is a major cause of bacterial meningitis and a Neisseria meningitidis considerable health problem in the 25 countries of the ‘African Meningitis Belt’ that extends from Senegal in West Africa to Ethiopia in the East. Approximately 80% of cases of meningococcal meningitis in Africa have been caused by strains belonging to capsular serogroup A. After the introduction of a serogroup A conjugate po...

The objective of this study was to investigate whether it is possible to use a lateral (profile) photograph to determine the underlying skeletal Class and which reference points of the angle of convexity are most suitable for this purpose. Profile photographs and lateral cephalographs included in the baseline data for 180 orthodontic patients were retrospectively evaluated. The subjects were as...

On 25 June 2013, Germany reported three cases of invasive meningococcal disease (IMD) among men who have sex with men (MSM) caused by N. meningitidis serogroup C. All three isolates were serogroup C, PorAVR1: 5-1; PorA-VR2: 10-8 and FetA: 3-6 and confirmed as ST-11/ET-15. On 26 June, Belgium retrospectively reported (via EPIS-VPD) a single case of IMD in a homosexual male diagnosed in March 201...

The serogroup A meningococcal conjugate vaccine MenAfriVac has the potential to confer herd immunity by reducing carriage prevalence of epidemic strains. To better understand this phenomenon, we initiated a meningococcal carriage study to determine the baseline carriage rate and serogroup distribution before vaccine introduction in the 1- to 29-year old population in Burkina Faso, the group cho...

BACKGROUND The serogroup A conjugate meningococcal vaccine, MenAfriVac, was introduced in mass vaccination campaigns in December 2010 in Burkina Faso, Mali and Niger. In the coming years, vaccination will be extended to other African countries at risk of epidemics. To document the molecular characteristics of disease-causing meningococcal strains circulating in the meningitis belt of Africa bef...

The sneaky meningococcus is a bacterium that can cause terrible disease. Development of an effective vaccine has been extremely difficult. Meningococcal vaccines developed in the 1990s are based on bacterial capsule, shield protects bacteria and used to instruct our body combat this These work against four types meningococcus: A, C, W, Y. However, they do not B. Scientists had invent completely...

The reservoir for Neisseria meningitidis (Nm) is the human oropharynx. Implementation of Nm serogroup C (NmC) glycoconjugate vaccines directly reduced NmC carriage. Prophylactic vaccines are now available to prevent disease caused by the five major Nm disease causing serogroups (ABCWY). Nm serogroup B (NmB) vaccines are composed of antigens that are conserved across Nm serogroups and therefore ...

The cross-reactivity of PorA-specific antibodies induced by a monovalent P1.7-2,4 (MonoMen) and/or a hexavalent (HexaMen) meningococcal B outer membrane vesicle vaccine (OMV) in toddlers and school children was studied by serum bactericidal assays (SBA). First, isogenic vaccine strains and PorA-identical patient isolates were compared as a target in SBA, to ensure that the vaccine strains are r...
