I-Beauveria bassianaisikhunta esithakazelisayo nesiguquguqukayo esivame ukutholakala emhlabathini kodwa futhi singahlukaniswa nezinhlobonhlobo zezinambuzane.Le entomopathogen iye yacwaningwa kabanzi ukuze isetshenziswe ekulawuleni izinambuzane, njengoba iyisitha semvelo sezinambuzane eziningi ezilimaza izitshalo ngisho nabantu imbala.Kodwa kungabaI-Beauveria bassianaukuthelela abantu?Ake sikuhlole lokhu ngokuqhubekayo.
I-Beauveria bassianayaziwa ngokuyinhloko ngokusebenza kwayo ekulawuleni izinhlobonhlobo zezinambuzane.Ithelela izinambuzane ngokunamathela ku-exoskeleton yazo futhi ingene ku-cuticle, kamuva ihlasele umzimba wezinambuzane futhi ibangele ukufa.Lokhu kwenzaI-Beauveria bassianaenye indlela engahambisani nemvelo kunezibulala-zinambuzane zamakhemikhali, njengoba iqondise ngokuqondile izinambuzane ngaphandle kokulimaza ezinye izinto eziphilayo noma indawo ezungezile.
Nokho, uma kuziwa emandleni okuthelela abantu, indaba ihluke kakhulu.NakubaI-Beauveria bassianaisicutshungulwe kabanzi futhi yasetshenziselwa ukulawula izinambuzane, azikho izigameko ezibikiwe zokutheleleka kwabantu okubangelwa yilesi sikhunta.Lokhu kungase kube ngenxaI-Beauveria bassianaiye yavela ukuze iqonde ngokuqondile izinambuzane, futhi amandla ayo okuthelela abantu alinganiselwe kakhulu.
Ucwaningo lwaselabhorethri luye lwathola ukuthiI-Beauveria bassianaingamila esikhumbeni somuntu kodwa ayikwazi ukungena ku-stratum corneum, ungqimba olungaphandle lwesikhumba.Lesi singqimba sisebenza njengesithiyo futhi sinikeza isivikelo kuma-microorganisms ahlukahlukene.Ngakho-ke,I-Beauveria bassianamancane kakhulu amathuba okuba kubangele ukutheleleka kwesikhumba somuntu esingaguquki.
Ukwengeza, ucwaningo luye lwabonisa lokhoI-Beauveria bassianaayibeki engcupheni enkulu empilweni yomuntu ngokuhogela umoya.I-Beauveria bassianaama-spores makhulu futhi asindayo, okwenza ukuthi abe mancane amathuba okuba ahambe emoyeni futhi afinyelele ohlelweni lokuphefumula.Ngisho noma efika emaphashini, asheshe asulwe yizinqubo zokuzivikela ezingokwemvelo zomzimba, njengokukhwehlela kanye nokususwa kwe-mucociliary.
Kubalulekile ukuqaphela ukuthi ngenkathiI-Beauveria bassianakubhekwa njengokuphephile kubantu, abantu abanamasosha omzimba asengozini, njengalabo abane-HIV/AIDS noma labo abathola ukwelashwa ngamakhemikhali, bangase babe sengozini yokuthola izifo ezihlukahlukene zesikhunta, okuhlanganisaI-Beauveria bassiana) ukutheleleka.Ngakho-ke, ngaso sonke isikhathi kunconywa ukuthi uqaphe futhi ufune iseluleko sezokwelapha uma kukhona ukukhathazeka mayelana nokuchayeka kunoma iyiphi isikhunta, ikakhulukazi kubantu abangenawo amandla omzimba.
Ngokufigqiwe,I-Beauveria bassianaiyi-pathogen yezinambuzane ephumelela kakhulu esetshenziswa kakhulu ekulawuleni izinambuzane.Nakuba ikwazi ukumila esikhumbeni somuntu, ayikwazi ukubangela izifo ngenxa yesithiyo sokuzivikela esingokwemvelo somzimba wethu.Azikho izehlakalo ezibikiwe zeI-Beauveria bassianaukutheleleka kubantu, futhi ingozi empilweni yomuntu ngokuvamile ibhekwa njengento engenamsebenzi.Kodwa-ke, uma kukhona okukhathazayo, ikakhulukazi abantu abanamasosha omzimba asengozini, kufanele kuqashelwe futhi kufunwe iseluleko sochwepheshe.
Sekukonke, ucwaningo lubonisa ukuthi abantu akudingeki bakhathazeke ngokungenwa yigciwaneI-Beauveria bassiana.Kunalokho, lesi sikhunta esimangalisayo siyaqhubeka sidlala indima ebalulekile ekulawuleni izinambuzane, ukugcina izitshalo ziphilile futhi zivikela imvelo.
