Izifo zezityalo ziya ziba yingozi ngakumbi kwimveliso yokutya, kwaye uninzi lwazo alunazo izibulali-zinambuzane ezikhoyo. Uphononongo lwaseDenmark lubonise ukuba nakwiindawo apho izibulali-zinambuzane zingasasetyenziswa khona, iimbovane zinokukhupha izinto ezithintela ngempumelelo iintsholongwane zezityalo.
Kutshanje, kufunyaniswe ukuba iimbovane zaseAfrika ezinemilenze emine zineekhompawundi ezinokubulala iintsholongwane ze-MRSA. Le yintsholongwane embi kakhulu kuba ayixhathisi kwiintsholongwane ezaziwayo kwaye inokuhlasela abantu. Kucingelwa ukuba izityalo kunye nemveliso yokutya nazo zisengozini yezifo zezityalo ezingaxhathisi. Ke ngoko, izityalo zinokuzuza kwiikhompawundi eziveliswa ziimbovane ukuze zizikhusele.
Kutshanje, kuphando olutsha olusandula ukupapashwa kwi-"Journal of Applied Ecology", abaphandi abathathu abavela kwiYunivesithi yase-Aarhus baphonononge iincwadi zesayensi ezikhoyo baza bafumana inani elimangalisayo lee-ant glands kunye nee-ant bacteria. Ezi zinto zinokubulala iintsholongwane ezibalulekileyo kwizityalo. Ke ngoko, abaphandi bacebisa ukuba abantu banokusebenzisa iimbovane kunye "nezixhobo" zazo zokuzikhusela ngeekhemikhali ukukhusela izityalo zezolimo.
Iimbovane zihlala kwiindawo ezixineneyo kwaye ngenxa yoko zisengozini yokudluliselwa kwezifo ezinobungozi obukhulu. Nangona kunjalo, ziye zavelisa amayeza azo okulwa nezifo. Iimbovane zinokukhupha izinto ezibulala iintsholongwane ngamadlala azo kunye neekoloni zebhaktheriya ezikhulayo.
"Iimbovane ziqhele ukuhlala kwiindawo ezixineneyo, ngoko ke amayeza amaninzi okubulala iintsholongwane aphuhlisiwe ukuze azikhusele wona kunye namaqela azo. La mayeza anefuthe elikhulu kwiintlobo ngeentlobo zezifo ezibangelwa zizityalo," utshilo uJoachim Offenberg we-Institute of Biological Sciences kwiYunivesithi yase-Aarhus.
Ngokwale phando, kukho ubuncinane iindlela ezintathu ezahlukeneyo zokusebenzisa amayeza okubulala iintsholongwane eentshulube: ukusebenzisa ngokuthe ngqo iimbovane eziphilayo kwimveliso yezityalo, ukulinganisa iikhompawundi zokukhusela iikhemikhali zeentshulube, kunye nokukopa iiimbovane ngokufaka i-antibiotic okanye ii-bacterial genes kunye nokudlulisela ezi gene kwizityalo.
Abaphandi babonakalise ngaphambili ukuba iimbovane ezisebenzisa umatshini “ezifudukela” kwiindawo zokutyala ama-apile zinokunciphisa inani lama-apile asuleleke zizifo ezibini ezahlukeneyo (i-apple head blight kunye nokubola). Ngokusekelwe kolu phando lutsha, baqhubele phambili babonisa ukuba iimbovane zinokukwazi ukubonisa abantu indlela entsha nezinzileyo yokukhusela izityalo kwixesha elizayo.
