Akatswiri ochokera ku US National Aeronautics and Space Administration (NASA) atsimikiza kuti International Space Station (ISS), komwe openda nyenyezi asanu ndi mmodzi amagwira ntchito, ili ndi mabakiteriya ambiri oyambitsa matenda.
Tizilombo tambiri tating'onoting'ono timene timamera pamtunda wa stationyo timadziwika kuti timapanga ma biofilm a bakiteriya komanso mafangasi, omwe amawonjezera kukana kwa maantibayotiki.
Gulu la NASA lidafalitsa zotsatira za kafukufuku watsopano - kabukhu kakang'ono kambiri ka tizilombo toyambitsa matenda m'malo otsekedwa - mu nyuzipepala ya Microbiome. Ofufuzawo akuti kuthekera kwa ma biofilms awa kuti atsogolere ku dzimbiri padziko lapansi kungawonongenso maziko a ISS poyambitsa kutsekeka kwamakina.
Majeremusi awa obweretsedwa ku ISS ndi oyenda mumlengalenga ndi ofanana ndi majeremusi omwe ali m'malo ochitira masewera olimbitsa thupi, maofesi ndi zipatala zapadziko lapansi. Izi zikuphatikizapo tizilombo toyambitsa matenda otchedwa mwayi monga Staphylococcus aureus (omwe amapezeka pakhungu ndi m'mphuno) ndi Enterobacteriaceae (ogwirizana ndi thirakiti la m'mimba). Ngakhale angayambitse matenda Padziko Lapansi, sizikudziwika momwe angakhudzire anthu okhala ku ISS.
Pa kafukufukuyu, gululi lidagwiritsa ntchito njira zachikhalidwe komanso njira zotsatsira ma genetic kusanthula zitsanzo zapamtunda zomwe zasonkhanitsidwa kuchokera m'malo asanu ndi atatu pa ISS, kuphatikiza zenera lowonera, chimbudzi chomwe chaphulika posachedwa, ndikupangitsa kutayikira kwa magaloni awiri (malita 7,6) mu Gawo la US. l) madzi, komanso malo ochitira masewera olimbitsa thupi, tebulo lodyera ndi malo ogona. Kusonkhanitsa zitsanzo kunachitika maulendo atatu pa miyezi 14.
