Pathogen Interference: Targeting Virulence Factors to Tackle Intracellular Microbes

Infections with Salmonella enterica pose a challenge for antibiotic treatment. In this issue of Cell Chemical Biology, Tsai et al. use a chemical genomics approach to identify dephostatin as an inhibitor of intracellular Salmonella virulence in vitro and in vivo by targeting the two-component systems SsrA-SsrB and PmrB-PmrA.
