The present study is conducted to analyze the antifungal and antibacterial potential of some plants against three species of human pathogenic microbes i.e. E. coli, Salmonella, and Malassezia. The antimicrobial activity of ethanolic and methanolic extracts of Calotropis procera, Prosopis juliflora, and Ziziphus nummularia was assessed by employing a good diffusion method in agar. Overall results demonstrated the highly significant activity of Ziziphus nummularia against E. coli, Ziziphus nummularia, and Calotropis procera against Salmonella and Calotropis procera against Malassezia. Of three dilutions used, 1.0 ml, 0.8 ml, and 0.6 ml, the 1 ml dilution of methanolic extract of Ziziphus nummularia and Calotropis procera exhibited potential effectiveness against E. coli and Salmonella. While 1.0 ml dilution of ethanolic extract of Calotropis procera showed the best antibacterial activity. However, Prosopis juliflora leaf extract was found to be less effective against selected pathogens.
