Descrizione
English: 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.

The aggregated material on the cells may be an adaptation to vancomycin, but the distribution suggests not. The background filter is also covered with aggregates. These are very sparse to the upper right of the cells, while the aggregates on the cells appear quite clearly to be concentrated on the side away from this "shadow" effect. This suggests that the aggregates are coarsely sputtered metal from the coating process. Keith Gregg - Curtin University, Western Australia.
