An internal fragment representing approximately 85% of sod genes from seven Gram-positive bacteria was amplified by using degenerate primers in a polymerase chain reaction assay. The DNA sequences of sod polymerase chain reaction products from Clostridium perfringens, Enterococcus faecalis, Enterococcus faecium, Lactococcus lactis, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus ...

Introduction: Individuals with poor oral health have a greater risk factor for systemic diseases. Caries, periodontal disease, and root canal infections are common dental diseases caused by dominance of Streptococcus mutans, Porphyromonas gingivalis, Enterococcus faecalis bacteria (S. P. E. faecalis). An alternative way to prevent is use herbal medicine as one the active ingredients mouthwash o...

When the thiol-oxidizing agent diamide was added to a batch culture of Streptococcus faecalis during exponential growth, the specific activity of inorganic pyrophosphatase (EC 3.6.1.1) decreased to the level observed in the stationary phase. The effect of diamide was completely reversed by reduced glutathione. Furthermore, the ratio of reduced to oxidized glutathione and the specific activity o...

Objective The objective of this study was to evaluate the antimicrobial activity of Mineral trioxide aggregate e Portland cement against some selected cariogenic bacteria. Methods Wells were made of approximately 0.5 mm in diameter, in solid culture media and immediately filled with cement. Twelve samples of each material were obtained for the realization of the agar diffusion method. These sam...
