Khubaro ka socota maamulka hawada sare ee Maraykanka (NASA) ayaa soo gabagabeeyey in xarunta hawada sare ee caalamiga ah (ISS), halkaas oo lix cirbixiyeen ay ka shaqeeyaan, ay si dhab ah uga buuxaan bakteeriyada caabuqa.
Qaar badan oo ka mid ah noolayaasha ku koraya oogada saldhigga ayaa la og yahay inay sameeyaan labadaba bakteeriyada iyo fungal biofilms, kuwaas oo kordhiya caabbinta antibiyootiga.
Koox NASA ah ayaa daabacday natiijooyinka daraasad cusub - buuggii ugu horreeyay ee dhamaystiran ee microbes ee nidaamyada bannaan ee xiran - joornaalka Microbiome. Cilmi-baadhayaashu waxay sheegeen in awoodda biofilms-yadan ay u horseedi karaan daxalka microbial on Earth waxay sidoo kale dhaawici karaan kaabayaasha ISS iyagoo keenaya xannibaadyo farsamo.
Jeermiskan ay cirbixiyeenadu keenaan ISS waxay la mid yihiin jeermiska ku jira jimicsiga, xafiisyada iyo cisbitaalada Dunida. Kuwaas waxaa ka mid ah waxa loogu yeero cudur-sidaha fursada sida Staphylococcus aureus (oo inta badan laga helo maqaarka iyo marinnada sanka) iyo Enterobacteriaceae (oo la xidhiidha mareenka caloosha iyo mindhicirka ee bini'aadamka). In kasta oo ay cudur ku keeni karaan dhulka, ma cadda sida ay u saamayn karaan dadka deggan ISS.
Daraasadda, kooxdu waxay adeegsatay hababka dhaqanka ee soo jireenka ah iyo farsamooyinka isku xigxiga hidaha si ay u falanqeeyaan muunado dusha laga soo ururiyay siddeed goobood oo ku yaal ISS, oo ay ku jiraan daaqad indho-indhayn ah, musqul dhawaan dillaacay, taasoo keentay daadinta laba gallon (7,6 gallon) gudaha Qaybta US. Tusaalaha ururinta waxa la fuliyay saddex hawlood oo socday muddo 14 bilood ah.
