Kev kho hniav kab noj hniav microbes tsim "superorganism" pawg

TEB CHAWS USA: Ib txoj kev tshawb fawb coj los ntawm cov kws tshawb fawb los ntawm University of Pennsylvania Lub Tsev Kawm Ntawv Kho Hniav Tshuaj tau pom tias cov kab mob microbial ntawm cov kab mob thiab cov fungi pom nyob rau hauv cov hniav lwj tau tiv taus cov tshuaj tua kab mob ntau dua li lawv cov hom sib npaug.

Cov kev tshawb pom, luam tawm nyob rau hauv phau ntawv journal Cov txheej txheem ntawm National Academy of Sciences (PNAS), qhia tias thaum cov kab mob thiab cov kab mob sib sau ua ke, lawv tsim "superorganism" uas tuaj yeem nkag mus thiab dhia hla cov hniav - txawm tias kis mus rau lwm qhov ntawm lub cev.

Yuav luag tsis pom kev

Pom muaj nyob rau hauv cov qaub ncaug ntawm cov menyuam yaus uas muaj cov hniav lwj loj heev, cov kev sib dhos no tuaj yeem ua rau cov hniav zoo.

Hyun (Michel) Koo, tus xibfwb ntawm Penn Dental Medicine thiab tus kws sau ntawv sib koom ua ke ntawm daim ntawv hais tias "Qhov no tau pib nrog qhov yooj yim heev, yuav luag tsis pom kev thaum saib cov qauv qaub ncaug los ntawm cov menyuam yaus uas tsim cov hniav lwj,".

Real-time live microscopy pab kev sim

"Saib hauv qab lub tshuab ntsuas, peb pom cov kab mob thiab cov fungi tsim cov kev sib sau ua ke thiab tsim cov lus tsa suab uas peb tsis tau xav tias lawv yuav muaj: 'zoo li taug kev' thiab 'zoo li dhia' mus. "

Cov txheej txheem tshiab ntawm kev tshawb pom tau los ntawm kev tshawb fawb ntxiv los ntawm cov kws kho mob tom qab hauv Koo pawg, Zhi Ren, tau siv cov tshuaj microscopy uas tso cai rau cov kws tshawb fawb pom tus cwj pwm ntawm cov kab mob nyob hauv lub sijhawm.

Ren yog thawj tus sau ntawm daim ntawv thiab ib feem ntawm thawj pawg ntawm NIDCR T90R90 postdoctoral kev cob qhia kev kawm hauv Penn's Center for Innovation & Precision Dentistry.

"(Cov txheej txheem) qhib qhov muaj peev xwm tshiab los tshawb xyuas qhov kev hloov pauv ntawm cov txheej txheem lom neeg nyuaj," nws hais.

Qhov kev tshawb pom tau coj mus rau ntau qhov kev sim siv lub sijhawm nyob hauv microscopy los kawm txog qhov txuas thiab qhov tshwm sim ntawm kev loj hlob.

"Leaping" microbes kis sai thiab dav

Cov kws tshawb fawb tau tshawb pom tias cov zej zog microbial tau txav mus sai thiab deb - ntawm qhov nrawm ntawm ntau dua 40 microns ib teev ntawm cov hniav zoo li qhov chaw, uas yog piv rau qhov ceev ntawm fibroblasts, ib hom cell hauv tib neeg lub cev koom nrog kev kho mob.

Cov kws tshawb fawb tau soj ntsuam cov kev sib dhos "leaping" ntau dua 100 microns thoob plaws qhov chaw hauv thawj teev ntawm kev loj hlob. Ren hais tias, "Qhov ntawd yog ntau dua 200 npaug ntawm lawv lub cev ntev," Ren hais tias, "ua rau lawv zoo dua rau feem ntau cov vertebrates ntawm lub cev loj."

Vim tias cov khoom sib dhos no pom muaj nyob hauv cov qaub ncaug, tsom rau lawv thaum ntxov tuaj yeem yog lub tswv yim kho mob los tiv thaiv cov hniav lwj, hais tias Koo. "Yog tias koj thaiv qhov kev khi no lossis cuam tshuam kev sib dhos ua ntej nws tuaj txog ntawm tus hniav thiab ua rau muaj kev puas tsuaj, qhov ntawd tuaj yeem yog lub tswv yim tiv thaiv."

Tshaj li cov ntawv thov rau kev kho tus kab mob tshwj xeeb no, cov kws tshawb fawb hais tias, qhov kev tshawb pom tshiab tuaj yeem siv tau rau hauv microbial biology feem ntau.
