That's really cool! In a random test when I was working in the hospital, I was found to have MRSA, and was treated. We also randomly checked fingernails, and that's when the hospital made rules against fake nails. We had lots of pseudomonas in the unit.

Why do I keep reading these articles?
They have some wrongnesses.
MORE than 15% of people carry staph on their skin or elsewhere, and any staph can potentially be a methicillin resistant strain; it is more likely to be so in areas where antibiotics are used a lot, like healthcare facilities and animal feedlots or poultry-raising operations. Many carry it nasally.
The DNA testing revealed it was likely to have been introduced from one source, but not certainly. And they shotgun tested anyway, which they could have done without the DNA test.
That testing is better at ruling OUT a nosocomial than ruling it IN.
