Antimicrobial effect of water and alcohol extract of Cyperus on Actinobacillus actinomycetecomitans germ.

Abstract

This study includes the isolations and diagnoses of Actinobacillus actinomycetemcomitans from the patients with periodontal infections , isolation process has been done through using a selective medium named (Dentaid-1), Samples was cultivated anaerobically at 37°C for 48 hours. The aqueous and ethanolic extracts of the Cy penis rotundus plant were prepared and their inhibitory effect on the growth of these bacteria was carried on using the disk diffusion method. The results showed significant inhibitory effect on the growth of these bacteria at 50 , 100 and 200 ing /ml compared with tetracycline.
