Snails ayaa ka dhaqso badan inta la malayn karo, iyagoo si fudud u daboolaya mitir saacaddii. Taasi waa waxa cilmi-baarayaasha Jaamacadda Exeter ay heleen markii ay la socdeen 450 snails beerta iyaga oo isticmaalaya LEDs iyo rinjiga UV. Sidaa darteed, mollusks-yadu waxay sidoo kale jecel yihiin inay isticmaalaan nooc ka mid ah qulqulka qulqulka slime. Xaqiiqda ah in shilku si degdeg ah u dhaqaaqo waxay leedahay dhinaceeda: Gooryaanka sambabada Angiostrongylus vasorum, a dulin nafta halis gelisa ee eyda, la safra. In Great Britain, mahad sanado qani ku ah snails, waxay mar hore ka soo fidday gurigeeda awoowgeed ee koonfurta ilaa Scotland.
Snails on raad
Kooxda uu hogaaminayo ecologist Dave Hodgeson ayaa markii ugu horeysay si sax ah u diiwaangeliyay dhaqdhaqaaqa habeenkii ee snails iyagoo isticmaalaya nalalka LED ee ku xiran dhabarka xayawaanka iyo duubista waqtiyada. Waxay kaloo isticmaaleen midabada UV si ay uga dhigaan raadadka xamaaratada mid muuqda. "Natiijooyinka waxay muujinayaan snails oo u socdaalaya ilaa 25 mitir 24 saacadood," Hodgeson ayaa sidaas yidhi. Tijaabadan oo socotay 72 saacadood ayaa sidoo kale iftiimisay sida ay xayawaanku u sahamiyaan agagaarkooda, meelaha ay gabaad ka dhigtaan, iyo sida saxda ah ee ay u guuraan.
"Waxaan ogaanay in shilku ay ku socdaan kolonyo, oo ah nooca doofaarka ee slime ee snails kale," ayuu yidhi ecologist. Sababta tani waa mid fudud. Marka marka mollusk uu raaco raad jira, waxa ay la mid tahay simbiriirixinta, Hodgeson waxaa soo xigtay BBC isagoo leh. Tani waa sababta oo ah snailku wuxuu badbaadiyaa tamarta, oo ay suurtagal tahay si weyn. Marka loo eego qiyaasaha, 30 ilaa 40 boqolkiiba baahida tamarta xamaaratada ayaa sabab u ah soo saarista slime.
dulin ayaa la raraa
Natiijooyinka waxaa lagu daray warbixinta "Slime Watch" ee ololaha Ingiriiska La soco gooryaanka sambabada. Tani waxay doonaysaa inay soo jiidato dareenka eyga sida ugu dhakhsaha badan ee dulin Angiostrongylus vasorum uu ku faafi karo snails. Eeydu waxay si fudud u liqi karaan xitaa kuwa ugu yar ee laga helo alaabta carruurtu ku ciyaarto, tusaale ahaan. Dulin-ku-nooleyaashu waxay markaas soo galaan sambabada, waxayna ku xiran tahay darnaanta caabuqa, calaamaduhu waxay u dhexeeyaan qufaca, dhiig-baxa, matag, shuban ilaa dhiig-baxa. Haddii uu jiro tuhun ah in eey uu qabo gooryaanka sambabada, dhakhtarka xoolaha waa in isla markiiba lala tashado - ka dibna cudurka si fudud ayaa loo daweyn karaa.
Dulin-ku-noolaha, oo asal ahaan ka dhaca Faransiiska, Danmark, iyo Ingriiska, ayaa aad iyo aad ugu faafay sannadihii la soo dhaafay, ma aha oo keliya Great Britain. Dieter Barutzki oo ka tirsan shaybaadhka caafimaadka xoolaha ee Freiburg ayaa daabacay daraasad sannadkii 2010-kii, sida laga soo xigtay nooca sambabada ee hadda aad u baahsan, gaar ahaan koonfur-galbeed ee Jarmalka. Dalkan, sidoo kale, snailsku waa marti dhexdhexaad ah oo muhiim ah sidaas darteedna waxay halis u yihiin infekshinka saaxiibka ugu fiican ee ninka.
