This illustration depicts a 3D computer-generated image of a number of drug-resistant Neisseria gonorrhoeae diplococcal bacteria. Note that extending from the organisms’ exterior were type IV pili, or hair-like appendages, which in this case, are used to promote motility for these bacteria, and improve surface adherence. The artistic recreation was based upon scanning electron microscopic imagery. Image credit: U.S. Centers for Disease Control and Prevention.

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.
