Antimicrobial activity of Cynodon dactylon against MDR bacteria

Abstract

The antimicrobial activity of Cynodon dactylon (Grass) were determined and compared against 2 Gram+ve bacteria (Staphylococcus aureus and Bacillus cereus) and 2 Gram-ve bacteria (Salmonella typhi and Escherichia coli), which are Multi Drug Resistant (MDR). The Cynodon dactylon leaves were crushed and their extract was taken in Propanol. The efficiency of the extract were tested against MDR bacteria through well diffusion assay. In this endeavor the antimicrobial assay extract show inhibitory or antimicrobial activity against MDR bacteria. The propanol extract of Cynodon dactylon showed maximum antimicrobial activity against Staphylococcus aureus (Gram+ve) followed by Bacillus cereus (Gram+ve) while there is no antimicrobial activity obtained against Salmonella typhi (Gram-ve) and Escherichia coli (Gram-ve). On the basis of present finding it was concluded that the extract possess antimicrobial and pharmacological properties, hence can be used parallel to synthetic drugs which have undesirable side effects.
