antibiotic resistance is an important problem in antibiotic treatment of infections, particularly in hospitals. tomatidine is a plant secondary metabolite with antimicrobial and antifungal effects. this study examined the possible synergistic effect tomatidine with several antibiotics against standard and clinical strains of staphylococcus aureus, enterococcus faecalis, pseudomonas aeruginosa a...

regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. the current study was performed to determine antimicrobial potenti...

the present work was designed to evaluate the in vitro lipid peroxidation inhibitory and antimicrobial activities of the methanol extract of phyllanthus niruri (mepn) (family:   euphorbiaceae) .   lipid peroxidation was measured by the optical density of the prepared solutions (10-320 µg/ml) and then the percent inhibition was calculated. ascorbate/feso 4 -induced peroxidation was inhibited by ...

random samples from asymptomatic leaves and branches of five native medicinal plants: stachys lavandulifolia, rumex pulcher, hypericum scabrum, starja bachteriarica and achillea kellalensis were collected from chaharmahal province of iran and examined for the presence of endophytic bacteria and fungi with biological activity. from 8 isolated endophytic fungi, all displayed considerable activity...

licorice (glycyrrhiza glabra l.) is an important medicinal plant. in this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. bacillus subtilis, enterococcus faecalis, klebsiella pneumoniae, pseudomonas aeruginosa, staphylococcus aureus and escherichia coli, and candida albicans were used as test organisms...

in the present study, the therapeutic potential of bacteriophages virulent to staphylococcus aureus associated with goat mastitis were isolated, identified and assessed. staphylococcus aureus (host or indicator bacterium) was isolated from a goat suffering from clinical mastitis. based on cultural, morphological, biochemical tests and amplification of s. aureus specific thermonuclease gene inpc...

Silk fabrics were modified by a treatment of silver nitrate solution (AgNO3) and polyvinylpyrrolidone (PVP) as a stabilizer then exposure to γ-irradiation to create antibacterial properties. Effects of the absorbed dose on treated fabrics were investigated. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) patterns were used to confirm the presence of silver nanoparticles (AgNP...

conclusions the overall results indicated that bacteriophages isolated from sewage exhibited excellent lytic activity against mrsa strains. in conclusion, bacteriophages can be further characterized and appear to be a promising candidate for phage therapy against mrsa in the future. results the phages exhibited good lytic activity against mrsa when tested in-vitro, and the highest activity was ...

introduction: in this study, the chemical composition and antimicrobial activity of essential oil of ziziphora clinopodiodes and its potential application as a natural preservative in reducing the indigenous microbial population of hamburger were investigated. method: essential oil of ziziphora clinopodiodes cultivated in iran was obtained by hydro-distillation method (hdm). chemical compositio...
