Molecular Characteristics and Epidemiology of Meningococcal Carriage, Burkina Faso, 2003
To describe Neisseria meningitidis strains in the African meningitis belt in 2003, we obtained 2,389 oropharyngeal swabs at 5 monthly visits a representative population sample (age range 4-29 years) in Bobo-Dioulasso, Burkina Faso. A total of 152 carriage isolates were grouped, serotyped, and genotyped. Most isolates were NG:NT:NST sequence type (ST) 192 (63% of all N. meningitidis), followed b...
متن کاملGenetic diversity and carriage dynamics of Neisseria lactamica in infants.
Neisseria lactamica, a harmless human commensal found predominantly in the upper respiratory tracts of infants, is closely related to Neisseria meningitidis, a pathogen of global significance. Colonization with N. lactamica may be responsible for the increase in immunity to meningococcal disease that occurs during childhood, when rates of meningococcal carriage are low. This observation has led...
متن کاملFirst molecular epidemiology study of Mycobacterium tuberculosis in Burkina Faso.
We conducted a molecular epidemiology study on 120 Mycobacterium tuberculosis isolates from patients presenting pulmonary tuberculosis (TB) in Burkina Faso. Classical antibiogram studies and genetic characterization, using mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-VNTR) typing and spoligotyping, were applied after culture. Molecular analysis of specific sign...
متن کاملNeisseria meningitidis serogroups A and W-135: carriage and immunity in Burkina Faso, 2003.
OBJECTIVES We sought to describe Neisseria meningitidis immunity and its association with pharyngeal carriage in Burkina Faso, where N. meningitidis serogroup W-135 and serogroup A disease are hyperendemic and most of the population received polysaccharide A/C vaccine during 2002. METHODS We collected oropharyngeal swab samples from healthy residents of Bobo-Dioulasso (4-14 years old, n=238; ...
متن کاملNeisseria meningitidis Serogroup W, Burkina Faso, 2012
In 2010, Burkina Faso became the first country to introduce meningococcal serogroup A conjugate vaccine (PsA-TT). During 2012, Burkina Faso reported increases in Neisseria meningitidis serogroup W, raising questions about whether these cases were a natural increase in disease or resulted from serogroup replacement after PsA-TT introduction. We analyzed national surveillance data to describe the...
