Meningococcemia is a life-threatening infection that occurs when the meningococcus, Neisseria meningitidis, invades the blood stream. Bleeding into the skin (petechiae and purpura) may occur. The tissue in areas may die (become necrotic or gangrenous). If the person survives, the areas heal with scarring.
