Ofufuza ku yunivesite ya South Florida agwiritsa ntchito luntha lochita kupanga kupangamisampha ya udzudzupoyembekeza kuwagwiritsa ntchito kunja kuti apewe kufalikira kwa malungo.
TAMPA - Msampha watsopano wanzeru pogwiritsa ntchito luntha lochita kupanga udzagwiritsidwa ntchito potsata udzudzu womwe umafalitsa malungo ku Africa. Ndi ubongo wa ofufuza awiri ochokera ku yunivesite ya South Florida.
"Ndikutanthauza, udzudzu ndi nyama zakufa kwambiri padziko lapansi." Izi kwenikweni ndi singano za hypodermic zomwe zimafalitsa matenda, "anatero Ryan Carney, pulofesa wothandizira wa sayansi ya digito mu Dipatimenti ya Integrative Biology ku yunivesite ya South Florida.
Udzudzu wofalitsa malungo, Anopheles Stephensi, ndiwo cholinga cha Carney ndi Sriram Chellappan, mapulofesa a sayansi ya makompyuta ndi uinjiniya pa yunivesite ya South Florida. Iwo akuyembekeza kulimbana ndi malungo kunja ndikugwira ntchito limodzi kuti apange misampha yanzeru, yochita kupanga kuti azitsatira udzudzu. Misampha iyi ikukonzekera kugwiritsidwa ntchito ku Africa.
Mmene msampha wanzeru umagwirira ntchito: Choyamba, udzudzu umawulukira m’dzenjelo ndiyeno n’kutera pampando womata umene umawakopa. Kamera mkati mwake imatenga chithunzi cha udzudzu ndikuyika chithunzicho pamtambo. Ofufuzawo adzayendetsa njira zingapo zophunzirira makina kuti amvetsetse mtundu wa udzudzu kapena mitundu yake yeniyeni. Mwanjira imeneyi, asayansi azitha kudziwa komwe udzudzu womwe uli ndi malungo umapita.
"Izi ndi nthawi yomweyo, ndipo udzudzu wa malungo ukapezeka, chidziwitsocho chikhoza kuperekedwa kwa akuluakulu a zaumoyo pafupifupi nthawi yeniyeni," adatero Chelapan. "Udzudzuwu uli ndi madera ena kumene umakonda kuswana. Ngati ungathe kuwononga malo oswanawo, nthaka.
"Itha kukhala ndi zoyaka moto. Itha kuletsa kufalikira kwa ma vectors ndikupulumutsa miyoyo," adatero Chelapan.
Malungo amakhudza anthu mamiliyoni ambiri chaka chilichonse, ndipo yunivesite ya South Florida ikugwira ntchito ndi labotale ku Madagascar kuti itchere misampha.
Carney anati: “Chaka chilichonse, anthu oposa 600,000 amamwalira. "Chotero malungo ndi vuto lalikulu komanso lomwe likupitilirabe padziko lonse lapansi."
Ntchitoyi idathandizidwa ndi thandizo la $ 3.6 miliyoni lochokera ku National Institute of Allergy and Infectious Diseases of the National Institutes of Health. Kukhazikitsidwa kwa ntchitoyi ku Africa kudzathandizanso kuzindikira udzudzu wofalitsa malungo m’chigawo china chilichonse.
"Ndikuganiza kuti milandu isanu ndi iwiri ku Sarasota (Chigawo) ikuwonetsadi vuto la malungo. Sipanakhalepo kufalitsa malungo m'deralo ku United States m'zaka 20 zapitazi," anatero Carney. "Tilibe Anopheles Stephensi panobe.
Smart Trap igwira ntchito limodzi ndi tsamba lomwe lakhazikitsidwa kale padziko lonse lapansi. Izi zimathandiza nzika kutenga zithunzi za udzudzu ndi kuzikweza monga njira ina younikira. Carney adati akukonzekera kutumiza misampha ku Africa kumapeto kwa chaka chino.
"Ndondomeko yanga ndikupita ku Madagascar ndipo mwina Mauritius isanafike nyengo yamvula kumapeto kwa chaka, ndiyeno pakapita nthawi tidzatumiza ndi kubweretsanso zina mwa zipangizozi kuti tiziyang'anira madera amenewo," adatero Carney.
