"Antibiotic heteroresistance is a phenomenon in which genetically identical antibiotic susceptible and resistant subpopulations of bacterial cells co-exist, one type of "phenotypic resistance". The relevance of heteroresistance has been unclear, but we show in the bacterium Enterobacter cloacae that a subpopulation resistant to the "last-line" drug colistin can mediate treatment failure in vivo. Furthermore, if this subpopulation is present at a very low level, it can evade detection by current diagnostic tests. These findings highlight the clinical relevance of heteroresistance, which is also observed in fungal pathogens and human cancers."
