Plague Bacteria

Plague is a known worldwide killer of men, women, and children. It takes three forms: pneumonic, bubonic, and septicemic. Plague causes a painful, relatively quick death that often involves vomiting, bleeding, and gangrene of the skin. Fortunately, today's antibiotics can kill the Yersinia pestis bacteria and save its victim upon early detection.
