background : lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. the inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of pseudomonas aeruginosa. the isolates were selected as the most resistant strains when challenged with ant...

objectives in the present study, we evaluated the antibacterial activity of capsella bursa-pastoris alone and also combined with glycyrrhiza glabra against streptococcus mutans, s. sanguis, actinomyces viscosus, enterococcus faecalis as oral pathogens. conclusions c. bursa-pastoris and its mixture with g. glabra are suggested as appropriate candidates to control dental caries and endodontic inf...

198 Lactic acid bacteria (LAB) were isolated from Iranian milk samples. Almost all isolatedLAB showed inhibitory activity towards E. coli and S. aureus as Gram negative and Grampositive indicators, respectively. No role was observed for hydrogen peroxide in the activity ofall isolated strains while organic acids proved a prominent role in all detected inhibitoryactivities. Within isolated LAB, ...

Background: German chamomile (Matricaria recotita) as a medicinal plant has several therapeutic effects. Since the extract of this plant contains a high amount of α-bisabolol (Terpenoid) its antibacterial properties can be considered. Staphylococcus aureus as a pathogenic bacterium is important in clinical situations and food hygiene. So, investigation of effects of antibacterial compounds agai...

BACKGROUND The purpose of this study was to evaluate the antimicrobial activity of two nitric oxide donors, ie, S-nitrosoglutathione (GSNO) and S-nitroso-N-acetylcysteine (SNAC), against clinical isolates from patients with infectious keratitis. METHODS Reference broth microdilution assays were performed to determine the minimum inhibitory and bactericidal concentrations for GSNO and SNAC aga...
