Genetic relationships and clonal population structure of serotype 2 strains of Neisseria meningitidis

Genetic relationships among serogroup B: serotype 4 Neisseria meningitidis strains.

We compared the results obtained by serotyping of PorB epitopes using an expanded panel of monoclonal antibodies (mAb) including mAb 7 and mAb 10, with results obtained by RFLP of rRNA genes (ribotyping). The purpose of this study was to assess the correlation between phenotypic- and genotypic- methods for typing N. meningitidis. The ribotypes obtained using ClaI or EcoRV endonucleases grouped ...

Neisseria meningitidis serotype W135.

Genetic heterogeneity of strains of Neisseria meningitidis belonging to serotype 22 isolated in the Czech Republic.

Strains of Neisseria meningitidis of serogroup B isolated in the Czech Republic frequently belong to serotype 22. We analyzed the genetic relationships among strains of this serotype by using the multilocus enzyme electrophoresis technique and the polymorphism of the pilA gene. Our results indicate that these strains correspond to a highly heterogeneous population rather than to the expansion o...

Neisseria Meningitidis Peritonitis Serotype C: Case Report

The greater part of foreign bodies (80%) pass through the gastrointestinal tract without difficulties, but 20% can obstruct the lumen, requiring endoscopic or surgical removal (1% of cases). As the esophagus is a narrow portion of the gastrointestinal tract, 28-68% objects are found in this region5. The symptoms depend on the location. Dysphagia, odynophagia and salivation suggest esophageal fo...

Clonal Groupings in Serogroup X Neisseria meningitidis

The genetic diversity of 134 serogroup X Neisseria meningitis isolates from Africa, Europe, and North America was analyzed by multilocus sequence typing and pulsed-field gel electrophoresis. Although most European and American isolates were highly diverse, one clonal grouping was identified in sporadic disease and carrier strains isolated over the last 2 decades in the United Kingdom, the Nethe...
