  1. Changing epidemiology of meningococcal invasive disease in the Czech Republic caused by new clone Neisseria meningitidis C : 2a : P1.2 (P1.5), ET-15/37.

    Article - En anglais

    Invasive meningococcal disease, caused mainly by Neisseria meningitis B. occurred only sporadically in Czech Republic for a long period, and the use of meningococcal polysaccharide vaccine was never indicated.

    This situation changed in 1993, when a new meningococcal clone appeared.

    By means of sero/subtyping (using Whole Cell ELISA) Neisseria meningitidis C : 2a : P1.2 (P1.5) was quickly revealed to be the causative agent of this unusual epidemiological situtation.

    ET typing by multilocus enzyme electrophoresis showed the prevalence of the ET-15 electrophoretic type, which belongs to the ET-37 complex.

    This new clone had never been identified in the Czech Republic at least since 1973.

    The new clone caused an increase in the incidence of invasive meningococcal disease in the army campuses in the eastern part of the country and low local invasive meningococcal diseases outbreaks in civilian population at the beginning of 1993.

    In May 1993, the highest age-specific incidence in the most affected district was found in the age of 15-19 years (52.1 per 100 000), while the respective age specific incidence for the whole Czech Republic was 1.9 per 100 000.

    The vaccination campain started in the most affected district at the beginning of June 1993 and was focused on the most affected age group, 15-19 years.

    After this targeted vaccination campaign the number of invasive meningococcal disease decreased in this district statistically significantly.

    The new clone Neis...
