phylogenetic analysis of fusobacterium alocis and fusobacterium sulci based on 16s rrna gene sequences: proposal of filifactor alocis (cato, moore and moore) comb. nov. and eubacterium sulci (cato, moore and moore) comb. nov. | genes encoding the 16s rrna of fusobacterium alocis atcc 35896t and fusobacterium sulci atcc 35585t were sequenced. these sequences did not have any affinity with the 16s rrna gene sequences of members of the genus fusobacterium. fusobacterium alocis atcc 35896t and fusobacterium sulci atcc 35585t belonged to clostridium cluster xi; the species most closely related to these strains were filifactor villosus nctc 11220t and eubacterium infirmum w1471, respectively. two new combinations are propose ... | 1999 | 10555315 |
exploring salivary microbiota in aids patients with different periodontal statuses using 454 gs-flx titanium pyrosequencing. | patients with acquired immunodeficiency syndrome (aids) are at high risk of opportunistic infections. oral manifestations have been associated with the level of immunosuppression, these include periodontal diseases, and understanding the microbial populations in the oral cavity is crucial for clinical management. the aim of this study was to examine the salivary bacterial diversity in patients newly admitted to the aids ward of the public health clinical center (china). saliva samples were colle ... | 2015 | 26191508 |
microorganisms in root canal-treated teeth from a german population. | posttreatment apical periodontitis is usually associated with persistent or secondary intraradicular infection. this study evaluated the presence and relative levels of 28 bacterial taxa in treated root canals of teeth with posttreatment apical periodontitis from german patients using 16s ribosomal rna (rrna) gene probes in a reverse-capture checkerboard hybridization assay. species-specific polymerase chain reaction (pcr) was also performed to detect enterococcus faecalis and candida albicans. ... | 2008 | 18634922 |
molecular characterization of the presence of eubacterium spp and streptococcus spp in endodontic infections. | eubacterium spp. and streptococcus spp. are virulent, commonly identified microorganisms in endodontic infections. the purpose of this study was to use molecular methods to identify these organisms in 22 infected root canals that include eight cases with preoperative clinical symptoms and five cases with a history of diabetes mellitus. the presence of streptococcus spp. and eubacterium spp. was examined using two sets of pcr primers specific with multiple species within the respective genera. po ... | 2003 | 12823801 |
phylogeny of oral asaccharolytic eubacterium species determined by 16s ribosomal dna sequence comparison and proposal of eubacterium infirmum sp. nov. and eubacterium tardum sp. nov. | 16s rrna gene sequences of eubacterium brachy, eubacterium nodatum, eubacterium saphenum, eubacterium timidum, and two previously unnamed taxa were determined. the results of a phylogenetic analysis indicated that all of the strains sequenced belonged to a deep branch of the low-g+c-content gram-positive group. the levels of 16s ribosomal dna sequence similarity between species were low, suggesting that a number of genera may be represented in this group. the representatives of the two unnamed t ... | 1996 | 8863423 |
diversity of oral asaccharolytic eubacterium species in periodontitis--identification of novel phylotypes representing uncultivated taxa. | oral asaccharolytic eubacterium species are associated with periodontal disease and other oral infections. the aim of this study was to use a culture-independent molecular technique to determine the diversity of asaccharolytic eubacterium species in subgingival plaque in periodontitis. an oligonucleotide pcr primer designed to amplify 16s rrna genes of the oral asaccharolytic eubacterium branch of the phylogenetic tree was constructed. this primer was used together with a universal primer in pcr ... | 1999 | 10204481 |
