Iintsholongwane zikhula ukumelana namachiza ekuhambeni kwexesha. Le yingxaki enkulu ejongene neshishini lezempilo. Ukuvela kweebhaktheriya ezixhathisa i-antibiotic-resistant kunokuthetha usulelo okunzima okanye olungenakwenzeka ukunyanga, olukhokelela ekufeni kwabantu abagulayo. Izazinzulu ezisebenzela ukwenza ubomi bube khona kuMars zinokunceda ekucombululeni ingxaki yeentsholongwane ezikwaziyo ukumelana namayeza.
Omnye weengxaki zobomi kuMars kukuba kukho iperchlorate emhlabeni. Ezi khompawundi zinokuba yingozi ebantwini.
Abaphandi abavela kwiZiko leBhayoloji kwiYunivesithi yaseLeiden (eNetherlands) basebenza ekudaleni iibhaktheriya ezinokubola i-perchlorate kwi-chlorine kunye ne-oxygen.
Izazinzulu ziye zaphindaphinda umxhuzulane weMars zisebenzisa umatshini wokumisa ngokungakhethiyo (RPM), ojikelezisa iisampulu zebhayoloji ecaleni kweezembe ezimbini ezizimeleyo. Lo matshini uhlala utshintsha ngokungenamkhethe ukuqhelaniswa neesampulu zebhayoloji ezingakwaziyo ukuziqhelanisa nomxhuzulane oqhubekayo kwicala elinye. Umatshini unokulinganisa umxhuzulane ngokwezigaba phakathi komxhuzulane oqhelekileyo, njengaseMhlabeni, kunye nobunzima obupheleleyo.
Iintsholongwane ezikhuliswe kumxhuzulane onganeno ziye zibe noxinzelelo ngenxa yokuba azikwazi ukukhupha inkunkuma ezingqongileyo. Kuyaziwa ukuba iibhaktheriya zomhlaba iStreptomycetes ziqala ukuvelisa i-antibiotics phantsi kweemeko zoxinzelelo. Izazinzulu ziye zaqaphela ukuba i-70% yamayeza okubulala iintsholongwane esiwasebenzisayo ngoku kunyango aphuma kwi-streptomycetes.
Ukukhula kwebhaktheriya kumatshini wokumisa ngokungakhethiyo kunokukhokelela kwisizukulwana esitsha ngokupheleleyo samayeza okubulala iintsholongwane apho ibhaktheriya ayinakukhuseleka. Oku kufunyaniswe kubalulekile kuba ukudalwa kwamachiza amatsha okubulala iintsholongwane yenye yezona ndawo zibalulekileyo zophando lwezonyango.
