| bulleidia extructa gen. nov., sp. nov., isolated from the oral cavity. | five strains of anaerobic non-sporing gram-positive bacilli isolated from advanced periodontitis (four strains) and a dentoalveolar abscess (one strain) that did not correspond to existing species were subjected to phenotypic and genetic characterization. following 16s rdna sequence analysis, they were found to constitute a novel branch of the low g+c gram-positive division of the phylogenetic tree related to erysipelothrix rhusiopathiae and holdemania filiformis. a new genus bulleidia, and the ... | 2000 | 10843035 |
| characterisation of eubacterium-like strains isolated from oral infections. | the genus eubacterium currently includes a heterogeneous group of gram-positive, non-spore-forming anaerobic bacilli, many of which are slow growing, fastidious and generally unreactive in biochemical tests. as a consequence, cultivation and identification of isolates are difficult and the taxonomy of the group remains indifferent. in this study, 105 isolates from odontogenic infections, infections associated with dental implants or saliva from healthy subjects and provisionally assigned to the ... | 2001 | 11699590 |
| gram-positive anaerobic bacilli in human periodontal disease. | the uncertain taxonomy of oral anaerobic gram-positive bacilli and their generally slow growing nature has limited the understanding of their role in periodontal disease. the current objective was to design and use species-specific oligonucleotide probes to investigate the relationship of selected gram-positive anaerobic bacilli to periodontal disease. | 2004 | 15206913 |
| bacterial diversity in necrotizing ulcerative periodontitis in hiv-positive subjects. | necrotizing ulcerative periodontitis (nup) is a painful and potentially debilitating affliction that affects about 2% to 6% of hiv-positive subjects. nup may be caused by specific microorganisms that are presently unknown or by microbial species not usually thought to cause periodontal infections. the purpose of this study was to define the bacterial species associated with nup in hiv-positive patients. | 2002 | 16013212 |
| the microbiology of the acute dental abscess. | the acute dental abscess is frequently underestimated in terms of its morbidity and mortality. the risk of potential serious consequences arising from the spread of a dental abscess is still relevant today with many hospital admissions for dental sepsis. the acute dental abscess is usually polymicrobial comprising facultative anaerobes, such as viridans group streptococci and the streptococcus anginosus group, with predominantly strict anaerobes, such as anaerobic cocci, prevotella and fusobacte ... | 2009 | 19141730 |
| polymerase chain reaction-denaturing gradient gel electrophoresis, cloning, and sequence analysis of bacteria associated with acute periapical abscesses in children. | polymerase chain reaction-denaturing gradient gel electrophoresis (pcr-dgge), cloning, and sequencing were applied to the microbiologic study of acute periapical abscesses of endodontic origin in children to examine the predominant bacteria. | 2010 | 20113778 |
