Enoxolone is a major component of a traditional plant called Licorice. This substance has been found to contain some pharmaceutical properties including of both antiviral and antifungal activities. Microbiological studies have identified more than seven periodontopathogens in the periodontal pockets, which less than 4 species were capnophile. The purpose of this study was to investigate the in ...

Aggressive periodontitis is characterized by rapid attachment and bone loss with no underlying systemic disease and is associated with specific bacteria like Actinobacillus actinomycetemcomitans (Aa) and Porphyromonas gingivalis (Pg). In this case series 25 patients were diagnosed with aggressive periodontitis by the aid of DNA probes for Aa and Pg and other periodontal pathogens. The use of DN...

The periodontopathic bacterium Actinobacillus actinomycetemcomitans possesses a 35-kDa periplasmic iron-repressible protein. Its regulation is mediated by the Fur protein, as was inferred from the Fur-binding consensus sequence at the -35 position of the gene for the 35-kDa protein and from the relaxed expression of the gene in a mutant with an altered Fur-binding sequence. The 35-kDa protein, ...

The mouth may provide an accessible model for studying bacterial interactions with human cells in vivo. Using fluorescent in situ hybridization and laser scanning confocal microscopy, we found that human buccal epithelial cells from 23 of 24 subjects were infected with intracellular bacteria, including the periodontal pathogens Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis, ...
