| detection of a fibroblast proliferation inhibitory factor from capnocytophaga sputigena. | the addition of a sonic extract of capnocytophaga sputigena to the culture fluid to human fibroblasts resulted in an inhibition of cell proliferation. the inhibition was dose-related (200 micrograms/ml caused a 90% inhibition, and 1,000 micrograms/ml caused a complete cessation of growth). the growth inhibition was not due to alterations in culture medium, ph or ionic strength, or to the effects of the c. sputigena lipopolysaccharide. | 1980 | 7358430 |

| isolation of capnocytophaga species from non-vital anterior teeth. | root-canal infection is very common in india. both aerobic and anaerobic organisms have been claimed for its aetiology. however, isolation of capnocytophaga species from non-vital anterior teeth is sparse. in this study a solitary case of capnocytophagal root canal infection is reported. | 1993 | 8354551 |
| capnocytophaga sputigena bacteremia associated with acute leukemia. | during a three-year period, capnocytophaga sputigena bacteremia occurred in three patients with acute leukemia receiving induction therapy on a hematology ward. oral pathology such as periodontitis or severe mucositis was considered to be the most likely source of bacteremia. all three blood culture isolates were identified as that species by deoxyribonucleic acid (dna) homology studies. because of the phenotypical similarity of capnocytophaga species, it is difficult to differentiate them by co ... | 1993 | 8360517 |

| in vitro antimicrobial activity of the human neutrophil cytosolic s-100 protein complex, calprotectin, against capnocytophaga sputigena. | calprotectin is a complex of two anionic proteins found in abundance in the cytosol of neutrophils, certain macrophages, and oral epithelial keratinocytes. bacteria of the genus capnocytophaga are pathogens of periodontal origin which can cause systemic infection in neutropenic subjects. recently, it has been observed that capnocytophaga may be internalized by neutrophils within the cytosol rather than within a membrane-delimited phagosome. the purpose of this study was to test the in vitro anti ... | 1993 | 8423249 |
| sub-gingival microflora in macaca mulatta species of rhesus monkey. | the macaca mulatta species of rhesus monkey is one of several non-human primate (nhp) models for periodontal disease. this report presents the bacteriology of the gingival sulci in m. mulatta monkeys. three sub-gingival sites (maxillary right central incisor, the disto-buccal of the mandibular left second molar and mesio-buccal of the mandibular right second molar) of 9 monkeys were evaluated clinically before scaling and 7 days after scaling. plaque samples were obtained from sub-gingival sites ... | 1993 | 8426283 |

| susceptibility of capnocytophaga to antimicrobial agents. | a total of 22 clinically isolated capnocytophaga strains were tested for their susceptibility to antimicrobial agents frequently used in dental practice. all strains were susceptible to penicillin, ampicillin, cefaclor, cefuroxime, erythromycin, clindamycin and tetracycline. metronidazole had poor activity against most strains. | 1995 | 8596122 |
| in vivo cleavage of immunoglobulin a1 by immunoglobulin a1 proteases from prevotella and capnocytophaga species. | immunoglobulin a1 (iga1) proteases secreted by oral prevotella and capnocytophaga species specifically cleave iga1 at the same peptide bond in the hinge region, leaving intact monomeric fab and fc fragments. assuming that prevotella- and capnocytophaga-induced fab fragments of iga1 expose a specific immunogenic neoepitope at the cleavage site, we established an enzyme-linked immunosorbent assay to measure human serum antibodies to this neoepitope as indirect evidence of in vivo activity of prevo ... | 1995 | 8596672 |
| porphyromonas gingivalis outer membrane vesicles promote bacterial resistance to chlorhexidine. | porphyromonas gingivalis has been frequently associated with some types of periodontal diseases and possesses various mechanisms favoring the pathogenic process. it has been recently observed that vesicles elaborated by p. gingivalis are able to protect bacteria from the bactericidal activity of human serum. the aim of the present investigation was to evaluate the ability of vesicles from p. gingivalis in protecting oral bacteria against chlorhexidine. data indicate that vesicles released by p. ... | 1995 | 8596676 |
