background and aim: in recent years, due to the indiscriminate and irrational use of synthetic drugs, the resistance of pathogenic microorganisms has increased; therefore, new compounds are vitally needed. the purpose of this study was to investigate the effect of ethanolic and aqueous extracts of berberis vulgaris on escherichia coli, klebsiella pneumoniae, proteus mirabilis, citrobacter frund...

The minimal inhibitory concentrations of 30 antibiotics were determined by the agar dilution method for 17 penicillinase-positive and 50 penicillinase-negative strains of Neisseria gonorrhoeae. The latter included 42 strains that were penicillin susceptible (pen S) (minimal inhibitory concentration, <0.125 mug/ml) and 8 strains with intermediate resistance to penicillin (pen I; minimal inhibito...
BACKGROUND Medications from Anthroposophical Medicine (AM) are clinically used for the treatment of infections within a whole medical system but have not yet been evaluated regarding antibacterial effects. The aims of this study was to investigate antibacterial activity of AM medications in cell culture. METHODS Screening of AM drug registers for preparations used to treat any kind of infecti...
BACKGROUND Multidrug resistant microorganisms are a growing challenge and new substances that can be useful to treat infections due to these microorganisms are needed. Silver nanoparticle may be a future option for treatment of these infections, however, the methods described in vitro to evaluate the inhibitory effect are controversial. RESULTS This study evaluated the in vitro activity of si...
In this study, based on our previous derivatives of naphtho[2,3-b]furan-4,9-diones were synthesized and their antimicrobial activities evaluated. The screening these naphthoquinones revealed that the fluorine-containing NQ008 compound exhibited potent broad against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), Gram-negative bacteria, fungi. results ratio m...
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...
In the present study, antibacterial activity of aqueous and organic extracts of Psidium guajava leaves was evaluated against multidrug resistant (MDR) clinical isolates of Staphylococcus aureus strains collected from hospitals in northern (Malabar region) Kerala. The strains which exhibited resistance against all the antibiotics tested was selected for antibacterial assays. Minimum inhibitory c...
BACKGROUND The present study was designed to investigate the antibacterial activities of the methanol extract of three edible plants, namely Xanthosoma mafaffa, Moringa oleifera and Passiflora edulis and their synergistic effects with some commonly used antibiotics against MDR Gram-negative bacteria expressing active efflux pumps. METHODS Broth microdilution method was used to determine the m...
