| comparison of compositions and metabolic activities of fecal microbiotas in young adults and in antibiotic-treated and non-antibiotic-treated elderly subjects. | the colonic microbiota mediates many cellular and molecular events in the host that are important to health. these processes can be affected in the elderly, because in some individuals, the composition and metabolic activities of the microbiota change with age. detailed characterizations of the major groups of fecal bacteria in healthy young adults, in healthy elderly people, and in hospitalized elderly patients receiving antibiotics were made in this study, together with measurements of their m ... | 2004 | 15466557 |
| isolation, growth on prebiotics and probiotic potential of novel bifidobacteria from pigs. | bifidobacteria were isolated from the faeces of pigs of various ages and examined for their potential use as probiotics in combination with di- and oligosaccharides. ninty-six per cent of the isolates were found to have characteristics in common with bifidobacterium boum, b. thermophilum and b. choerinum. b. thermophilum was most commonly isolated from sows, whereas most of the other strains were isolated from piglets. a few strains of each species were able to grow in the presence of air. a mic ... | 2004 | 16701498 |
| species identification of genus bifidobacterium based on partial hsp60 gene sequences and proposal of bifidobacterium thermacidophilum subsp. porcinum subsp. nov. | sequence homology of partial 60 kda heat-shock protein (hsp60) genes was analysed for 50 bifidobacterium strains that represent 12 bifidobacterium species and subspecies with validly published names. sequence similarities were 96.5-100 % within the same species, 95.5-97 % at the subspecies level and 80-96 % (mean, 88 %) at the interspecies level among the 10 bifidobacterium species. hence, the hsp60 gene was a more accurate tool for species identification within the genus bifidobacterium than 16 ... | 2003 | 13130059 |
| pseudoscardovia suis gen. nov., sp. nov., a new member of the family bifidobacteriaceae isolated from the digestive tract of wild pigs (sus scrofa). | seventeen fructose-6-phosphate phosphoketolase-positive bacterial strains were isolated from the digestive tract of wild pigs (sus scrofa). most of them were identified as bifidobacterium boum according to sequences of 16s rrna gene. two strains isolated from the small intestine content had unusual morphology of cells in comparison with bifidobacteria. cells growing in liquid anaerobic media were regular shaped rods arranged mostly in pairs. these isolates showed relatively low 16s rrna gene seq ... | 2013 | 23122702 |
| anti-inflammatory and intestinal barrier-protective activities of commensal lactobacilli and bifidobacteria in thoroughbreds: role of probiotics in diarrhea prevention in neonatal thoroughbreds. | we previously isolated the commensal bacteria lactobacilli and bifidobacteria from the thoroughbred intestine and prepared the horse probiotics lacfi(tm), consisting of lactobacillus ruminis kk14, l. equi kk 15, l. reuteri kk18, l. johnsonii kk21, and bifidobacterium boum hu. here, we found that the five lacfi(tm) constituent strains remarkably suppressed pro-inflammatory interleukin-17 production in mouse splenocytes stimulated with interleukin-6 and transforming growth factor-β. the protective ... | 2014 | 25013357 |
