25. Neipseria meningitedis no Brasil: implantação de novo método para diagnóstico molecular e caracterização genética por Multilocus Sequence Typing - MLST / Neipseria meningitedis in Brazil: implantation of new method for molecular diagnosis and genetic characterization for Multilocus Sequence Typing - MLST
In the last 10 years, meningococcal disease in Brazil, has presented endemic features and high lethality rates. In some states like Rio de Janeiro, recent data show a 100% increase in the lethality rate, with no changes in the number of cases. These high lethality rates and the occurrence of outbreaks throughout the country have led us to analyze isolates fr

26. Emergence of new clone of Neisseria meningitidis Serogroup C in Grande São Paulo, 1990 a 2003 / Descrição de um novo clone de Neisseria meningitidis Sorogrupo C, Grande São Paulo, 1990 a 2003
Neisseria meningitidis (Men) is an important cause of morbidity and mortality and is a leading cause of bacterial meningitis and septicemia in children and young adults in Brazil. Meningococcal disease caused by MenC started becoming the most prevalent serogroup in 2001, representing 62.7% of all MD cases serogrouped in 2003 in Greater Sao Paulo and approxim

27. Deficiency of the eighth component of complement associated with recurrent meningococcal meningitis: case report and literature review
The authors report a case of deficiency of the eighth component of complement in a young adult with a history of three episodes of meningitis; one of them proved to be meningococcal. The literature was reviewed and meningitis due to Neisseria meningitidis strains causing disease in complement-deficient and complement-sufficient patients was demonstrated. Men

28. Three decades of meningococcal disease in the State of Santa Catarina, Brazil
Consolidation of data on meningococcal disease surveillance for the state of Santa Catarina, Brazil, has provided new insight about the evolution of this disease during the period of 1971-2000. A descriptive epidemiological study, based on retrospective analysis of all cases of meningococcal disease notified in the state of Santa Catarina, linked the surveil

29. Effectiveness of a mass immunization campaign against serogroup C meningococci in children in the Federal State of Santa Catarina, Brazil
In addition to vaccine efficacy studies, there is a pressing need to evaluate vaccine effectiveness in a way that takes into account the limitations of health care systems in certain settings. An attempt to reach this objective was exemplified by a vaccination campaign against serogroup C meningococci in the federal state of Santa Catarina, in Brazil. A poly

30. Waldenström's Disease Complicated by Recurrent Meningococcal Arthritis
Meningococcal arthritis is rare. We report a patient in whom a first episode of meningococcal arthritis revealed Waldenström's disease and who experienced a second episode of meningococcal arthritis 8 years later. We suggest that an impaired immune response secondary to Waldenström's disease favored the recurrence of meningococcal arthritis.

31. PCR of peripheral blood for diagnosis of meningococcal disease.
Meningococcal disease is normally suspected on clinical grounds and is confirmed by isolation of Neisseria meningitidis bacteria from blood or cerebrospinal fluid or, more recently, by serology or PCR of cerebrospinal fluid. Achieving confirmation of a clinical diagnosis of meningococcal disease has become more difficult in the last few years. The pre-hospit

32. Bench-to-bedside review: Genetic influences on meningococcal disease
This review discusses the possible involvement of a variety of genetic polymorphisms on the course of meningococcal disease. It has been shown that several common genetic polymorphisms can either influence the susceptibility to meningococcal disease or can account for a higher mortality rate in patients. Gene polymorphisms concerning antibody receptors, lipo

33. Diversity in pathogenicity can cause outbreaks of meningococcal disease
Neisseria meningitidis, the meningococcus, is a major cause of bacterial meningitis and septicemia worldwide. Infection in most cases leads to asymptomatic carriage and only rarely to disease. Meningococcal disease often occurs in outbreaks, which are both sporadic and highly unpredictable. The occurrence of disease outbreaks in a host population in which th

34. Molecular epidemiology of an outbreak of meningococcal disease in a university community.
Over a 2-month period, five cases of serogroup C meningococcal disease occurred in Iowa City, Iowa. Two patients were unacquainted university students who had independently visited another university with endemic meningococcal disease. Isolates from these patients had DNA fingerprints identical to those of the isolates responsible for infections on the other

35. Confirmation of suspicious cases of meningococcal meningitis by PCR and enzyme-linked immunosorbent assay.
A significant problem in efficacy trials of meningococcal vaccines has been accurate identification of all cases of meningococcal disease that occur in study populations. The accuracy of case determination would be improved by utilizing methods which confirm or disprove suspicious cases of meningococcal disease that are culture negative. A collection of seru

36. Antibody response in group B meningococcal disease determined by enzyme-linked immunosorbent assay with serotype 15 outer membrane antigen.
To elucidate pathogenic aspects and serodiagnostic possibilities for meningococcal disease, we investigated levels of specific antimeningococcal immunoglobulin G (IgG), IgA, and IgM in serum by using an enzyme-linked immunosorbent assay with outer membrane antigen prepared from a Neisseria meningitidis B:15:P1.16 strain. Serum samples were drawn on hospital
