Abstract
Tigecycline resistance in Klebsiella pneumoniae results from ramA upregulation that causes the overexpression of the efflux pump, AcrAB-TolC. Tigecycline mutants, derived from Ecl8?ramA, can exhibit a multidrug resistance phenotype due to increased transcription of the marA, rarA, acrAB, and oqxAB genes. These findings support the idea that tigecycline or multidrug resistance in K. pneumoniae, first, is not solely dependent on the ramA gene, and second, can arise via alternative regulatory pathways in K. pneumoniae. © 2012, American Society for Microbiology.
