Kwimveliso yokusebenza, ubushushu, ukufuma, ukungena komoya, ezi ngongoma zintathuulawulo lwefama yenkukhu. Ngokukodwa amaqondo obushushu, amaxesha onyaka ahlukeneyo, imozulu, ukugquma uyilo lwendlu yenkukhu, izixhobo zokufudumeza kwibhoyila, imowudi yokondla, ukuxinana kokutya, ubume bekheji kuya kubangela umahluko wobushushu bendlu yenkukhu.

Kwangaxeshanye, ulungelelwaniso olungafanelekanga lokungena kwindlu yeenkukhu, isantya somoya sokungena, uxinzelelo olubi alunangqiqo, impembelelo yendawo yokungena yokungena kunye nezinye izinto ziya kubangela ukwanda komahluko weqondo lobushushu kwindawo yokungena. indlu yeenkukhu. Umahluko wobushushu mkhulu kakhulu, iinkukhu ziqhelene nokubanda kunye nezifo ezibangelwa yingqele yokuphefumla kunye nezifo zokugaya ukutya, okukhokelela ekufunxeni kakubi kwe-yolk kwamantshontsho, kwangaxeshanye kuchaphazela ukusebenza kwamajoni omzimba, ukunciphisa isizukulwana se-antibody kunye nokugonywa kwe-humoral, okukhokelela ekucinezelekeni kwamajoni omzimba kwiinkukhu, okukhokelela ekunciphiseni ukuxhathisa kwizifo zeenkukhu, ukwenzeka kwezifo.

Umahluko wamaqondo obushushu ubandakanya: umahluko wobushushu bemozulu yexesha lendalo, umahluko wobushushu phakathi kwemini nobusuku, umahluko wobushushu benkukhu, umahluko wobushushu phakathi kweminyaka yobudala, umahluko wobushushu besisu sangasemva kunye nokwahlukana kobushushu, ukwandiswa komahluko wobushushu, ikheji ngaphakathi nangaphandle umahluko wobushushu, Umahluko phakathi kwangaphakathi nangaphandle, iqondo lobushushu elingaphakathi, umahluko wobushushu, umahluko wobushushu, umaleko wekheji, umahluko wobushushu ngaphambi nasemva kwendlu yenkukhu, umahluko weqondo lobushushu, umahluko wobushushu kunye nesantya somoya uziva ubushushu bomzimba, ukufuma, ukuziva ubushushu bomzimba, ukukhanya komzimba Umahluko, umzimba olambileyo uziva umahluko wobushushu, njl.
