Izifo zezitshalo ziya ngokuya ziba yizinsongo ekukhiqizweni kokudla, futhi eziningana zazo ziyamelana nezibulala-zinambuzane ezikhona. Ucwaningo lwaseDenmark lubonise ukuthi ngisho nasezindaweni lapho izibulala-zinambuzane zingasasetshenziswa khona, izintuthwane zingakhipha amakhemikhali avimbela ngempumelelo amagciwane ezitshalweni.
Muva nje, kutholakale ukuthi izintuthwane zase-Afrika ezinemilenze emine ziphethe izinto ezingabulala amagciwane e-MRSA. Lokhu kuyigciwane elibi kakhulu ngoba ziyamelana nama-antibiotic aziwayo futhi zingahlasela abantu. Kucatshangwa ukuthi izitshalo kanye nokukhiqizwa kokudla nakho kusongelwa yizifo zezitshalo ezingamelana nazo. Ngakho-ke, izitshalo zingazuza futhi kuzinto ezikhiqizwa yizintuthwane ukuze zizivikele.
Muva nje, ocwaningweni olusha olusanda kushicilelwa ku-“Journal of Applied Ecology”, abacwaningi abathathu base-Aarhus University babukeze izincwadi zesayensi ezikhona futhi bathola inani elimangalisayo lezindlala zezintuthwane namabhaktheriya ezintuthwane. Lezi zinhlanganisela zingabulala amagciwane abalulekile ezitshalweni. Ngakho-ke, abacwaningi basikisela ukuthi abantu bangasebenzisa izintuthwane kanye “nezikhali” zazo zokuzivikela ngamakhemikhali ukuvikela izitshalo zezolimo.
Izintuthwane zihlala ezidlekeni ezinabantu abaningi futhi ngenxa yalokho zichayeke ekudluliseleni izifo eziyingozi kakhulu. Kodwa-ke, sezisungule imithi yazo yokulwa nezifo. Izintuthwane zingakhipha izinto ezilwa namagciwane ngezindlala zazo kanye namakoloni akhula ngamagciwane.
"Izintuthwane zijwayele ukuhlala emiphakathini enabantu abaningi, ngakho-ke ama-antibiotic amaningi ahlukahlukene athuthukile ukuze azivikele wona kanye namaqembu awo. Lawa ma-compounds anomthelela omkhulu ezinhlobonhlobo zezifo ezibangelwa amagciwane ezitshalweni," kusho uJoachim Offenberg we-Institute of Biological Sciences e-Aarhus University.
Ngokwalolu cwaningo, kunezindlela okungenani ezintathu ezahlukene zokusebenzisa ama-antibiotic ezintuthwane: ukusebenzisa ngqo izintuthwane eziphilayo ekukhiqizweni kwezitshalo, ukulingisa amakhemikhali okuvikela amakhemikhali ezintuthwane, kanye nokukopisha izintuthwane ngokufaka ikhodi yezakhi zofuzo zama-antibiotic noma amabhaktheriya bese udlulisela la ma-gene ezitshalweni.
Abacwaningi babonise ngaphambilini ukuthi izintuthwane ezibazi “ezithuthela” emasimini ama-apula zinganciphisa inani lama-apula atheleleke ngezifo ezimbili ezahlukene (ukubola kwekhanda lama-apula kanye nokubola). Ngokusekelwe kulolu cwaningo olusha, baphinde baveza iqiniso lokuthi izintuthwane zingase zikwazi ukubonisa abantu indlela entsha neqhubekayo yokuvikela izitshalo esikhathini esizayo.
