Haj Elamin. E. Azhari, Mohammed. R.R

Abstract


The crude alcoholic extract of the plant corn silk was tested for its antibacterial activity against nine organisms: Klebsiella pneumoniae, Escherichia coli, Salmonella paratyphi A, Salmonella paratyphi, Staphylococcus aureus, Streptococcus pyogenes, Lactobacillus plantarum and Bacillus subtilis. The aquatic-ethanol extract of Zea mays (corn silk) was found to have inhibitory effect against Escherichia coli in the concentration of 02.5mg/ml whereas the minimum inhibitory concentration (MIC) for Klebsiella pneumoniae, Salmonella paratyphi A and Salmonella typhi was found to be 0.5mg/ml. Among the gram +ve bacteria studied, Zea mays (corn silk) aquatic-ethanol extract showed no inhibitory effect against Staphylococcus aureus and Streptococcus pyogenes but has MIC of 02.5 mg/ml against Bacillus subtilis and 0.5 mg/ml against Lactobacillus plantarum

Key words: Crude Alcoholic Extract, Zea mays, Corn Silk, Antibacterial Activity, Nine Organisms
