Amagciwane aqala ukumelana nemithi ngokuhamba kwesikhathi. Lena inkinga enkulu ebhekene nemboni yezokunakekelwa kwempilo. Ukuvela kwamagciwane ayanda ukumelana nama-antibiotic kungasho izifo okunzima noma okungenakwenzeka ukukwelapha, okuholela ekufeni kwabantu abagulayo. Ososayensi abasebenzela ukwenza ukuphila ku-Mars basize ekuxazululeni inkinga yamagciwane amelana nemithi.
Enye yezinselele zokuphila ku-Mars ukuthi kune-perchlorate emhlabathini. Lezi zinhlanganisela zingase zibe yingozi kubantu.
Abacwaningi be-Institute of Biology e-Leiden University (Netherlands) basebenzela ukwakha amagciwane angakwazi ukubola abe yi-chlorine nomoya-mpilo.
Ososayensi baye baphindaphinda amandla adonsela phansi e-Mars besebenzisa umshini wokumisa okungahleliwe (RPM), ozungezisa amasampula ezinto eziphilayo ngezimbazo ezimbili ezizimele. Lo mshini ushintsha njalo ngokungahleliwe umumo wamasampuli ebhayoloji angenawo amandla okujwayela amandla adonsela phansi angaguquki ohlangothini olulodwa. Umshini ungalingisa amandla adonsela phansi ayingxenye ngezigaba phakathi kwamandla adonsela phansi avamile, njengaseMhlabeni, kanye nokungabi nesisindo okuphelele.
Amagciwane akhule ngokwengxenye amandla adonsela phansi ayacindezeleka ngoba awakwazi ukukhipha imfucuza ebazungezile. Kuyaziwa ukuthi amagciwane enhlabathini i-Streptomycetes iqala ukukhiqiza ama-antibiotic ngaphansi kwezimo zokucindezeleka. Ososayensi baye baqaphela ukuthi ama-70% emithi elwa namagciwane esiyisebenzisela ukwelapha njengamanje aphuma kuma-streptomycetes.
Ukukhula kwamabhaktheriya emshinini wokumisa okungahleliwe kungaholela esizukulwaneni esisha ngokuphelele semithi elwa namagciwane lapho amabhaktheriya angenawo ukuzivikela. Lokhu kutholakala kubalulekile ngoba ukwakhiwa kwama-antibiotic amasha kungenye yezindawo ezibaluleke kakhulu ocwaningweni lwezokwelapha.
