To compensate for the lack of laboratories in remote areas, the national reference laboratory for meningitis in Niger used polymerase chain reaction (PCR) to enhance the surveillance of meningitis caused by Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae. PCR effectively documented the wide geographic spread of N. meningitidis(More)
We studied polymorphism of penA (which encodes penicillin-binding protein 2) in 13 strains of Neisseria meningitidis susceptible to penicillin (pen(S)) and 12 strains with reduced susceptibility to penicillin (pen(I)). These strains differed in geographical origin. Serological and genetic typing showed that they were highly diverse and belonged to several(More)
The Global Meningococcal Initiative (GMI) is an international group of scientists and clinicians with recognized expertise in meningococcal disease including microbiology, immunology, epidemiology, public health and vaccinology. The GMI was established to promote the global prevention of meningococcal disease through education, research and international(More)
cases of W135 invasive meningococcal infection were reported in France. Of these, eight were linked to a recent travel history to Sub-Saharan Africa. These cases were reported in France concomitantly with the meningitis epidemic season in Sub-Saharan Africa. Considering the high number of travellers between France and West-African countries belonging to the(More)
The control of the expression of the pilin gene (pilE) in Neisseria gonorrhoeae under a wide variety of growth conditions has been studied. The expression of pilE was measured using transcriptional fusions between pilE and the gene encoding chloramphenicol acetyltransferase (CAT), and the level of pilin production was measured by Western blot analysis.
