The antimicrobial activity of ethanol extract obtained from Thevetia peruviana was tested against bacterial species of Escherichia coli ATCC 69314, Streptococcus lactis NCIM50038, Enterobacter aerogenes NCIM 2340, Alcaligenes faecalis ATCC 15246, Pseudomonas aeruginosa NCIM 2200, Proteus vulgaris ATCC 6380 and fungal species of Fusarium oxysporum NCIM 1008, Alternaria helianthii ATCC 201540, Curvularia lunata ATCC 34477, Aspergillus niger NCIM 1207 and Penicillium spp NCIM 741. Better antimicrobial activity was observed with the extracts showed maximumactivity against E. coli, Enterobacter aerogenes, Alcaligenes faecalis. Among different fungi tested A. niger and Penicillium spp were found to be more sensitive to crude extract when compared to others. A considerable reduction in the sporulation was also recorded.
