Enhanced Efflux Pump Expression in Candida Mutants Results in Decreased Manogepix Susceptibility.

abstract：:The Cpx stress response is widespread among Enterobacteriaceae We previously reported a mutation in cpxA in a multidrug-resistant strain of Klebsiella aerogenes isolated from a patient treated with imipenem. This mutation yields a single-amino-acid substitution (Y144N) located in the periplasmic sensor domain of CpxA....
