At first glance, this image looks like something pulled from the files of NASA, not NIH. But, no, you are not looking at alien orbs on the rocky surface of some distant planet! This is a colorized scanning electron micrograph of a white blood cell eating an antibiotic resistant strain of Staphylococcus aureus bacteria, commonly known as MRSA.

MRSA stands for methicillin-resistant Staphylococcus aureus, and it’s one nasty bug. You’ve probably heard about the dangers of MRSA infections, but what’s the easiest way to prevent one? Just like with the flu, you should wash your hands – frequently! Personal hygiene is key. And while MRSA infections are more common in people with weakened immune systems, other folks, such as athletes who share towels, are also vulnerable. To learn more about MRSA and how to protect yourself and your loved ones from this increasingly common health risk, go to http://www.nlm.nih.gov/medlineplus/ency/article/007261.htm.
