  Background and Objective: Microbial biofilms are responsible for 65% of human infections, and are resistance to antibiotics. Pseudomonas aeruginosa is one of the most important biofilm producing bacteria. This review tries to explain the last mechanisms of Pseudomonas aeruginosa biofilm formation, the reasons for its resistance to antimicrobial agents, as well as new preventive measures and a...

Background and Objectives: Synthesis of silver nanoparticles (AgNPs) using plant extract is cost effective, while, one of the applications of AgNPs is its antimicrobial and anti-biofilm activities. The aim of this study was to investigate the anti-biofilm activity of synthesized AgNPs using A. dendroides against antibiotic resistant and biofilm forming clinical isolates of Klebsiella pneumoniae...

Background and Objectives: Biofilms are a community of bacteria on surfaces coated with extracellular polymeric materials, and one strategy to remove biofilms is to use nanoparticles. The aim of this study was to synthesize green zinc oxide (ZnO) nanoparticles and determine its anti-biofilm effects on biofilm gene expression in multidrug-resistant Klebsiella pneumoniae strains. Materials and M...

Background & Aims: Salmonella Typhimurium is among the most important food-borne disease. This study was conducted to investigate the anti-biofilm effect of the S. Typhimurium phage against Salmonella formed in chicken meat model. Materials & Methods: The effects of different phage concentrations (104, 106 and 108 PFU/mL) with two contact times (10 and 20 min) on one and 7 days old biof...

Background: Klebsiella pneumoniae is one of the most important hospital opportunistic pathogens that have become resistant to many antibiotics due to biofilm formation. The aim of this study was to synthesize copper nanoparticles using Artemisia scoparia extract, to investigate its antimicrobial and anti-biofilm effects against K. pneumoniae strains. Methods: In this experimental study, 100 cli...

Background & Aims: B.cepacia is one of the causative agents of health care associated infections which have the ability of attachment to different surfaces and biofilm formation is one of the most important virulence factors in pathogenesis of this microorganism. Nanoparticles are key components which are considered for the designing of new antimicrobial agents, no studies have been done on the...

Introduction & Objective: Microorganisms form biomass as biofilm in response to many factors, in order to adapt to hostile extracellular environments and biocides. Using different herbal compounds are of those strategies to deal with biofilm. It has been proved that plants extracts such as pomegranate, raspberry and chamomile essential oils have anti-biofilm effects. This study aimed to evalu...

The natural compound zosteric acid, or p-(sulfoxy)cinnamic acid (ZA), is proposed as an alternative biocide-free agent suitable for preventive or integrative anti-biofilm approaches. Despite its potential, the lack of information concerning the structural and molecular mechanism of action involved in its anti-biofilm activity has limited efforts to generate more potent anti-biofilm strategies. ...
