Bubonic plague is an infection of the lymphatic system usually resulting from the bite of an infected flea. The bacteria rapidly spread to the lymph nodes and multiply. Yersinia pestis can resist phagocytosis and even reproduce inside phagocytes and kill them. As the disease progresses the lymph nodes can hemorrhage and become necrotic. Bubonic plague can progress to the lethal [[septicemic plague]] in some cases. |
