| reclassification of eubacterium formicigenerans holdeman and moore 1974 as dorea formicigenerans gen. nov., comb. nov., and description of dorea longicatena sp. nov., isolated from human faeces. | two strains of a gram-positively staining, obligately anaerobic, non-spore-forming, rod-shaped bacterium, designated strains 111-13a and 111-35t, were isolated from human faeces. analysis of the 16s rrna gene sequences indicated that these strains were members of the clostridium coccoides rrna group of organisms. the nearest relatives of the unknown bacterium were eubacterium formicigenerans (having a sequence similarity of 94%) and an uncultured bacterium (similarity > 99%). characterization st ... | 2002 | 11931151 |

| studies of fish consumption as source of methylmercury should consider fish-meal-fed farmed fish and other animal foods. | the co-occurrence of fish mehg and omega-3 fatty acids in wild species can indeed be optimized by choosing certain species. farmed finfish and shellfish that are fed fish-meal, however, can bioconcentrate both mehg (in muscle) and organohalogen pollutants passed on in the fat components [dorea, j.g., 2006. fish meal in animal feed and human exposure to persistent bioaccumulative and toxic substances. j. food prot. 69, 2777-2785); when fish-meal is used to feed farm animals it may offer the worst ... | 2009 | 19027108 |
| fermented liquid feed enhances bacterial diversity in piglet intestine. | because of limitations imposed on the antibiotic use in animal industry, there is a need for alternatives to maintain the efficiency of production. one of them may be the use of fermented liquid feed (flf) but how it affects gut ecology is poorly understood. we investigated the effect of three diets, standard dry feed (control), dry feed supplemented with antibiotics, and fermented liquid feed (flf, fermented with lactobacillus plantarum), on gut bacterial diversity in piglets. the structure of ... | 2010 | 19393756 |
| towards the human intestinal microbiota phylogenetic core. | the paradox of a host specificity of the human faecal microbiota otherwise acknowledged as characterized by global functionalities conserved between humans led us to explore the existence of a phylogenetic core. we investigated the presence of a set of bacterial molecular species that would be altogether dominant and prevalent within the faecal microbiota of healthy humans. a total of 10 456 non-chimeric bacterial 16s rrna sequences were obtained after cloning of pcr-amplified rdna from 17 human ... | 2009 | 19601958 |
| exposure of different bacterial inocula to newborn chicken affects gut microbiota development and ileum gene expression. | the transition from a sterile gut environment to the development of microbiota in the newborns is not fully understood. the objective of this study was to investigate the impact of exposure to bacterial communities on the development of gut microbiota in the newly hatched chicken. a total of 90 as-hatched chicks were divided into three groups. groups a and b were treated with inocula of the cecal origin, whereas group c was fed with sterile water. the major bacteria in inoculum-i to treat group ... | 2010 | 19956274 |
| production of an antibacterial substance in the digestive tract involved in colonization-resistance against clostridium perfringens. | ruminococcus gnavus e1, bacteroides thetaiotaomicron lemf4, clostridium hathewayi lemc7, and clostridium orbiscindens lemh9 were isolated from ex germ-free mice inoculated with a human faecal microbiota. when initially germ-free mice who were previously inoculated with the strain e1 alone, or a four-strain consortium [e1, lemf4, lemc7, and lemh9], were then challenged with 10⁸ counts of clostridium perfringens; the target strain was rapidly eliminated from the digestive tract of the animals (<10 ... | 2010 | 20603221 |
| molecular characterization of mucosal adherent bacteria and associations with colorectal adenomas. | the human large bowel is colonized by complex and diverse bacterial communities. however, the relationship between commensal bowel bacteria and adenomas (colorectal cancer precursors) is unclear. this study aimed to characterize adherent bacteria in normal colon and evaluate differences in community composition associated with colorectal adenomas. we evaluated adherent bacteria in normal colonic mucosa of 21 adenoma and 23 non-adenoma subjects enrolled in a cross sectional study. terminal restri ... | 2010 | 20740058 |
| exposure to a social stressor alters the structure of the intestinal microbiota: implications for stressor-induced immunomodulation. | the bodies of most animals are populated by highly complex and genetically diverse communities of microorganisms. the majority of these microbes reside within the intestines in largely stable but dynamically interactive climax communities that positively interact with their host. studies from this laboratory have shown that stressor exposure impacts the stability of the microbiota and leads to bacterial translocation. the biological importance of these alterations, however, is not well understoo ... | 2010 | 21040780 |
| global and deep molecular analysis of microbiota signatures in fecal samples from patients with irritable bowel syndrome. | background & aims:: irritable bowel syndrome (ibs) has been associated with disruptions to the intestinal microbiota, but studies have had limited power, coverage, and depth of analysis. we aimed to define microbial populations that can be used discriminate the fecal microbiota of patients with ibs from that of healthy subjects and correlate these with ibs intestinal symptom scores. methods:: the microbiota composition was assessed by global and deep molecular analysis of fecal samples from 62 p ... | 2011 | 21820992 |
| the currently used commercial dna-extraction methods give different results of clostridial and actinobacterial populations derived from human fecal samples. | recently several human health-related microbiota studies have had partly contradictory results. as some differences may be explained by methodologies applied, we evaluated how different storage conditions and commonly used dna-extraction kits affect bacterial composition, diversity, and numbers of human fecal microbiota. according to our results, the dna-extraction did not affect the diversity, composition, or quantity of bacteroides spp., whereas after a week's storage at -20 °c, the numbers of ... | 2011 | 22098067 |
