Molecular Epidemiology of Neisseria meningitidis Serogroup B in Brazil
BACKGROUND Neisseria meningitidis serogroup B has been predominant in Brazil, but no broadly effective vaccine is available to prevent endemic meningococcal disease. To understand genetic diversity among serogroup B strains in Brazil, we selected a nationally representative sample of clinical disease isolates from 2004, and a temporally representative sample for the state of São Paulo (1988-200...
متن کاملsimultaneous molecular detection of neisseria meningitidis and haemophilus influenzae
objective: bacterial meningitis is a dangerous and sometimes fatal infection that affects the central nervous system. because some antibiotics can prevent some types of these bacteria and supress them from spreading and infecting, therefore it is important to know what type of virus or bacterium is causing meningitis. haemophilus influenzae and neisseria meningitides are the two main pathogens...
متن کاملMolecular analysis of the serotyping antigens of Neisseria meningitidis.
Molecular approaches to the rapid analysis of the serotyping antigens of Neisseria meningitidis, the class 2 and 3 outer membrane proteins (OMPs), were developed, evaluated, and used to study 12 antigenic variants of these proteins. A primer set for the polymerase chain reaction (PCR) amplification of the genes encoding these antigens was devised. Low-stringency amplification of meningococcal c...
متن کاملMolecular polymorphism and epidemiology of Neisseria meningitidis immunoglobulin A1 proteases.
Neisseria meningitidis is one of several important bacterial pathogens that secrete a specific protease capable of cleaving human immunoglobulin A1 (IgA1) in the hinge region. To obtain further information on this putative virulence factor, we examined the IgA1 protease and iga gene region of 133 isolates of N. meningitidis assigned to 88 multilocus enzyme genotypes and representing major epide...
متن کاملNeisseria meningitidis W135, Turkey
We describe the first case of Neisseria meningitidis W135 meningitis in Turkey. The strain was genotypically unrelated to the clone (W)ET-37, isolated from Hajj pilgrims in 2000.
