Study Notes
Meningococcal Transmission and Colonization
- Humans are the only natural hosts for meningococci.
- Meningococci are transmitted through airborne droplets.
- The organisms colonize the membranes of the nasopharynx.
- Colonization of the nasopharynx leads to meningococci becoming part of the transient flora of the upper respiratory tract.
- Carriers of meningococci are usually asymptomatic.
Meningococcal Infection and Dissemination
- From the nasopharynx, meningococci can enter the bloodstream.
- Infection can spread to specific sites, such as the meninges or joints.
- Meningococci can also be disseminated throughout the body, causing meningococcemia.
