| denitrobacterium detoxificans gen. nov., sp. nov., a ruminal bacterium that respires on nitrocompounds. | a new group of anaerobic, gram-positive, high g + c (56-60 mol%) bacteria was isolated from the bovine rumen. of four strains characterized, all were non-motile and none produced spores. the isolates did not produce indole or h2s and did not hydrolyse gelatin. cells of each strain exhibited similar rod-shaped morphology (0.5-1.0 x 1.0-1.5 microns) although bulbous ends were sometimes present. none of the four strains were able to grow via oxidation of a variety of potentially fermentable substra ... | 2000 | 10758869 |
| quantification of mucosa-adhered microbiota of lambs and calves by the use of culture methods and fluorescent in situ hybridization coupled with flow cytometry techniques. | the intestinal mucosa-associated microbiota could play important biological roles due to its close proximity with the animal host, but knowledge on its composition is still limited. the aim of this study was to characterize the microbial communities tightly associated with different parts (rumen, duodenum and colon) of the gastrointestinal tract (git) of healthy lambs and calves by using both cultural, and fluorescent in situ hybridization-flow cytometry (fcm-fish) techniques. lactic acid bacter ... | 2007 | 17218070 |
| a comparative in vitro investigation into the effects of cooked meats on the human faecal microbiota. | protein fermentation is one of the important microbial activities in the human colon. meat foods rich in protein provide substantial resource for this metabolic activity. however, little information exists on the relative impact of different meats on the composition and activities of the human gut microbiota. similarly, little information is available on the confounding effects of cooking on these activities. in this study, beef, chicken and fish (salmon) were examined in vitro for their impact ... | 2010 | 20934523 |
| microbial and immunological responses relative to high-altitude exposure in mountaineers. | high-altitude exposure is often associated with gastrointestinal disorders, inflammation, and an increased risk of infection. we suspected microbial and immunological responses to high-altitude exposure in mountaineers resulting from changes in the balance of the intestinal microflora. | 2005 | 16118577 |
| characterization of novel human oral isolates and cloned 16s rdna sequences that fall in the family coriobacteriaceae: description of olsenella gen. nov., reclassification of lactobacillus uli as olsenella uli comb. nov. and description of olsenella profusa sp. nov. | the diversity of organisms present in the subgingival pockets of patients with periodontitis and acute necrotizing ulcerative gingivitis (anug) were examined previously. the 16s rrna genes of subgingival plaque bacteria were amplified using pcr with a universal forward primer and a spirochaete-selective reverse primer. the amplified dna was cloned into escherichia coli. in one subject with anug, 70 clones were sequenced. seventy-five per cent of the clones were spirochaetal, as expected. twelve ... | 2001 | 11594611 |
| development of 16s rrna-based probes for the coriobacterium group and the atopobium cluster and their application for enumeration of coriobacteriaceae in human feces from volunteers of different age groups. | two 16s rrna-targeted probes were developed: one for the coriobacterium group and the other for the atopobium cluster (which comprises most of the coriobacteriaceae species, including the coriobacterium group). the new probes were based on sequences of three new coriobacteriaceae strains isolated from human feces and clinical material and sequences from databases. application of the probes to fecal samples showed that formula-fed infants had higher numbers of coriobacterium group cells in their ... | 2000 | 11010909 |
| phylogenetic evidence for the transfer of eubacterium lentum to the genus eggerthella as eggerthella lenta gen. nov., comb. nov. | eubacterium lentum has unique phenotypic characters within the genus eubacterium. the 16s rrna sequence of eubacterium lentum was determined and its phylogenetic position was defined. this micro-organism is a member of the genus eubacterium but it is not closely related to eubacterium limosum, the type species of the genus eubacterium, and is nearer to collinsella aerofaciens and coriobacterium glomerans. a pcr-based identification system using species-specific primers designed on the basis of d ... | 1999 | 10555354 |
| phylogenetic and phenotypic evidence for the transfer of eubacterium aerofaciens to the genus collinsella as collinsella aerofaciens gen. nov., comb. nov. | three strains of eubacterium aerofacien, jcm 10188t, jcm 7790 and jcm 7791, and 178 freshly isolated strains of the eubacterium aerofaciens group from human faeces were characterized by biochemical tests, cell wall peptidoglycan type and 16s rrna analysis. the eubacterium aerofaciens group was divided into four groups by fermentation patterns of sucrose and cellobiose, and were further divided into 16 sub-groups by fermentation patterns of aesculin, salicin and amygdalin. all of the strains of t ... | 1999 | 10319476 |
| localization and transmission route of coriobacterium glomerans, the endosymbiont of pyrrhocorid bugs. | endosymbiotic gut bacteria play an essential role in the nutrition of many insects. most of the nutritional interactions investigated so far involve gammaproteobacterial symbionts, whereas other groups have received comparatively little attention. here, we report on the localization and the transmission route of the specific actinobacterial symbiont coriobacterium glomerans from the gut of the red firebug, pyrrhocoris apterus (hemiptera: pyrrhocoridae). the symbionts were detected by diagnostic ... | 2009 | 19583787 |
