FILE - In a Feb. 1, 2011 file photo, bedbugs are seen next to the tip of a finger in a container from the lab at the National Pest Management Association, during the National Bed Bug Summit in Washington. In a study released Wednesday, May 11, 2011, Canadian scientists detected drug-resistant MRSA bacteria in bedbugs from three hospital patients from a downtrodden Vancouver neighbourhood. Bedbugs have not been known to spread disease, and there's no clear evidence that the five bedbugs found on the patients or their belongings had spread MRSA or a second less dangerous drug-resistant germ. However, bedbugs can cause itching that can lead to excessive scratching. That can cause breaks in the skin that make people more susceptible to these bacteria, noted Dr. Marc Romney, one of the study's authors. less
