The incidence of serious strep infections has risen dramatically in the last three decades, and this increase is largely attributed to the spread around the globe of a single strain of strep known as the invasive M1T1 clone. Researchers at the University of California, San Diego (UCSD) School of Medicine and the University of Wollongong in Australia have discovered that, 30 years ago, a virus infected the strep bacteria ?creating a deadly strain of ?lesh-eating?bacteria that has evolved to produce serious human infections worldwide.
