Meningococcal membrane protein patterns were studied by SDS-PAGE analysis of group A meningococci isolated before and during a large epidemic of group A meningococcal disease in northern Nigeria. No difference was found in the membrane protein patterns of strains isolated before or during the 3 years of the epidemic. Isolates obtained from cases and carriers had similar membrane protein patterns.
