Proteolytic processing of the Yersinia pestis YapG autotransporter by the omptin protease Pla and the contribution of YapG to murine plague pathogenesis. Through this work, they have made an important discovery about a molecule secreted by Y. pestis and other bacteria that helps defeat the host's immune defenses, allowing the bacteria to infect its hosts. Retracing the evolutionary steps between these two Yersinia species may ultimately furnish a historical model for the sudden emergence of new human disease agents. Victims of the plague would often die within a few days and the horrific symptoms would make these final days absolutely terrible. Despite these profoundly different pathogenesis strategies, the two bacteria are very closely related phylogenetically. Bubonic plague can usually be successfully treated with various antibiotics: gentamicin (Garamycin) streptomycin levofloxacin (Levaquin) ciprofloxacin (Cipro) doxycycline (Vibramycin).
