abstract       background and objective: due to the continuous increase of multidrug-resistant acinetobacter baumannii strains around the world, decision making for an effective treatment of infections caused by this organism depends on the results of antimicrobial susceptibility tests. in this study, the validity of disk diffusion and e-test methods was assessed by their comparison with the re...

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...

the infections risk related to pathogenic germs increases at the present time considering the increased resistance which certain microbes acquire, whose usual antibiotics are ineffective to treat the infectious disease. the aim of this study was to determine antimicrobial effect of the aqueous and ethanolic extracts of lavandula stoechas l. and rosmarinus officinalis l. on listeria monocytogene...

The minimum inhibitory concentrations of penicillin and cephalothin necessary to inhibit growth of most anaerobic bacteria were reduced to a susceptible level by 1 to 5 mug of clavulanic acid per ml. In most cases, minimum inhibitory concentrations of cefoxitin were not affected.
