IYunivesithi yaseCalifornia, izazinzulu zaseBerkeley zicela uncedo kuluntu ekulandeleni isifo esibulala imithi ye-oki.
Kule minyaka mibini idlulileyo, izazinzulu bezithembele kubahlali ukuba baqokelele iisampulu zemithi baze bayithumele kwiLebhu yeForest Pathology and Mycology yale yunivesithi. Basebenzise ulwazi ukwenza imephu yokucwangcisa ukusasazeka kokufa kwe-oki ngequbuliso.
Ipathogen engaqondakaliyo yafunyanwa okokuqala eMill Valley ngo-1995 kwaye sele ibulele amashumi amawaka emithi kumantla eCalifornia nakumazantsi eOregon. Izazinzulu ziqikelela ukuba esi sifo, sisasazwa zizityalo namanzi, sinokubulala ama-90 ekhulwini emi-oki ephilayo yaseKhalifoniya kunye nemi-oki emnyama kwiminyaka engama-25.
Iprojekthi yokwenza imephu, exhaswa ngemali yiNkonzo yeHlathi yase-US, yinzame yokuqala esekwe kuluntu ukulwa nokufa ngequbuliso kwe-oki. Ibinabathathi-nxaxheba abamalunga nama-240 abaqokelele iisampulu ezingaphezulu kwe-1,000 XNUMX kulo nyaka uphelileyo, utshilo uMatteo Garbelotto, ugqirha wezifo zamahlathi e-UC Berkeley kunye nengcali ephambili yelizwe ngokufa ngequbuliso kwe-oki.
“Le yinxalenye yesisombululo,” utshilo uGarbelotto kwiSan Francisco Chronicle. "Ukuba siyafundisa kwaye sibandakanya abanini bepropathi ngabanye, singenza umahluko omkhulu kakhulu."
Nje ukuba kuchongiwe indawo ezele luhlaselo, abaninimzi banokususa imithi yemithi, nto leyo enokunyusa izinga lokusinda kwe-oki ngokuphindwe kalishumi. Abahlali bakwabongozwa ukuba bangenzi imisebenzi emikhulu enokuphazamisa umhlaba nemithi ngexesha lemvula kuba inganceda ekusasazeni esi sifo.
“Uluntu ngalunye olufunde ukuba lufe ngequbuliso lwe-oki kwindawo yalo kufuneka luthi, 'Heyi kungcono ndenze into,' kuba xa ubona ukuba imithi iyafa, sele kusemva kwexesha,” utshilo uGarbelotto.
