Comparative antibacterial studies of mistletoes growing on two diffrent host plants in Akure North, Nigeria

Abstract

The antibacterial activity of 60 % methanolic leaves extracts of mistletoes (Viscum album) growing on cocoa and cola trees were tested on Bacillus cereus, Pseudomonas aeruginosa,Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi in vitro. Both the gram-positive and gramnegative organisms showed variable sensitivity to the extracts treatments. The results obtained indicated that extracts from both host plants had some antibacteria activities against the microorganisms when compared with standard antimicrobial agents (ciprofloxacin and sterptomycin) used as positive controls at P < 0.05 significant level. In general,extracts from cocoa (Theobroma cacao) plant showed more antimicrobial tendency than those from cola (Kola nitida) plant.
