Umjikelezo Development nokuphila Ascaris

Kuyini ascariasis? Lesi sifo helminths ujabule Ascaris, ivaleleke abantu by umzila ngomlomo. Kule isifo sihlasela abantu emhlabeni wonke, ngisho ezindaweni eziwugwadule futhi ezindaweni lapho eyiqhwa. Ukuze uqonde izimbangela yalesi sifo, udinga ukuthola indlela ukuthuthukisa worm.

imithombo okutheleleka

Land ingcoliswe imikhiqizo womuntu imfucuza futhi ungumthombo oyinhloko isifo ascariasis. Ngaphambi siyathola ukuthi ejenti causative, cabanga umjikelezo wokuphila ka Ascaris. Abakwazi itheleleke ngezandla ezingcolile, izithelo, amajikijolo, imifino, okokuqala ke siphathelene zasemazweni. Ngaphezu kwalokho, ascaris isibungu ibekezelelwe izinambuzane ezehlukene, fly ethile nge itholethe, indlini encane emgwaqweni. umuntu ngokuqondile abangenwe kusukela indoda cishe kungenakwenzeka. Kusekhona ezinye zezindlela ukudluliswa Ascaris, nazi ayinhloko:

1. Amanzi ezivela emithonjeni oxhumana nabo enobuthi kusuka indle. Kubalulekile ukukhumbula ukuthi amanzi emhlabathini - lokhu akusona isiqinisekiso of msulwa.
2. Izingane angaba ngokwemvelo, ngenxa Ascaris izibungu kungaba yonke indawo.
3. Ezimweni gqwa - ukudluliswa ukutheleleka nge placenta.
4. Autoinfection. Kukhona amacala lapho amaqanda Ascaris abavuthiwe ngqo emzimbeni womuntu, futhi ngaleyo ndlela kuyenzeka futhi ukusilaphazeka.

Kuyini Ascaris?

Ngaphambi kokuba sihlole umjikelezo yentuthuko izikelemu womuntu, kumele inikezwe, kubukeka sengathi lesi silwanyana worm. izimpethu Phila Unomzimba ngesimo umbala lokuphotha Pinkish. Worm isisulu olumhlophe-yellow. Ubude umzimba Ascaris insikazi ingase ibe kusuka 25 kuya 40 cm, ububanzi - 4 kuya 6 mm. Ubude wesilisa - 15-25 cm, nobubanzi - 4.2 mm.

Ngokocansi izikelemu ovuthiwe ngokuvamile abahlala emathunjini amancane wabantu sondle ngalokho elikuqukethe. Impilo ka-amagciwane imayelana ngonyaka. Ngo ezibalulekile idatha lakwazi ukunakekela amaphuphu alo ubuthi ubuthi ehlukahlukene nomzimba. Exchange imikhiqizo nokubuna bona izifo kubantu, ezifana ukuvuvukala hepatic noma ukuqubuka esikhumbeni. Abadala ascarids kakhulu sensitive-mpilo yilezi: it enza them abulawe, ngakho lapho bangena imvelo, wabulala masinyane.

Izimpawu ascaris

Abesilisa nabesifazane ababonakali ngezikhundla komunye nomunye hhayi kuphela ubukhulu kodwa futhi ukuma umsila. Kwabesifazane, umsila Isigaxa iphutha, kanti amaduna - izimisele simise hook. Ubulili izitho aqukethe ezidala:

1. Ngo Kwabesifazane, amaqanda yomzimba imibhangqwana ukuba athola amaqanda, 2 izindlovukazi ukuthi bangene isitho sobulili yangaphandle - sangasese.
2. Ngo esilisa gonads - the testes neziteshi vas semyaizvergayuschih 2 spicules kusuka 0.15 kuya 0.2 cm ubude.

ascaris isimiso sokugaya ukudla bungene siqukethe le ngalo ingaphakathi ngomlomo, emphinjeni eside ukuba simise cylindrical nge tube emathunjini ku ekupheleni ingquza. Ukuguquguquka kwempilo le izikelemu womuntu ihlala isikhathi esingangonyaka. Lezi yizilwanyana eziwuhlupho kukhona wenzalo ezahlukene. NgoLwesine kutholakale isidumbu sendoda insikazi ngesikhathi esifanayo lingafika ku-27 million. Amaqanda lamadigri ukuvuthwa obuhlukahlukene. Ubusuku ngabunye Ascaris ongabeka amayunithi 240.000.

Uyini umahluko kusuka amaqanda avundiswa ka Ascaris kalanzalo?

amaqanda izikelemu ukuthi avundiswa, kukhona kobujamo obusaqanda noma eyindilinga. Ubukhulu kungenzeka kusuka 50-70 kuya 40-40 microns. Iqanda siqukethe igobolondo multilayer zokuzivikela. Ngaphandle kuyinto amaprotheni ulwelwesi, kuba esingemnandi futhi siyolungisa kuze iqanda kuyinto esizalweni wentombazane. Khona-ke umjikelezo ukuthuthukiswa izikelemu uyaqhubeka. Ngemva ukuxhumana amaqanda amagciwane e amathumbu, igobolondo iba nsundu noma emnyama ophuzi kanye ilahlekelwa ngale. Kodwa ingxenye engaphakathi uhlala bushelelezi futhi esobala, ivikela i-fetus kusukela eyingozi chemical. Ngaphakathi iqanda kuyinto yeseli esiqubukile ngesikhathi division ezithile, nge shape eyindilinga futhi nsuku luyimbudumbudu. Ngezinye izikhathi amaqanda ukuxilonga kanzima ngokwanele beswela udonga lwangaphandle.

amaqanda Unfertilized neziphandla umjikelezo ethile yentuthuko izikelemu womuntu, falling umdwebo zomzimba womuntu akuhlukile avundiswa. Ukwehluka kwi-ubukhulu ezahlukene. udonga lwangaphandle - amaprotheni has a ukuthungwa anolaka nge okungajwayelekile kushintshana amazinyo. Ngaphakathi iqanda kuyinto iseli isikhuphasha. Lapho amaqanda unfertilized beswela udonga lwangaphandle, kunzima kakhulu ukunquma ukuthi kuyini, futhi kungaba lula ukudida ngayo iseli isitshalo.

umjikelezo ukuthuthukiswa izikelemu

Amaqanda abelwe ngesitulo zomzimba womuntu futhi ingagcinwa iminyaka engaba ngu-10 ngaphansi kwezimo ezimvunayo. Sinenkosi ukumelana uhlanzekile amakhemikhali amanzi, kodwa elicwengekileyo futhi bafe uma abilayo. Ukuze ngibone umjikelezo wokuphila kwe Ascaris baqhubeka isidingo Iqanda ongene isigaba esithile, sesiye koda - esithathelwanayo ukuba abantu. Kufanele baqale ukuthuthukisa isibungu. Lokho kwenza ukwakheka mpilo, alikho esiswini. Ngakho-ke, lapho amaqanda adedelwa emvelweni, eqala ukukhula ngokushesha, ikakhulukazi uma izimo mahle. At lokushisa amaqanda mayelana 25 degrees ovuthiwe ngaphakathi 2 amaviki, ngaphandle kwalokho inqubo ingathatha izinyanga eziningana. Amaqanda abafa phakathi nesomiso kanye, isibonelo, i-isihlabathi esomile. isihlabathi Wet - imvelo elihle kunawo kuya umjikelezo wokuphila kwe-izikelemu womuntu waqhubeka impumelelo. Amaqanda zinhle ukubekezelela okushisa aphansi, kabasi yesithwathwa esabe.

Indlela izikelemu phambili

Iqanda ukuvuthwa iqukethe kwakhiwa isibungu, okuyinto ukubukwa worm curled. umjikelezo Ascaris ukuphila kuqala, kokushiya amaqanda esiswini. Kwenza nzima umzila yokufuduka izibungu ukuvuthwa abantu abazokwazi zibekela iqanda. Ngezansi kwethulwa lonke umjikelezo wokuphila kwe izikelemu, inqubo uhlelo simiswe ngalendlela lelandzelako:

1. Lezi ziphungumangathi zasondela zingene mucosa emathunjini, bese - ku-capillary.
2. Ngokusho umthambo omkhulu oholela kusukela amathumbu ukuze kwesibindi, faka isibindi.
3. I ephansi vein ngegazi - ohlangothini yangakwesokudla senhliziyo.
4. Ngokwe Umthambo yamaphaphu - emaphashini.
5. Ngaphezu kwalokho, ngokusebenzisa bronchi kanye kuqhoqhoqho - e pharynx futhi ngalo ingaphakathi ngomlomo. Lapha singagwinyi izikelemu kanye futhi ithunyelwa namathumbu.

Kuyinto lapho izibungu ukungena okwesibili emathunjini, benza izikelemu omdala.

Ubude besikhathi kufuduka kwesikhathi

Kusukela izibungu ukwakha abantu abavuthiwe kumelwe kudlule isikhathi esithile. Ngalesi sikhathi sidlule indlela kufuduka njengoba kuchaziwe ngenhla. Uthatha mayelana 2 amaviki - ngalesi sikhathi esigabeni elalikudle lapho liseyisibungu. Isikhathi kufuduka - it is a nokuvuthwa imfuneko. Ukuguquguquka kwempilo Ascaris 2.5 izinyanga uyaqhubeka ukuthi avele indle amaqanda, kodwa kwezinye izimo zingase avele ngaphambili kakhulu - emasontweni 3.

Migration isikhathi akudingeki ukuqedelwa emathunjini, izibungu kungaba axazulule futhi kamuva afele isibindi. Lapho ibekwe emlonyeni, bangakwazi nje ngamathe, ikakhulukazi lapho kukhona isikhwehlela ezinkulu. Ngezinye izikhathi ascarids atholakala ventricles kwenhliziyo, kuqhoqhoqho namaphaphu.

ezilwaneni

Izikelemu kungaholela ngendlela yisinanakazana zokuphila cishe zonke izilwane .. Amahhashi, izingulube, nezimbongolo, amathole, amakati, izinja, izinkukhu, goose, njll ngu umndeni esikhulu kakhulu izibungu esikhulu kakhulu zihlanganisa ihhashi Ascaris, umjikelezo ukuthuthukiswa ozobakhona mayelana 2 izinyanga. Ubude amagciwane -. Mayelana 40 cm ngalinye kwezilwane parasitize kuphela uhlobo oluthile worm. Ngokwesibonelo, ingulube kanye ascarids womuntu zifana kakhulu. Nokho, igciwane womuntu wezingulube amagciwane kuyinto cishe engenakwenzeka, futhi okuphambene nalokho.

Ingozi main wukuthi izibungu zibulale omzimba omuntu. Basakaza utholakala cishe kuwo wonke kwezitho nezicubu zomzimba, okubangela ukuvuvukala bokuba khona kwakhe futhi zonke izinhlobo ukuxakeka. Ngakho-ke kubaluleke kakhulu ascariasis zokuvimbela. Endabeni ukutheleleka kufanele ngokushesha uthintane onguchwepheshe. Musa self-medicate!
