Rhizobia described so far belong to three distinct phylogenetic branches within the alpha-2 subclass of Proteobacteria. Here we report the discovery of a fourth rhizobial branch involving bacteria of the Methylobacterium genus. Rhizobia isolated from Crotalaria legumes were assigned to a new species, "Methylobacterium nodulans," within the Methylobacterium(More)
A group of Eubacterium-like strains (designated group S14), isolated from the feces of healthy people, was characterized by biochemical tests, fatty acid analysis, cell wall murein analysis, and 16S rDNA analysis. Our results indicate that group S14 is phylogenetically a member of the Clostridium subphylum of the gram-positive bacteria. Despite a phenotypic(More)
Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease confirmed at postmortem. Those at highest risk are professional athletes who participate in contact sports and military personnel who are exposed to repetitive blast events. All neuropathologically confirmed CTE cases, to date, have had a history of repetitive head impacts. This suggests(More)
Rhizobial isolates that were obtained from both surface and deep soil samples in the Sahelian and Sudano-Guinean areas of Senegal (West Africa) under Acacia albida trees were compared with representative strains of known rhizobial species and genera. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of proteins was used to determine the(More)
The nucleotide sequence of the 16S rRNA gene of the type strain of Dialister pneumosintes was determined. Phylogenetic analysis revealed that this species belongs to the Sporomusa branch of the Clostridium subphylum of the gram-positive bacteria and should therefore be excluded from the family Bacteroidaceae. Within this branch, which encompasses several(More)
Intra-and Intergeneric Relationships of the Genus Aquaspirillum: Prolinoborus, a New Genus for Aquaspirillum fasciculus, with the Species Prolinoborus fasciculus comb. nov. A comprehensive study of the intra-and intergeneric relationships of AquaspiriUum species in which we used DNA-rRNA hybridization is described. Radioactively labeled rRNAs from(More)
Dyslexia is characterized by a deficit in language processing which mainly affects word decoding and spelling skills. In addition, children with dyslexia also show problems in mathematics. However, for the latter, the underlying structural correlates have not been investigated. Sixteen children with dyslexia (mean age 9.8 years [0.39]) and 24 typically(More)
The 16S rRNA gene sequence of the type strain of Ruminococcus flavefaciens, the type species of the genus Ruminococcus, was determined by PCR direct sequencing. A comparative sequence analysis showed that R. flavefaciens is phylogenetically related to a small cluster (cluster IV of Collins et al. [M. D. Collins, P. A. Lawson, A. Willems, J. J. Cordoba, J.(More)
