Host esiPhakathi - yinto ephilayo apho ubomi amakhalane kunye iintlobo

Umjikelo wobomi lweentshulube ezininzi ngokumangalisayo ezintsonkothileyo. Ukuya kuzo zonke izigaba zophuhliso, kufuneka ixesha ngakumbi ukutshintsha umkhosi. Enye yezi iya kuba iinginginya eziphambili. Xa umzimba wakhe ezimfimfitha igazi liya kuba nako ukuvelisa ngokwesondo okanye asexually. Kodwa siza kuthetha umkhosi eliphakathi.

Yintoni okanye ngubani na umkhosi Intermediate?

host esiPhakathi - esi sinambuzane, isilwanyana okanye umntu, umzimba leyo inika ithuba ekutyeni nasemakhalaneni abahlala kweli nqanaba mibungu. Ngaphakathi umkhosi eliphakathi kunokuba ukuzala maqanda. Umzekelo, umzimba womntu inika indawo yokuhlala yethutyana ukuba seengcongconi amaphelo, tapeworm kunye nezinye izinambuzane.

Noko ke, asingabo bonke eziphilayo apho amaphelo atyelelwa kwizigaba ezahlukeneyo zophuhliso, kucingwa ukuba impi eliphakathi. Ngoko wabiza isilwanyana kuphela kugqitha umzimba apho - imfuno yenguqu kumjikelo olandelayo zophuhliso amakhalane.

wenza njani parasite kwi nginginya esiphakathi?

Ukuziphatha kwe imibungu kwi esiphakathi yokuthintela zohlulwa ngokwendidi 3:

1. Umzimba eliphakathi ilungiselela ukudlulisa ngumbungu emkhosini esichazayo. Kulo mzekelo, ebalulekileyo kuphuhliso yayo nikholwe. Umzekelo okuphawuleka trypanosomes ephuhlisa e ezanyisayo, xa umthamo iimpukane kuwa phezu nkawu labo ligazi usisisulu episamtigodnuyu ukubumba amathumbu izinambuzane kwaye sisasazwa buluma nezinye ezanyisayo.
2. Uhlobo lwesibini lokuziphatha iqatshelwe umzimba mkhosi esiphakathi, apho irhorho kutshintsha, kodwa hayi nande. Ngamashishini ivela emzimbeni, inani lweentshulube ubanjwe ngazo ukhulise. Olu umjikelezo wophuhliso ineendidi ezininzi ziintshulube kunye tapeworm.
3. A Uhlobo lwesithathu lokuziphatha kunokwenzeka ukuba umkhosi eliphakathi - umzimba apho wenziwa kuphela uphuhliso, kodwa ukuzala maqanda. Kulo mzekelo, umzimba esiphakathi kukutshisa ukufumana amaphelo enye, kwaye imveliso iya kuba ezininzi amawaka, ekulungele ukungena iinginginya esichazayo.

onke nesiGaba esiPhakathi ngokweProjekthi izinambuzane

Cinga ngendlela ethile sisidleleli, umnini ephambili yaloo mntu, impi eliphakathi - iinkomo (ithokazi, inkunzi). Sithetha malunga yenkomo Chain bengaxhobanga.

Emzimbeni womntu elikhulu tapeworm uyalinandipha yenkomo kakubi ngayo. Tsesterki kwangena nyama kwaye uqale uphuhliso esebenzayo. Isiphumo sale uphuhliso yehagu omkhulu uhlala emathunjini abantu. ubude worm inako ukufikelela mitha 12-14!

Emzimbeni, umkhosi amaphelo engundoqo ungaphila kumntwana ominyaka imashumi, ngelo xesha uvelisa ezigidi amaqanda, nto leyo iya kukhululwa emathunjini kunye isitulo, abanye babo baqhubeke uphuhliso lwabo emkhosini esiphakathi. Njengoko kukhankanyiwe, kulo mzekelo host eliphakathi - yinto inkomo okanye inkomo.

Ethunjini abameli bempahla amaqanda Imibungu kuvela (hexacanth) zixhotyiswe namagwegwe ezikhethekileyo. Bona imngene inyama wamathumbu nditshize wonke umzimba. Xa imisipha iinkomo imibungu kuya inyathelo elilandelayo, zakha eFinland, nto leyo eya kulindeleka ukuba angene umzimba omkhulu yenethiwekhi.

flukes isibindi

Cinga uhlobo olunye lweentshulube kunye kumjikelo nokwanda entsonkothileyo apho kukho wemikhosi eziliqela intermediate. Eli qela ekuthiwa flukes zesibindi. Ezi ziquka isibindi kunye cat Iphiko, ingxilimbela, lanceolate kunye liphiko Chinese.

Inginginya lokuqala intermediate kwesibindi Iphiko - a lembaza. Umzimba wakhe ezidla usisisulu zigaba ezininzi yokuzalwa ngokutsha: miracidia, sporocysts rediae. Kwaba kuphela isizukulwana yesithathu kombungu - flukes siphuma emzimbeni silwanyana ekhangela yomkhosi elandelayo esiphakathi.

Le yesibini intermediate host zesibindi Iphiko (flukes) - iintlanzi. Amaxesha amaninzi basonta kusapho zeCARP. Xa ukuwisa yityuwa iteknoloji okanye unyango ubushushu ngokwaneleyo esikule of flukes zeentlanzi eyele host ephilayo lokugqibela, ukuyohlala esibindini okanye inyongo imibhobho. Ukuze umntu eyingozi Chinese Iphiko kunye cat liphiko.

Lancet ngengozi

Olunye uhlobo - lanceolate Iphiko, le udaka umzimba yokuqala intermediate tapeworm alandelayo host esiphakathi - ant, kwaye umkhosi kokuphilayo sokugqibela - esidla.

Kumjikelo yophuhliso phindwa amaqanda eziphambili host kufuneka bangene kokusingqongileyo, elileli, ichibi. Apha "kuginya" host eliphakathi. Oku kwenzeka ukusuka kwisizukulwana ukuya kwisizukulwana, ekubeni indoda ayikho esweni ngokwaneleyo nokucoceka amanzi kwaye ivumela ukuba kuchithwe amanzi amdaka ngaphandle ukucoca efanelekileyo.

kwemvelo, ebangela gazi ukutshintsha onke ngokubanzi,, kunciphisa umthwalo ephilayo, kunciphisa ukhuphiswano intraspecific khipha ukuxhomekeka imeko enye. indlela Complex kwemvelo busisigxina kwinqanaba yemfuza, irhorho, kwaye ivumela ukuba ndikhuphe inzuzo ubuninzi kwisigaba ngasinye uphuhliso.
