Background Staphylococcus aureus, methicillin-resistant and Escherichia coli, multidrug-resistant included in the list of antibiotic-resistant priority pathogens from WHO. As multidrug-resistant bacteria problem is increasing, it is necessary to probe new sources for identifying antimicrobial compounds. Medicinal plants represent a rich source of antimicrobial agents. One of the potential plant...

the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...

This study was carried out to evaluate the antibacterial activity of aqueous and organic extracts of Thymus capitatus L. (Lamiaceae) leaves and stems. Dried ground powder leaves and stems were extracted with water (aqueous extracts), ethanol, dichloromethane and hexane (Soxhlet extracts). The antibacterial activity of these extracts was evaluated against bacteria using disc diffusion method. Th...

The concept of biological control for health maintenance has received widespread attention during the last few years. Therefore, the main objective of this work was to look for active substances that could be used as antibacterial agents. To achieve this target, two different extract (Methanol and Acetone) from Spirulina platensis was examined. The algal extracts were tested in vitro for their ...

in different folk medicine ziziphus spina-christi is used for different purposes such as pneumonia, dysentery, scorpion stings, cough, constipation, intestinal worms and fever. the aim of this study was evaluation and comparing the antibacterial activity of methanolic and ethanolic extracts of ziziphus spina –christi as well as subsequent structural changes in affected bacteria. for this purpos...

The purpose of this study was to observe the antibacterial activity of aqueous methanolic extracts of 10 plants against 2-gram negative bacteria (Pasteurella multocida, Escherichia coli) and 3-gram positive bacteria (Bacillus cereus, Staphylococcus aureus, Corynebacterium bovis) by using disc diffusion method. The minimum inhibitory concentration (MIC) was determined by agar well diffusion meth...

BACKGROUND Excessive production of free radicals has been implicated in many diseases including cancer. They are highly reactive and bring about oxidation of biomolecules i.e., proteins, lipids and nucleic acids which are associated with many degenerative diseases. Natural products acting as antioxidants have ability to neutralize free radicals and their actions and hence they mitigate their ha...

Antibaterial activity against Escherichia coli, proteus vulgaris, pseudomonas aeruginosa and staphylococcus aureus was tested for the petroleum ether (60-80°C) chloroform and aqueous leaf extract of strobilanthus kunthiana by disc diffusion method. Profound antibacterial activity was observed for all the leaf extract.

background and objectives: resistance towards reveling antibiotics has captured great interest in evaluating the antimicrobial properties of the natural plants. taraxacum mongolicum is widely used as a folklore medicinal plant for its diuretic, antirheumatic and anti-inflammatory properties. though there are some reports on antimicrobial properties of taraxacum mongolicum, studies on antibacter...

UNLABELLED Cefoxitin is a potent inducer of the mecA regulatory system. It is being recommended for detection of methicillin resistance in Staphylococcus aureus (MRSA) when using disk diffusion testing. The aim of our study was to evaluate the efficacy of cefoxitin disc diffusion test to characterize MRSA and compare it with oxacillin agar screening and detection of mecA gene by PCR. MATERIAL...
