Cover Story: Antibiotics have served modern medicine well, but the inexorable trend to resistance poses future challenges. Epidemiological surveillance programs, stewardship, and development of new drugs have collectively met urgent needs to address antibiotic resistance. The report by Villanueva et al. using a CA-MRSA strain, MW2, considered a less studied question: does a bacterium possess mechanisms that actually help it to survive low level exposure with antibiotics (in this case ceftaroline)? Most antibiotics are naturally occurring or derivatives, and so bacteria could possibly have evolved protection against sub-therapeutic concentrations. Identifying if this is the case, and by what mechanism, might help antibiotics work better or lead to promising targets for future adjuvant therapy. Indeed, disruption of two environmental-sensing systems led to dramatically enhanced sensitivity to ceftaroline. View this paper.
