Abstract:

Introduction: Solanum melogena L. or egg plant is one of few cultivated Solanaceous species originating from the old world. Methods: To determine antimicrobial effects of egg plant, well agar diffusion assay for bacteria and colony diameter method for fungi were used. Crude extracts of different parts of Solanum melogena L. (egg plant) were tested for their antimicrobial activities against seven pathogenic microorganisms that include two strains of fungi (dermatophytes) and five strains of bacteria. Results: Root and fruit extracts showed significant effects on tested microorganisms. Epidermophyton floccosum considered the most susceptible fungus for extract of these parts with MIC value of 15 and 28 mg/ml respectively. Meanwhile, the bacterium Proteus vulgaris exhibited susceptibility to all tested extracts with less MIC value. Conclusions: Crude extracts of different parts of S. melogena showed variable potential effects on various types of pathogenic microorganisms.

Key words: Bacteria, Dermatophytes, Egg plant, Antimicrobial action.
