Comparative genomic and phylogenetic analyses of gammaproteobacterial glg genes traced the origin of the Escherichia coli glycogen glgBXCAP operon to…

© 2015 Almagro et al. Production of branched α-glucan, glycogen-like polymers is widely spread in the Bacteria domain. The glycogen pathway of synthesis and degradation has been fairly well characterized in the model enterobacterial species Escherichia coli (order Enterobacteriales, class Gammaproteobacteria), in which the cognate genes (branching enzyme glgB, debranching enzyme glgX, ADP-glucose pyrophosphorylase glgC, glycogen synthase glgA, and glycogen phosphorylase glgP) are clustered in a glgBXCAP operon arrangement. However, the evolutionary origin of this particular arrangement and of its constituent genes is unknown. Here, by using 265 complete gammaproteobacterial genomes we have …

Effectiveness of hexavalent vaccines against invasive Haemophilus influenzae type b disease: Germany's experience after 5 years of licensure

2007

Summary Vaccine effectiveness (VE) was determined with a case-cohort approach using Cox regression. Cases with confirmed systemic Hib infections in children born from 1 August 2000 to 31 December 2004 were ascertained through two independent nationwide active surveillance systems. A representative cohort of 1303 children born in the same time frame was randomly sampled in a nationwide immunisation survey. Thirty cases were eligible for VE calculation; 19 were unvaccinated and 11 vaccinated with hexavalent vaccines. VE was 68.4% (95% CI: 19.0–87.6) for incomplete primary series and 90.4% (95% CI: 70.6–96.8) for the full primary series. For full immunisation VE was 100.0% (95% CI: 52.7–100.0)…

Serotypes of Aggregatibacter actinomycetemcomitans in relation to periodontal status and geographic origin of individuals-a review of the literature

2014

Objectives: Several studies have focused on the relationship among serotype distribution, ethnical status and geo - graphic populations, and periodontal conditions. Studies that have investigated the prevalence and the distribution of A. actinomycetemcomitans serotypes and the relation between the different serotypes of the bacterium and periodontal status were reviewed. Material and Methods: A systematic literature search for publications regarding the distribution of A. actinomyc - etemcomitans serotypes in subgingival samples of periodontitis patients and periodontally healthy subjects by employing polymerase chain reaction (PCR) was conducted. Results: From the 85 studies identified in …
