Genetics of capsule O-acetylation in serogroup C, W-135 and Y meningococci (2004)

Capsular polysaccharides of serogroup C, W-135 and Y meningococci were previously reported to be O-acetylated at the sialic acid residues. There is evidence that O-acetylation affects the...

Genetic Diversity of Neisseria lactamica Strains from Epidemiologically Defined Carriers
Alber, Dirk, Oberkötter, Mark, Suerbaum, Sebastian, Claus, Heike, Frosch, Matthias, Vogel, Ulrich
We assessed the genetic diversity of 26 Neisseria lactamica strains from epidemiologically related sources, i.e., groups of kindergartens and primary schools in three Bavarian towns, by the partial...

Using representational difference analysis, we isolated novel meningococcal restriction-modification (R-M) systems. NmeBI, which is a homologue of the R-M system HgaI of Pasteurella volantium, was...

α-2,3-Sialyltransferase mutants of three genetically and phenotypically diverse Neisseria meningitidis strains were compared with regard to resistance to human serum and systemic spread in the...

Serogroup C strains of Neisseria meningitidis were isolated from a Germany patient with severe meningococcal disease after a trip to the Czech Republic. These strains (case isolates) were...

Most cases of serogroup C meningococcal disease are caused by the clonal lineages ST-8 and ST-11. The gene encoding the putative restriction-modification system NmeDI is specific to these lineages....

The spa gene of Staphylococcus aureus encodes protein A and is used for typing of methicillin-resistant Staphylococcus aureus (MRSA). We used sequence typing of the spa gene repeat region to study...

We recently described the capsule null locus (cnl) of constitutively unencapsulated Neisseria meningitidis clonal lineages. cnl meningococci were recovered from healthy carriers at high frequency. We...

Nosocomial transmission of Neisseria meningitidis has only rarely been reported. Here, we present a significant spatiotemporal association of two cases of invasive meningococcal disease identified by...
Molecular Epidemiology of Hospital-Acquired Vancomycin-Resistant Enterococci▿
Abele-Horn, Marianne, Vogel, Ulrich, Klare, Ingo, Konstabel, Carola, Trabold, Rene, Kurihara, Risa, ...
Vancomycin-resistant Enterococcus faecium strains are a significant cause of nosocomial infections in predisposed patients. Multiple-locus variable-number tandem repeat analysis (MLVA) has been...

Antigen sequence typing (ST) of FetA is part of the molecular typing scheme of Neisseria meningitidis. Among invasive meningococcal isolates from 2,201 patients in Germany, we identified 11 strains...
