Septicemic plague

Septicemic (or septicaemic) plague is a deadly blood infection by yersinia pestis, a gram-negative bacterium.

Pathophysiology
The disease can result from bubonic and pneumonic plague when bacteria enter the blood from the lymphatic and respiratory systems, respectively. Like other forms of gram-negative sepsis, septicemic plague can cause disseminated intravascular coagulation (DIC), and is frequently fatal.
