Staphylococcus aureus is an important pathogen and produces a widespread infection. Increasing usage of antibiotic for staphylococcus aureus infections has created antibiotic resistance and subsequently new antibiotics should be produceed. Medicinal herbs with antimicrobial activity have had important roles in traditional medicine. The purpose of this study was to determine the antibacterial ac...

Antibacterial activities of different forms of peppermint (Mentha piperita) viz., aqueous infusion, decoction, juice and essential oil were investigated against 100 isolates belonging to 11 different species of Gram –ve bacilli viz., Escherichia coli (30), Klebsiella pneumoniae (25), Pseudomonas aeruginosa (15), Salmonella typhi (5), S. paratyphi A (1), S. paratyphi B (1), Proteus mirabilis (10...

In this study the attempt was made to evaluate the antimicrobial activity of various solvent extracts of fruit of Piper longum L. against different gram positive and gram negative bacteria by using disk diffusion method. The petroleum ether extract was resistant towards all the tested bacterial strains while ethyl acetate was highly active. Among all the gram positive bacteria Staphylococcus au...
