Invasive meningococcal disease (IMD) is a nationally reportable disease in Canada. Since 1985, the Laboratory Centre for Disease Control (LCDC) has enhanced IMD surveillance to correlate case-by-case information provided by the provinces and territories with detailed laboratory studies done at the National Laboratory for Bacteriology at LCDC. This report provides information on IMD from 1 Janua...

C with other infections, such as yellow fever or malaria, awareness of the potential for travelers to contract meningococcal disease is low. Global disease incidence rates, however, may be as high as 1,000/100,000 population in the ‘‘meningitis belt’’ of sub-Saharan Africa and are generally between 100 and 800/100,000 population during epidemics in Africa.1,2 In the United States, the annual in...

Serogroup B Neisseria meningitidis is a frequent cause of invasive meningococcal disease, yet there are no effective vaccines suitable for routine immunisation. Limited efficacy has been shown with meningococcal outer membrane vacccines in children 4 years and older. Here we review the status of current research and consider new approaches to development of meningococcal serogroup B vaccines.

BACKGROUND Neisseria meningitidis serogroup C has emerged as a cause of epidemic disease in Hefei. The establishment of serogroup C as the predominant cause of endemic disease has not been described. METHODS We conducted national laboratory-based surveillance for invasive meningococcal disease during 2000-2010. Isolates were characterized by pulsed-field gel electrophoresis and multilocus seq...

Three cases of meningococcal disease which occurred over a 3 year period in HIV-infected people living in the Wentworth Health Area of Sydney, Australia, are described. None of the 3 had ever received antiretroviral therapy which may, have contributed to development of invasive meningococcal disease.

The relationship between carriage and the development of invasive meningococcal disease is not fully understood. We investigated the changes in meningococcal carriage in 892 military recruits in Finland during a nonepidemic period (July 2004 to January 2006) and characterized all of the oropharyngeal meningococcal isolates obtained (n = 215) by using phenotypic (serogrouping and serotyping) and...

Meningococcal disease is a fulminant infection with an overall mortality of 8%. Mortality is significantly increased with meningococcal septicaemia, particularly when there has been a delay in the diagnosis. The trend from 1985 to 1995 has been an increase in incidence of this disease, and the relative importance of meningococcal disease has also increased following a fall in the incidence of i...

Invasive meningococcal disease (IMD) is a severe bacterial infectious disease with high mortality and morbidity rates worldwide. In recent years, industrialised countries have implemented vaccines targeting IMD in their National Immunisation Programmes (NIPs). In 2002, the Netherlands successfully implemented a single dose of meningococcal serogroup C conjugate vaccine at the age of 14 months a...

BACKGROUND Deprivation is associated with an increased risk of invasive Neisseria meningitidis disease, but little is known about the relationship between deprivation and asymptomatic carriage of N. meningitidis. This analysis was conducted to examine the relationship between meningococcal carriage and deprivation. METHODS As part of a rapid meningococcal carriage prevalence study conducted i...
