| antimicrobial susceptibility of bifidobacterium. | the susceptibility pattern of 459 strains of bifidobacteria, representing 15 species, to 16 antimicrobial agents was determined by the broth dilution method. the majority of the strains derived from human faeces. penicillin g, erythromycin, clindamycin, vancomycin and bacitracin were the most active compounds; they inhibited 90% of the strains at less than 1.6 micrograms/ml. all strains were susceptible to chloramphenicol (mic90 = 2.0-5.8 micrograms/ml) and also to lincomycin (mic50 = 0.64-1.5 m ... | 1983 | 6638754 |
| digoxigenin-labeled deoxyribonucleic acid probes for the enumeration of bifidobacteria in fecal samples. | the numbers of bifidobacteria in fecal samples were specifically determined by colony hybridization with the mixture of digoxigenin-labeled dna probes that were prepared from whole chromosomal dna of bifidobacterium longum 6001 and bifidobacterium adolescentis 6003. these dna probes strongly hybridized with dna of b. longum, b. adolescentis, bifidobacterium breve, bifidobacterium suis, bifidobacterium infantis, bifidobacterium bifidum, bifidobacterium angulatum, and bifidobacterium animalis. det ... | 1997 | 9241587 |
| autoaggregation and adhesion ability in a bifidobacterium suis strain. | on the basis of autoaggregation ability, two different phenotypes (agg+ and agg-) were selected from a strain (bsu895) of bifidobacterium suis. the relationship between autoaggregation and adhesion of bacteria to intestinal tissue was investigated by observing the adhesivity of the two phenotypic variants to ileum and colon tissue pieces collected from six new-born piglets. the results suggest that there is a good relationship between autoaggregation and adhesion as variant agg+ (autoaggregating ... | 1998 | 9830151 |
| molecular microbial analysis of bifidobacterium isolates from different environments by the species-specific amplified ribosomal dna restriction analysis (ardra). | one hundred and six isolates of the genus bifidobacterium, isolated from different environments (mainly gastrointestinal), were identified and classified taxonomically to species level by amplified ribosomal dna restriction analysis. two restriction endonucleases (sau3ai and bamhi) were chosen for aligning the 16s rrna sequences of 16 bifidobacterial species retrieved from various databases, to obtain species-specific restriction patterns. a rapid and accurate identification scheme was obtained ... | 2001 | 11451515 |
| new approach to phylogenetic analysis of the genus bifidobacterium based on partial hsp60 gene sequences. | the partial 60 kda heat-shock protein (hsp60) genes of 36 bifidobacterium strains representing 30 different bifidobacterium species and subspecies and of the type strain of gardnerella vaginalis were cloned and sequenced using a pair of universal degenerate hsp60 pcr primers. the hsp60 dna sequence similarities were determined for the taxa at various ranks as follows: 99.4-100% within the same species, 96% at the subspecies level, and 73-96% (mean 85%) at the interspecies level (and 98% in the c ... | 2001 | 11594590 |
| unification of bifidobacterium infantis and bifidobacterium suis as bifidobacterium longum. | the relationships between bifidobacterium infantis, bifidobacterium longum and bifidobacterium suis were examined by means of carbohydrate fermentation, dna-dna hybridization, ribotyping and random amplified polymorphic dna-pcr (rapd-pcr). the levels of dna-dna hybridization among the strains of b. infantis, b. longum and b. suis used in this study were 67-81% under optimal conditions (42 degrees c) and 63-85% under stringent conditions (52 degrees c). although the strains showed varied carbohyd ... | 2002 | 12508852 |
| proposal to reclassify the three biotypes of bifidobacterium longum as three subspecies: bifidobacterium longum subsp. longum subsp. nov., bifidobacterium longum subsp. infantis comb. nov. and bifidobacterium longum subsp. suis comb. nov. | in the year 2002, bifidobacterium longum, bifidobacterium infantis and bifidobacterium suis were unified into a single species, bifidobacterium longum, preserving the former species names through the creation of the three biotypes 'longum', 'infantis' and 'suis'. consequently, the use of the species names b. infantis and b. suis was to be discontinued. the above taxonomic rearrangement of b. longum was based on dna-dna hybridizations and 16s rrna and hsp60 gene sequence analysis. however, a vari ... | 2008 | 18398167 |
| detection of bifidobacterium animalis subsp. lactis (bb12) in the intestine after feeding of sows and their piglets. | a real-time pcr method has been developed to distinguish bifidobacterium animalis subspecies in the gastrointestinal tracts of pigs. identification of a highly conserved single-copy tuf gene encoding the elongation factor tu involved in bacterial protein biosynthesis was used as a marker to differentiate homologous bifidobacterium animalis subsp. lactis (strain bb12) from bifidobacterium animalis subsp. animalis, as well as bifidobacterium suis, bifidobacterium breve, bifidobacterium longum, sev ... | 2008 | 18689506 |
| fucosyllactose and l-fucose utilization of infant bifidobacterium longum and bifidobacterium kashiwanohense. | human milk oligosaccharides (hmos) are one of the major glycan source of the infant gut microbiota. the two species that predominate the infant bifidobacteria community, bifidobacterium longum subsp. infantis and bifidobacterium bifidum, possess an arsenal of enzymes including α-fucosidases, sialidases, and β-galactosidases to metabolise hmos. recently bifidobacteria were obtained from the stool of six month old kenyan infants including species such as bifidobacterium kashiwanohense, and bifidob ... | 2016 | 27782805 |
