Blocking a key molecule of Yersinia pestis, the bacterium that causes plague, may help slow the progression of the pneumonic form of the disease and allow antibiotics time to work, according to new research conducted at Washington University School of Medicine, in St Louis, Mo (Lathem WW et al. Science. 2007;315:509-513). Y pestis is best known for causing the Black Death in the Middle Ages, when it killed a third or more of the European population.
