Pali zifukwa zambiri zokhalira kutali ndi mayiyo m'njira zazifupi kwambiri pa sitima yapansi panthaka. Osachepera mwawo ndi majeremusi omwe akutsimikiza kuti akupaka pampando wonsewo. Kodi majeremusi a thukuta amenewo angakuvulazenidi? Nanga bwanji za malo ena onse ngati ma handrails ndi makina tikiti? Kodi izo ndi zoipa kwathunthu, nazonso? Mwamwayi, asayansi anali ndi chidwi chokwanira kuti apeze aliyense (popeza tonse tatha kale).

Ofufuza kuchokera ku Harvard T.H. Chan School of Public Health idayesa magalimoto kuchokera kumayendedwe atatu apansi panthaka ku Boston kuti adziwe kuti ndi mitundu yanji ya tizilombo tating'onoting'ono tomwe timadutsana. Nzosadabwitsa kuti adapeza mipando, makoma, ndi mitengo ya magalimoto kuphatikizapo zowonetsera ndi makoma pafupi ndi makina a tikiti-inde, pafupifupi malo onse - anali ophimbidwa ndi tizilombo toyambitsa matenda. Gawo lodabwitsali linali kuti nsikidzi zambiri zomwe zimafalikira sizinali "zoyipa" - kutanthauza kuti sizinatetezedwe ndi maantibayotiki ndipo sizinakhale ndi zovuta zina. M'malo mwake, ofufuza adati madera oyenda pansi panthaka omwe adaswedwa anali ocheperako pama tizilombo tosautsa tomwe timapezeka m'matumbo mwanu kale. (Whew, and ew!) Kuphatikiza apo, mwadzazidwa kale ndi majeremusi-3D Bacteria Maps Prove It.

"Anthu athanzi sayenera kuda nkhawa," akutero Tiffany Hsu, wolemba kafukufuku komanso wothandizira kafukufuku pa dipatimenti ya biostatistics pasukuluyi. "Zimbulu zambiri zomwe zimapezeka zimapezeka pakhungu lamunthu kapena pakamwa, motero anthu ambiri atha kuzinyamula." Komabe, kusamba m'manja mutakwera sitima yapansi panthaka sikungapweteke, akuwonjezera. (Kumbali ina, pali tizilombo toyambitsa matenda tomwe tapezeka tikubisalira m’madziwe osambira.)

Hsu ndi anzawo zomwe apeza, zomwe zikufalitsidwa sabata ino m'magazini ya American Society for Microbiology mSystems.

Ofufuzawo apezanso mitundu yosiyanasiyana ya tizirombo m'malo osiyanasiyana. Tizilombo toyambitsa matenda a pakhungu ndi m'kamwa timene timafalikira poyetsemula kapena kukhudza tinkapezeka tambirimbiri pamitengo yapansi panthaka, ndipo pamipando pali tizilombo toyambitsa matenda. Mawu oti "tizilombo tating'onoting'ono tamkazi" atha kukupangitsani kuti muzanjenjemera, koma sizitanthauza kuti nyini ya wokwerayo idalumikizana ndi khungu ndi mpando. Mitundu yamtundu imeneyi imatha kudutsa pazovala. Ndipo zingatenge zambiri kuti akupatseni matenda, akutero a Hsu. Tizilombo toyambitsa matenda timayenera kukhalabe amoyo, kunyamulidwa ndi zovala zanu m'dera momwe tingapulumukire (motsutsana, titi, mkono wanu), kenako kupikisana ndi tizirombo tina kuti tipeze malo m'gulu la tizilombo toyambitsa matenda. (Inde, pepani kunena kuti muli ndi nsikidzi nthawi zonse.) Pali malo ena otentha ngakhale kuti ali ndi majeremusi ndi mabakiteriya ambiri kuposa momwe mungafunire kudziwa-phunzirani za zinthu 10 zomwe mwina simukadafuna ' sindikufuna kugawana.)

Mfundo yofunika: Ngakhale sitima yapansi panthaka ili ndi tizilombo tating'onoting'ono, sikuti mudzatenga majeremusi azimayi ena. "Pakadali pano, zikuwoneka kuti sangathe kusamutsidwa," akutero Hsu. "Khungu lathu ndi chitetezo cha mthupi zimapereka chitetezo chachikulu!" Zabwino kudziwa, koma palibe amene angakudzudzuleni posankha kuyimilira mpaka nthawi ina.
