Drug-Resistant Flesh-Eating Germs Additional Popular with Superbugs

Sandy Wilson woke up soon after giving birth to her son to discover that she was the victim of a flesh-eating bacteria. More than the course of five many years, it ate away her skin, spleen, gall bladder, appendix, part of her stomach and eventually, all of her intestines. The situation seems out of nowhere and used to be pretty rare, caused by just one type of strep bacteria. But now, drug-resistant superbugs like MRSA can make "flesh-eating" toxins that attack diabetics, obese folks, cancer sufferers and others with weak immune devices...folks who make up a growing portion on the American population.

According to R&D Magazine, to stop the spread doctors cut away dead tissue, but much with the time the infection advances even when it seems it was completely removed. Thanks to the popularity of everything from prescription drugs to anti-bacterial hand soaps, our fear of germs is making those that are capable of seriously harming us even stronger.

"In the first 20 years I practiced, I may have seen one case," said Dr. Alan Bisno, a retired University of Miami expert who has lectured other doctors on this. "Within a very few many years, everybody in the audience had all seen cases."

Wilson's story is gruesome but ultimately happy -- immediately after 5 years, she is finally able to return home being with her son and possibly go back to work. The estimated cost of treatment so far is $5 million, paid for with insurance, then Medicaid, Medicare and disability. But for other people, the story isn't promising. In 2009, a "flesh-eating superbug" killed a father just four hours soon after being admitted to a hospital in Britain. The bacteria is being called "Britain's new horror."

Called necrotizing fasciitis, the disease is a "condition of rapidly spreading infection, usually located in fascial planes of connective tissue that results in tissue necrosis (dead and damaged tissue). The disease occurs infrequently, but it can occur in almost any area on the body. Although many cases have been brought on by group A beta-hemolytic streptococci (Streptococcus pyogenes), most investigators now agree that many different bacterial genera and species, either alone or together (polymicrobial) can cause this disease. Occasionally, mycotic (fungal) species cause necrotizing fasciitis."

Superbugs have become much more common as we've increased our usage of pesticides and anti-bacterial drugs and disinfectants for both ourselves and the animals we raise as food in factory farms. Bacteria rapidly evolve to become resistant to what once would wipe them out. Because several kinds of bacteria can cause necrotizing fasciitis, the possibility of it becoming a much more widespread occurrence is very real.
