© Neisseria meningitidis inhaled, infects upper airways.

@ Bacteria enter the bloodstream and are circulated throughout the body.

© The bacteria lodge in the skin and cause petechiae.

@ Bacteria on the meninges causes meningitis.

© Lysing bacteria in the circulation release endotoxin, producing shock.

© Inflammatory response in meninges can damage nerves of hearing causing deafness and obstruct the flow of cerebrospinal fluid causing increased pressure inside the brain.

@ Bacteria exit with respiratory secretions.

Epidemiology

Prevention and treatment

Mild cold followed by headache, fever, pain, stiff neck and back, vomiting, petechiae 1 to 7 days

Neisseria meningitidis, the meningococcus; a Gram-negative diplococcus

Meningococci adhere by pili, colonize upper respiratory tract, enter bloodstream; carried to meninges and spinal fluid; inflammatory response obstructs normal outflow of fluid; increased pressure caused by obstructed flow impairs brain function; damage to motor nerves produces paralysis; endotoxin release causes shock Close contact with a case or carrier; inhalation of infectious droplets; crowding and fatigue predispose to the disease

Polysaccharide vaccine against types A, C, W135, and Y used to immunize high-risk populations; rifampin given to those exposed. Penicillin, ceftriaxone, for treatment
