Chapel Hill NC (SPX) Feb 13, 2015
For decades, scientists have thought the bacteria that cause the bubonic plague hijack host cells at the site of a fleabite and are then taken to the lymph nodes, where the bacteria multiply and trigger severe disease. But UNC School of Medicine researchers discovered that this accepted theory is off base. The bacteria do not use host cells; they traffic to lymph nodes on their own and not in great numbers. In fact, most of the plague-causing bacteria - called Yersinia pestis - get trapped in a bo ... read more
