Powdered whole plant, leaves and inflorescence materials of Acmella calva (DC.) R.K. Jansen extracted with different solvents viz., aqueous, chloroform, acetone, ethanol and petroleum ether. The extracts were tested against three bacterial pathogens such as Streptococcus mutans, Streptococcus salivarius, Porphyromonas gingivalis and one lactic acid bacteria like Lactobacilli brevis for its antibacterial activity. The results obtained showed that among the five solvent extracts tested, the chloroform extract of whole plant, leaves and inflorescence was the most active against all the tested bacteria. The results suggested that A. calva can be used a potential medicinal plant for further investigations in medical microbiology against infective pathogens.
