezinjalo ziboniswa:
- kubomvu kwesikhumba;
- ukuvutha komlilo, ukubetha;
- iziphulo ezahlukahlukeneyo (iphepha, ipustular, erythematous, njl).
Ngethuba lokufuduka kweemvumba ezinobungqina ngokuphefumula, iziganeko ze-catarrhal zivame ukubonwa, i-dyspnea, i-wheyzing, ne-bronchitis, i-pleurisy, kunye ne-pneumonia nazo zinokwenzeka.
Ukuhlaselwa kwendlela yokuxhamla isisu kuhamba kunye nezi zimpawu:
- ukuguquka ;
- ukungabikho okanye ukwanda kwesidlo;
- isicefe
- ukuhlanza;
- intlungu esiswini;
- isifo sohudo.
Ukudibanisa kwiindonga zamathumbu, i-nekatory ibangela ukubonakala kwezilonda kunye nezidumbu. Oku kukhokelela ekuphuhliseni ukuphuma kwegazi, leyo yimbangela yokunqongophala kwe-anemia yensimbi. Ubomi beepasisiti emathunjini malunga nonyaka, kodwa ezinye i-helminths zihlala iminyaka emininzi.
Unyango lwe-non-katorosis, kunye nezinye iintlobo ze-ankylostomiasis, ascariasis, i-toxocarosis, njl., Zenziwa ngoncedo lwabadlali be-anthelmintic ye-action range.
