Global prevalence of infectious diseases caused by microorganism is a major public health problem. Resistance against antibiotics of abundant bacteria is gradually acquiring. Therefore, investigation for new inventive plant materials with antimicrobial activity has become an insistent necessity. The present study aimed to investigate the antimicrobial potential of ethanol and aqueous aerial extracts of Mikania scandens, Croton bonplandianum Baill and Eupatorium triplinerve against gram positive, gram negative bacteria and fungus strains by using agar well diffusion assays and their activities were further determined by Minimum inhibitory concentration (MIC), Minimum bactericidal concentration (MBC), Minimum fungal concentration (MFC) assays. | In vitro antimicrobial effectiveness of selected medicinal plants extract against pathogenic organisms
