| species composition of bacteroidales order bacteria in the feces of healthy people of various ages. | a study of species distribution of numerically predominant bacteroidales order isolates in feces of healthy people aged 1-33 years was accomplished using a combination of amplified ribosomal dna restriction analysis (ardra) and 16s ribosomal dna (rdna) sequencing. it was found that the majority of isolates in all age groups belonged to species b. xylanisolvens, b. vulgatus, and b. uniformis. members of genera alistipes, parabacteroides, odoribacter, barnesiella, and prevotella were also detected ... | 2012 | 22232251 |
| usefulness of the hsp60 gene for the identification and classification of gram-negative anaerobic rods. | the hsp60 gene sequences were determined for 121 strains of gram-negative anaerobic rods, including the genera bacteroides, barnesiella, butyricimonas, odoribacter, parabacteroides, paraprevotella, porphyromonas, prevotella and tannerella. the mean pairwise hsp60 gene sequence similarity (73.8-97.1 %) between species in each genus, except for the genus tannerella that comprises one species, was significantly less than that of the 16s rrna gene sequence (88.3-96.3 %). only pairwise hsp60 gene seq ... | 2010 | 20671088 |
| butyricimonas synergistica gen. nov., sp. nov. and butyricimonas virosa sp. nov., butyric acid-producing bacteria in the family 'porphyromonadaceae' isolated from rat faeces. | two bacterial strains, designated mt01(t) and mt12(t), isolated from rat faeces were characterized by using a polyphasic taxonomic approach that included analysis of their phenotypic and biochemical features, cellular fatty acid profiles, menaquinone profiles and phylogeny based on 16s rrna gene sequences. the 16s rrna gene sequence analysis showed that these strains were members of the family 'porphyromonadaceae'. the strains shared 94 % 16s rrna gene sequence similarity with each other and wer ... | 2009 | 19542124 |
| dialister succinatiphilus sp. nov. and barnesiella intestinihominis sp. nov., isolated from human faeces. | two anaerobic, non-spore-forming, bacteria (yit 11850(t) and yit 11860(t)) that stained gram-negative, were isolated from human faeces. cells of strain yit 11850(t) were coccobacilli, asaccharolytic and largely unreactive, with only traces of lactate and propionate as metabolic end products; however, strain yit 11850(t) was able to decarboxylate succinate to propionate. the dna g+c content of strain yit 11850(t) was 51.9 mol%. following 16s rrna gene sequence analysis, this strain was found to b ... | 2008 | 19060046 |
| application of several molecular techniques to study numerically predominant bifidobacterium spp. and bacteroidales order strains in the feces of healthy children. | bifidobacteria and bacteroides-like bacteria are strictly anaerobic nonpathogenic members of human intestinal microflora. here we describe an analysis of the species and subspecies composition of these bacterial populations in healthy children using a combination of culture and molecular methods at two different time points. it was found that b. bifidum and b. longum are the most common dominant taxons in infants aged between 8 and 16 months. the majority of the infants carried several dominant ... | 2008 | 18323636 |
| barnesiella viscericola gen. nov., sp. nov., a novel member of the family porphyromonadaceae isolated from chicken caecum. | two bacterial strains isolated from chicken caecum, c46t and c47, were characterized using a polyphasic taxonomic approach that included analysis of the phenotypic and biochemical features, cellular fatty acid profiles, menaquinone profiles and phylogenetic position (using 16s rrna gene sequence analysis). the 16s rrna gene sequence analysis showed that these strains belonged to the family porphyromonadaceae. these strains shared 100 % 16s rrna gene sequence similarity with each other and were r ... | 2007 | 17267976 |
