Stephanie M. Reeve et al. identified two plasmid-borne genes that confer high-level resistance to trimethoprim for the first time in MRSA isolates from U.S. hospitals; a series of charged propargyl-linked antifolates overcome this resistance via direct inhibition of the acquired resistance elements. This colorized scanning electron micrograph depicts a grouping of MRSA bacteria. These bacteria are methicillin-resistant, and are from one of the first isolates in the U.S. that showed increased resistance to vancomycin as well. Note the increase in cell wall material seen as clumps on the organisms’ surface. Image credit: Janice Haney Carr / Public Health Image Library / CDC.
