Nyanzvi dzinobva kuUS National Aeronautics and Space Administration (NASA) dzakagumisa kuti International Space Station (ISS), uko kunoshanda vanoongorora muchadenga vatanhatu, izere nehutachiona hwepathogenic.
Mazhinji ema microorganisms anokura pamusoro pechiteshi anozivikanwa kugadzira ese mabhakitiriya uye fungal biofilms, ayo anowedzera kuramba kune mishonga inorwisa mabhakitiriya.
Chikwata cheNASA chakaburitsa mhedzisiro yechidzidzo chitsva-yekutanga yakazara katalogi yehutachiona muakavharwa nzvimbo masisitimu-mumagazini Microbiome. Vatsvagiri vanoti kugona kweaya ma biofilms kutungamira kune microbial corrosion paPasi kunogona zvakare kukuvadza ISS masisitimu nekukonzera kuvharika kwemagetsi.
Hutachiona uhu hunounzwa kuISS nevazivi vemuchadenga hwakafanana neutachiona huri munzvimbo dzekusimbisa muviri, mumahofisi uye muzvipatara zvePanyika. Izvi zvinosanganisira zvinodaidzwa kuti utachiona hunoita mukana hwakadai seStaphylococcus aureus (inowanzowanikwa paganda nemumhuno) uye Enterobacteriaceae (inodyidzana negwara redumbu remunhu). Kunyange vachigona kukonzera kurwara paPasi, hazvizivikanwe kuti vangakanganisa sei vagari veISS.
Pachidzidzo ichi, timu yakashandisa nzira dzetsika dzechinyakare uye nzira dzekutevedzana kwemajini kuti vaongorore masampula epamusoro akaunganidzwa kubva munzvimbo sere paISS, kusanganisira hwindo rekuona, chimbuzi chakaputika nguva pfupi yadarika, zvichikonzera kudonha kwemarita maviri (7,6 galoni) US segment. l) mvura, pamwe nenzvimbo yekurovedza muviri, tafura yekudyira uye yekurara. Sample collection yakaitwa pamusoro pemamishini matatu mukati memwedzi gumi nemana.
