Study illuminates how the plague bacteria causes disease

...pathogen's Achilles heel--an attractive target for antibacterial or anti-virulence compounds." "We were quite excited to see such a critical and unexpected factor in the virulence of Yersinia--a bacteria historically responsible for some of the worst diseases," he added. Although improvements in sanitation have ...

Nanotech tools yield DNA transcription breakthrough
