Muaj paw prints qhov twg dev nyob. Txawm miv nyob qhov twg, muaj plaub hau. Nco ntsoov: tsiaj ua av. Tab sis peb cov phooj ywg plaub-legged puas muaj kev nyab xeeb? Ib tus kws kho mob microbiologist tshawb xyuas cov lus nug no.
"Muaj ntau yam kab mob sib kis uas koj yuav tsum tau ceev faj nrog cov tsiaj," hais tias xibfwb Dirk Bockmühl los ntawm Rhein-Waal University of Applied Sciences. Rau "RTL" hom "Stern TV", nws thiab nws pab neeg tau tshuaj xyuas seb cov tsiaj txhu thiab kev nyiam huv yog sib cais.
Txhawm rau ua qhov no, Bockmühle pab pawg tau ntsuas cov kab mob hauv cov tsev neeg nrog tsiaj. Piv txwv li ntawm qhov chaw los yog cov khoom uas cov tsiaj tuaj rau hauv kev sib cuag tsis tu ncua. Tsis tas li ntawd, rau qhov kev sim, cov tswv tsiaj hnav cov hnab looj tes tsis muaj roj hmab thaum sib cuam tshuam nrog lawv cov tsiaj. Hauv chav kuaj, thaum kawg tau soj ntsuam seb muaj pes tsawg tus kab mob, cov kab mob, thiab cov kab mob plab hnyuv tau nyob hauv hnab looj tes.
Tsiaj thiab Kev Tu Kom Huv: Miv Ua Qhov Zoo Tshaj Plaws
Qhov tshwm sim: cov kws tshawb fawb pom cov kab mob ntau tshaj plaws ntawm cov hnab looj tes ntawm cov pob kws nab tus tswv nrog 2,370 daim tawv nqaij kab mob fungal ib square centimeter ntawm hnab looj tes. Kuj tseem muaj cov kab mob loj heev ntawm cov hnab looj tes ntawm tus tswv dev thiab nees: 830 thiab 790 ib square centimeter, feem. Miv, ntawm qhov tod tes, muab qhov ntsuas qhov ntsuas tsis pom tseeb.
Tab sis cov kab mob ntawm daim tawv nqaij puas txaus ntshai rau peb tib neeg? Feem ntau, cov kab mob yuav tsum tau "qhov rooj" mus rau hauv lub cev, piv txwv li, qhov txhab lossis qhov ncauj. Nws txawv ntawm daim tawv nqaij fungi. Bockmühl: "Cov kab mob ntawm daim tawv nqaij yog zoo nkauj npaum li cov kab mob uas tuaj yeem kis tau rau ntawm daim tawv nqaij noj qab haus huv." Yog li ntawd, microbiologist qhia ceev faj.
Tab sis cov kws tshawb fawb tsis tsuas yog kuaj pom cov kab mob ntawm daim tawv nqaij ntawm cov hnab looj tes, tab sis kuj muaj cov kab mob hauv plab uas tuaj yeem ua rau raws plab thiab ntuav nyob rau qee qhov xwm txheej.
Cov tsiaj puas muaj kev nyab xeeb?
"Hauv ib tus neeg mob - ib qho tuaj yeem hais ntxiv txog qaib lossis cov noog feem ntau - peb pom Enterobactereacen, uas tej zaum yuav muaj kab mob paug," Bockmühl hais. Tib yam siv ntawm no: ceev faj! Vim hais tias, raws li tus xibfwb hais tias: "Yog tias kuv tau ntsib nrog cov quav tsiaj lossis nrog cov chaw uas muaj cov quav, ces kuv tuaj yeem noj cov kab mob thiab ua rau lawv mob."
Tab sis tam sim no cov tsiaj txhu puas muaj kev phom sij tiag tiag? Andreas Sing, tus kws tshaj lij hauv microbiology thiab kis kab mob ntawm Bavarian State Office for Health and Food Safety hais tias "Yog tias koj tau txais tus tsiaj, koj yuav tsum paub tias koj tab tom yuav koj tus kheej muaj kev pheej hmoo,"
Cov kws tshawb fawb coj los ntawm Jason Stull los ntawm Ohio State University tau tshawb fawb nrog pab pawg hauv 2015. "Hauv cov neeg tsis cev xeeb tub uas muaj lub cev tiv thaiv kab mob noj qab haus huv ntawm hnub nyoog 5 txog 64 xyoos, kev pheej hmoo ntawm tus tsiaj muaj kab mob tsawg," lawv sau. Rau cov neeg uas tsis koom nrog pab pawg no, piv txwv li, cov menyuam yaus, tus tsiaj yuav ua rau muaj kev pheej hmoo rau kev noj qab haus huv.
Tias yog vim li cas cov kws tshawb fawb pom zoo kom ntxuav koj txhais tes tsis tu ncua thaum cuam tshuam nrog cov tsiaj, hnav hnab looj tes thaum tshem cov khib nyiab los yog ntxuav cov thoob dej yug ntses, thiab muaj cov tsiaj tsis tu ncua los ntawm kws kho tsiaj.
