| detection of dextranase-producing gram-negative oral bacteria. | thirty-one strains of 23 gram-negative oral bacterial species were examined for dextran-degrading activity on agar plates containing blue dextran. one strain each of capnocytophaga ochracea, capnocytophaga sputigena, prevotella loescheii, prevotella melaninogenica and prevotella oralis had detectable dextranase activity. the culture supernatants of p. melaninogenica and p. oralis cells contained dextranases of multiple sizes, but those of the other three species had a single size of enzyme. a 56 ... | 1998 | 9872116 |
| chorioamnionitis with intact membranes caused by capnocytophaga sputigena. | we report a case of chorioamnionitis with intact membranes caused by capnocytophaga sputigena. the pregnant woman was hospitalised in preterm labor without fever, neither tenderness, just regular contractions. in spite of the tocolitic treatment the patient gave birth to a girl at 29 weeks' gestation, weighing 1220 g and transferred to intensive care. the newborn had clinical and biological signs of infections and was initially treated by ampicillin, cephalosporin and metronidazol. capnocytophag ... | 1999 | 10221619 |
| second-trimester abortion caused by capnocytophaga sputigena: case report. | intra-amniotic infection is often the cause of a second-trimester abortion. the bacterial species involved include bacteria with low pathogenicity like ureaplasma urealyticum and various mycoplasma species. in this case we describe an intra-amniotic infection caused by capnocytophaga sputigena, often found in the normal bacterial flora of the oral cavity, but not in the vagina. oral sex during pregnancy was the most probable source of the infection. the aborted fetus showed signs of pneumonia up ... | 1999 | 10458530 |
| microbiology of subgingival plaque from children with localized prepubertal periodontitis. | localized prepubertal periodontitis has been described as a host-defect mediated form of bacterially induced periodontitis, with an early onset and rapid progression around a few teeth in children prior to puberty. to further our understanding of the etiology of this disease, we have examined the microbiological components of subgingival dental plaque in 9 children with localized prepubertal periodontitis to determine if patterns of putative pathogens existed, and have compared these results wit ... | 1987 | 10870471 |
| characterization and cross-reactivity of rabbit antisera to plaque toxins. | the effects of heat labile, high molecular weight water-soluble toxins from bacterial plaque on hl60 promyelocytic cells were examined. on gel filtration, four inhibitors of hl60 cell growth and two inhibitors of hela cell growth (pt1, pt2) were detected. the first and third hl60 cell inhibitors corresponded to the two hela cell inhibitors. the last eluted hl60 cell inhibitor (plaque leukotoxin, pl) did not inhibit hela cell growth. anti-pt2 antibodies reduced the activity of enriched pt2 by 20- ... | 1987 | 10870474 |
| early microbial colonization of permucosal implants in edentulous patients. | in edentulous patients, the microbial colonization of permucosal implants of sintered hydroxyapatite was studied. samples were taken from mucosa and dentures before insertion of implants and from supra- and subgingival sites two to 10 weeks after insertion. in total, five patients and 10 implants with clinically healthy peri-implant tissues were studied. the samples were investigated by dark-field microscopy and anaerobic culture. the supragingival plaque of the implants was dominated by gram-po ... | 1987 | 10872401 |
| microbial composition of supra- and subgingival plaque in subjects with adult periodontitis. | the purpose of the present study was to compare and relate the microbial composition of supra and subgingival plaque in 23 adult periodontitis subjects (mean age 51 +/- 14 years). | 2000 | 11034118 |
| pcr detection of capnocytophaga species in dental plaque samples from children aged 2 to 12 years. | the purpose of this study was to detect the presence of capnocytophaga sputigena, c. ochracea, and c. gingivalis in plaque samples from the toothbrushes of 122 children, using a polymerase chain reaction (pcr) method. the subjects were 25, 85, and 12 children with healthy gingiva, gingivitis, and periodontitis, respectively, ranging in age from 2-12 years old. plaque samples were collected from all erupted tooth sites using a sterile toothbrush. the mean amount of dna recovered from the samples ... | 2001 | 11270602 |
| relationship of periodontopathic bacteria with early-onset periodontitis in down's syndrome. | down's syndrome (ds) patients often develop severe early-onset marginal periodontitis in early adulthood; however, there is little information available on the microbiology of ds periodontitis. | 2001 | 11327065 |
