Summary

Why is it that most strains of Staphylococcal aureus bacteria live harmlessly on the skin or in the nose of humans whereas a few strains become invasive and cause serious disease? In his Perspective, Lipsitch discusses new findings ( Day et al.) suggesting that the very characteristics that make bacteria efficient at colonizing their hosts also render them better at invading host tissue and causing disease.
