ONLINE COVER Beating MRSA with a One-Two Punch. The cover shows colonies of methicillin-resistant Staphylococcus aureus (MRSA) grown in agar spiked with different antibiotics. Resistance of bacteria to β-lactam antibiotics, a mainstay of infectious disease treatment, continues to emerge and has resulted in MRSA becoming a major cause of mortality in hospitals. Tan et al. now show that a small molecule that blocks FtsZ, a vital component of MRSA's replication apparatus, not only stops the pathogen from growing but also renders it once again sensitive to β-lactam antibiotics. This one-two punch may be a valuable therapeutic strategy for combating MRSA in hospitals. [CREDIT: C. BICKEL/SCIENCE TRANSLATIONAL MEDICINE]
