In columns 10-17 and in lanes F to J of columns 1-9 PCR products from LY2109761 nmr patient samples of the different diseased
MK-4827 supplier groups and the periodontitis resistant (PR) group were applied. (a): Signals in all fields prove successful PCR-amplification. (b): Absence of signals in all bacterial controls along with strong signal in field A1 proves specificity Amoxicillin of the experiments. Prevalences of F. alocis in all diseased collectives exceed the prevalence in the PR group. Statistical analysis Statistical evaluation of the dot blot hybridization results was performed using the exact chi-square test. The prevalence of F. alocis in different patient groups was compared. Moreover, the presence of F. alocis in relation to the PPD was analysed. P values below 0.05 were considered statistically significant. Clinical samples for FISH A carrier system designed to collect biofilms grown in vivo in periodontal pockets was used for sampling [31]. Ethics approval for subgingival sample collection was given by the Ethical Committee at Charité – Universitätsmedizin Berlin. Expanded polytetrafluoroethylene (ePTFE) membranes were placed in periodontal pockets of GAP patients for 7 to 14 days and colonized by the subgingival bacterial flora.
