The first aim of this study is to evaluate the in vitro antimicrobial activity of the essential oil and two extracts of Saharan myrtle: Myrtus nivellei Batt & Trab. For this purpose, paper disc-diffusion method and micro-dilution test were used. As far as the antimicrobial activity is concerned the essential oil exhibited higher ones against S. epidermidis (MIC=0.28mg/ml), S. typhi (MIC=0.56mg/...

Two methods for determining the sensitivity of Haemophilus ducreyi to antimicrobial agents were compared; an agar dilution method and the Etest. The MICs of seven antimicrobial agents; penicillin V, ampicillin, trimethoprim, tetracycline, chloramphenicol, erythromycin and ciprofloxacin were determined for 20 strains of H. ducreyi. The MICs determined with the Etest and with the agar dilution me...

Antimicrobial assays are important tools to test and screen the inhibitory effects of myriad compounds against microorganisms before establishing their inhibitory spectra (broad vs. narrow). Knowledge of the inhibitory spectra of antimicrobial compounds before their application in the fields of agriculture, biotechnology, and medicine is crucial. Various conventional and contemporary methods ar...

PURPOSE Antimicrobial wound dressings are becoming more popular and are routinely used in the treatment of chronic and problematic wounds. Despite the ever-growing number and types of these antimicrobial products, many practitioners often do not report significant clinical differences between various common antimicrobial wound dressings despite wide variations in cost. Although these dressings ...

Background: Although various surface disinfectants have been introduced, most of them are toxic. The use of natural antimicrobial agent e.g. phytol, extracted from Leptadenia pyrotechnica is a new strategy. The aim of this study was to evaluate the antimicrobial activity, toxicity, and stability of phytol. Methods: The serial concentrations of phytol were prepared, and separately incubated with...

the focus of this study was antimicrobial membrane-activity of actinomycetes isolated from soils of iran. in this work, soil samples were collected from desert and farming zones of northern and central iran. a total number of 45 actinomycetes were isolated from the soil samples. in the primary screening performed to evaluate antimicrobial activity, isolated microorganisms were analyzed in terms...

A common method for measuring the drug-specific minimum inhibitory concentration (MIC) of an antibacterial agent is via a two-fold broth dilution test known as the MIC test. Because this procedure implicitly rounds data upward, inference based on unadjusted measurements is biased and overestimates bacterial resistance to a drug. We detail this test procedure and its associated bias, which, in m...
