It afflicts nearly one million of the 23 million Americans who undergo surgery annually, especially infants and the elderly...
...study was motivated by Hiramatsu's 1996 discovery of vancomycin-resistant staphylococcus aureus (VRSA) in a four-month-old male infant suffering from staphylococcus aureus infection after open-heart surgery. The patient failed to respond to vancomycin therapy and was cured only with a combination of other antibiotics. The strain was named Mu50 and became known as the world's first case of VRSA...
...Hiramatsu also discovered that several strains of staphylococcus aureus--namely the Mu3 strain--had the potential of developing into VRSA. Hiramatsu reported that after repeated treatment with vancomycin, Mu3 developed a resistance level equal to Mu50, the VRSA strain. With each dosage of vancomycin the doctor prescribed, the more resistant the population grew, until it became just steps away from full-blown resistance...
