Meningitides-Human nasopharynx is only reservoir of meningococcus. (N. meningitidis)* Most important source- carriers are the most imp source, not clinical cases.* They are arranged in pairs with adjacent sides flattened--7 half moon shaped.* Transport medium--Stuart's medium.* Blood agar, chocolate agar and Muller-Hinton agar are the media commonly used for culturing meningococci.* Age group- 3 month-5 years* Serotype- total 13, out of which serotype A, B, C are most important# Serotype A- Epidemics# Serotype B- Both epidemic and local outbreaks# Serotype C- Local out breaks* Chemoprophylaxis has been suggested for close contacts.* Is DOC for prophylaxis.* Ceftriaxone > ciprofloxacin > Rifampicin
