Chemical composition and antibacterial effects of some essential oils individually and in combination with sodium benzoate against methicillin-resistant and .

Side effects of chemical preservatives and drug resistance have raised interest in use of herbal products. This study aimed to examine the chemical composition and antibacterial effects of , and essential oils individually and in combination with sodium benzoate against methicillin-resistant and The essential oils were analyzed by gas chromatography-mass spectrometry. Disc diffusion and microdilution assays were used for antimicrobial screening.

Antibacterial and Antifungal Activity of Holothuria leucospilota Isolated From Persian Gulf and Oman Sea.

Background: Emergence of antimicrobial resistance toward a number of conventional antibiotics has triggered the search for antimicrobial agents from a variety of sources including the marine environment.

Objectives: The aim of this study was to evaluate the antimicrobial potential of Holothuria leucospilota from Qeshm and Kharg Islands against some selected bacteria and fungi.

Materials And Methods: In this investigation, sea cucumbers from two coastal cities of Persian Gulf were collected in March and May 2011 and identified by the scale method according to the food and agriculture organization of the United Nations.

Chitosan and polyvinyl alcohol composite films containing nitrofurazone: preparation and evaluation.

Objective(s): The aim of this study was to insert nitrofurazone in a chitosan membrane to be used as a wound dressing.

Materials And Methods: Several blend films using chitosan (Cs) and polyvinyl alcohol (PVA), containing nitrofurazone were prepared by means of casting/solvent evaporating technique. Different characteristics such as mechanical properties, water vapor transmission rate (WVTR), oxygen permeability (OP), swelling ability (SW), differential scanning calorimetric (DSC), drug release profiles and antibacterial activity of the films were investigated.
