Meningococcal clone ET-15/37, which appeared as a new one in the Czech Republic in 1993, caused an emergency epidemiological and clinical situation in invasive meningococcal disease, characterized by a high fatality rate (20%) compared to the "normal" fatality rate due to "non ET-15/37" strains. Morbidity rate increased since the first year of the new clone(More)
In spite of a large collection of MAbs used for the whole-cell ELISA (WCE) in the National Reference Laboratory for Meningococcal Infections in Prague 50-80% of N.meningitidis strains isolated in the Czech Republic remained non-typable (NT) and/or non-subtypable (NST). A project focused on the problem of NT/NST N.meningitidis was started and the new(More)
In the Slovak Republic the incidence and mortality of invasive meningococcal disease increased after 1995 when the new meningococcal clone of Neisseria meningitidis C:2a:P1.2,P1.5, ET-1.5/37 emerged. The new clone spread between 1995 and 1998 throughout the whole country. Morbidity of invasive meningococcal disease was 1.6/100,000 of the population and(More)
The purpose of this paper was to present the current knowledge on the prevention of group B streptococcus (GBS) neonatal infections and the status of prevention policies in European countries and to present the DEVANI pan-European program, launched in 2008. The aim of this program was to assess the GBS neonatal infection burden in Europe, to design a new(More)
The nationwide prospective questionnaire study of cases and controls was implemented during the period from October 1996 till May 1998. Thirty-nine districts participated (= 54.2% of district hygiene stations) and 107 invasive meningococcal diseases were included in the study (= 76.9% of diseases recorded during the given period in the Czech Republic by(More)
Cytokine production was determinedin vitro after stimulation with three differentNeisseria meningitidis (NM) strains. Virulent NM B strain isolated from a patient with mild course of invasive meningococcal disease (IMD) elicited higher cytokine production than NM B and NM C hypervirulent strains isolated from patients with moderate and fatal course of IMD,(More)
The study objective is to present results of clonal analysis of Neisseria meningitidis isolates from invasive meningococcal disease in the Czech Republic in 1993-2005. The method of multilocus sequence typing (MLST) revealed genetic heterogeneity of serogroup B isolates and homogeneity of serogroup C isolates. Three clonal sequence type complexes (STC-18,(More)
The authors analyzed the incidence of meningococcal diseases in the West Bohemian region in 1982-1996. The draw attention to changes of clinical and epidemiological characteristics of the disease which appeared in 1994 in conjunction with a new invasive clonus of Neisseria meningitidis C:2a:P1.2, P1.5, ET-15/37. While in 1982-1993 invasive meningococcal(More)
A new epidemiological situation for invasive meningococcal disease developed in the Czech Republic in 1993. The investigation of meningococcal noncapsular antigens revealed that the new strain Neisseria meningitidis C:2a:P1.2 (P1.5) is the causative agent. This strain has never been found in the Czech Republic before, at least not since 1973 (Czech(More)
The Neisseria meningitidis FAM20 strain secretes two proteins of unknown function, FrpA and FrpC, which contain typical RTX domains found in cytotoxins from other gram-negative pathogens. To evaluate whether the Frp proteins could be involved in meningococcal virulence, 65 isolates of all serogroups were screened by PCR for the presence of both frp genes.(More)
