LiaX is a surrogate marker for cell envelope stress and daptomycin non-susceptibility in .

Daptomycin (DAP) is often used as a first-line therapy to treat vancomycin-resistant infections, but emergence of DAP non-susceptibility threatens the effectiveness of this antibiotic. Moreover, current methods to determine DAP minimum inhibitory concentrations (MICs) have poor reproducibility and accuracy. In enterococci, DAP resistance is mediated by the LiaFSR cell membrane stress response system, and deletion of encoding the response regulator results in hypersusceptibility to DAP and antimicrobial peptides.
