methicillin resistant Staphylococcus aureus (MRSA) bacteria

Magnified 20,000X, this colorized scanning electron micrograph (SEM) depicts a grouping of methicillin resistant Staphylococcus aureus (MRSA) bacteria. See PHIL 617 for a black and white view of this image. These S. aureus 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. Retrieve uncompressed archival TIFF version (10.77 megabytes)
