The effect of oil, ethanol and total alkaloids extracted from the seeds of Nigella sativa L.(Ranunculaceae) by three different methods(soxhlet, solvent extraction, and reflux techniques) on the growth of Staphylococcus aureus was evaluated. Five concentrations (100 µl, 130 µl, 150 µl, 170 µl, 200 µl) of these extracts were utilized.The ethanol and...

Alkaloids were separated from black seed by using two type of solvents; ethanol and chloroform, we obtained two fractions of alkaloid (A1 & A2). Separated fractions were tested in different concentrations (50, 75, 100, 125 and 150 mg/ml) against four types of bacteria (Staphylococcus aureus , Bacillus cereus, E. coli and Pseudomonas spp.). The resu...

Different factorial experiments were conducted during 2008-2009 in the laboratories of Biology Department, College of Science, University of Salahaddin-Erbil, to determine the effects of aqueous and ethanol extracts of pomegranate (Punica granatum L.) and oak gall (Quercus infectoria L.) at 0, 5, 10, 15 and 20% of raw extracts to control Penicilliu...

Objective(s): Salmonella typhi, is a serious global health threat because it causes typhoid fever, a severe systemic infection. According to the World Health Organization, millions of cases of typhoid are recorded annually, and thousands of people die from it. To combat this pathogen, new medications are required. The current study aims to study th...

Pomegranate Peel extractions used as quorum sensing inhibitor (QSI) against Staphylococcus aureus (which isolated from soft white cheese in local market), different solvents used to obtain different active ingredient groups, minimum inhibitory concentration of each group were determined then sub-inhibitory concentration was used as (QSI). We get th...

In this study, the antibacterial activity of methanol extract of henna (Lawsonia inermis) leaves, ethanol extract of pomegranate (Punica granatum) peel, volatile oil of sesame (Sesamum indicum) and peanut (Arachis hypogaea) were investigated against some Gram-positive and Gram-negative bacteria includingStaphylococcus aureus, Bacillus cereus, Esche...

Different solvents were used for sumac extractions to find different active compounds in each fraction, and these fractions were tested on Staphylococcus aureus (which isolated from soft white cheese), the (MIC) minimum inhibitory concentration of each fraction were measured then sub-inhibitory concentration (SIC) was used. We found that all fracti...

Different culture media in different volumes were exposed to microwave (MW) irradiation for 2, 3 and 4 minutes to investigate the ability of MW to destroy microorganisms and compared with media sterilized by conventional autoclaving method. MW sterilized media were screened for microbial growth. Exposure of different microorganisms to microwave irr...

This study presents the inhibitory effect of breast milk and formula milk against some pathogenic bacteria (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus spp and pseudomonas aeruginosa) isolated from infants suffering from different infections. The results showed that the breast milk had antibacterial activity against test...
