Antibacterial activity of plant extracts against oral and skin pathogens

Abstract

The aim of this study is to examine the antibacterial activity of plant extracts. Both broth dilution and disc diffusion methods were used to assess the antibacterial activity of these extracts against skin and oral pathogens. Eryngium caucaseum Trautv, Eryngium bungei Boiss and Adiantum capillus-veneris have shown antibacterial activity against Streptococcus pyogenes, Streptococcus mutans, Staphylococcus aureus and Streptococcus sanguis. E. caucaseum Trautv showed the highest inhibition zone (> 30 mm) against S. pyogenes. The growth of S. pyogenes was remarkably inhibited by the ethanolic extract of the three plant extracts.
