The occurrences of antimicrobial activity of ferns were studied. The present paper deals with the antimicrobial activities of some ethno-medicinally important ferns which are very common in West Mednapore District as well as South West Bengal, against Gram-positive and Gram-negative bacterial pathogens. The plants were extracted with different solvents (70% Ethanol, methanol and acetone) and controlled by deionized water (DW). Our experiment reveals significant results like Dryopteris showed remarkable antimicrobial activities among all the selected ferns.
Key words: Antimicrobial activity, ferns, ethnomedicinal uses, Eastern India.
