BACKGROUND In the African meningitis belt, Neisseria meningitidis serogroup W135 has emerged as a cause of epidemic disease. The establishment of W135 as the predominant cause of endemic disease has not been described. METHODS We conducted national laboratory-based surveillance for invasive meningococcal disease during 2000-2005. The system was enhanced(More)
We describe the epidemiology of invasive meningococcal disease in South Africa from August 1999 through July 2002, as reported to a laboratory-based surveillance system. Neisseria meningitidis isolates were further characterized. In total, 854 cases of laboratory-confirmed disease were reported, with an annual incidence rate of 0.64/100,000 population.(More)
We characterized five Neisseria meningitidis serogroup C isolates from a Chicago outbreak of meningococcal disease that occurred in 2003 among a community of men who have sex with men. Isolates from this outbreak were identical to each other but distinct from the clone that caused a similar outbreak in Canada in 2001.
The proportion of meningococcal disease in the United States, South Africa, and Israel caused by Neisseria meningitidis serogroup Y (NmY) was greater than the worldwide average during the period 1999-2002. Genotypic characterization of 300 NmY isolates by multilocus sequence typing, 16S rRNA gene sequencing, and PorA variable region typing was conducted to(More)
