Microbial infections outbreak in aquatics are important challenges, and farmers have major difficulties dealing with microbes especially regarding their antibiotic resistance. The purpose of this study was comparative evaluating of antimicrobial activity of silver nanoparticles (Ag NPs) against one gram-positive bacteria (Bacillus spp) and a gram-negative (Vibrio harveyi). In this experimental ...
Abstract: Background and objectives: Antibiotic resistant to Antimicrobial agents is one of the most important concern in hospitals, which can lead to increased costs, treatment fails and mortality rates. The aim of this study was identification of Gram-negative bacilli resistant to extended-spectrum β-lactamase Enzymes (ESBLs) and determination of the effect of silver nanoparticles on the...
Background and Objective: One of the most common bacterial infections in the children is urinary tract infection (UTI) that its early diagnosis and proper treatment has high importance and analysis of typing and antibiotic resistance of isolated bacteria from urine of children with different sex and ages can help empirical therapy of UTI before preparing lab data. Materials and Methods: The da...
Background: Treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. The aim of this study was to determine the multidrug resistance (MDR) pattern of the bacteria causing chronic sinusitis in north of Iran. Methods: This cross-sectional study was carried out on patients with chronic sinusitis. Bacterial susceptibility to antimicrobial agents was determi...
background and objective: diabetes mellitus is one of the main problems in health systems in the world. diabetic foot infections (dfi) is one of the main complications and the most cause of non-traumatic lower limb amputation .this study aimed to determine the prevalence of bacteria involved in dfi and their antibiotic resistance in patients with dfi diagnosis. patients and methods: this desc...
Received: 14 April, 2009 Accepted: 21 Oct, 2009 Abstract Background & Aims: Antimicrobial resistance among bacterial pathogens is a worldwide problem. The selection of initial treatment is made on an empiric basis and susceptibility testing is important to modify empirical therapy, especially for treatment of common bacterial pathogens. The aim of the present study was to determine the antimi...
