P. aeruginosa has been mentioned as the major causative agents of nosocomial infections. Pseudomonas infections are often serious and show different resistance to treatment due to distribution of antimicrobial resistance. Meanwhile, some strains are also able to form biofilm during contamination, which help bacteria to be even more persisyant to yreatment. We examined the antibiotic resistance ...

conclusions the results of this study suggest that e. hebecarpa extracts can be used to inhibit the planktonic and biofilm forms of these selected bacteria. objectives in an effort to combat these industrial and medical bacterial biofilm problems, our study aims to determine the antimicrobial effect of euphorbia hebecarpa. materials and methods the inhibition efficiency of alcoholic extracts on...

background and purpose: in people wearing dentures, the growth of various candida species under the prosthesis leads to the formation of biofilm, which can play the role of a reservoir for candida and other kinds of microbes. since nano-chitosan particles can cause lasting antimicrobial activity, a more recent approach that utilizes acrylic resins with nano-chitosan particles is proposed. there...

conclusions the bacterial isolates exhibited strong biofilm formation potential, while the extracts of acacia arabica significantly inhibited biofilm formation among the isolates and, therefore, could be executed in the development of cost-effective biofilm inhibitor medicines. results pseudomonas aeruginosa (kc417303-05), staphylococcus hemolyticus (kc417306), and staphylococcus hominis (kc417...

conclusions similarly to other geographical regions of iran, the sccmec type iii mrsa strain was the most frequently isolated strain from patients in gorgan. staphylococcal cassette chromosome mec type iii showed fewer virulence factors compared to other sccmec types. results the most common sccmec type was type iii, with a frequency rate of 76%, followed by types iv, i, and v, with frequency r...

background and objectives: biofilms are structural communities of bacterial cells enshrined in a self produced polymeric matrix. the studies on biofilm formation of pasteurella multocida have become imperative since it is a respiratory pathogen and its biofilm mode could possibly be one of its virulence factors for survival inside a host. the present study describes a biofilm assay for p. multo...

biofilm formation in bacteria is an important survival strategy. biofilm of probiotic bacillus subtilis consist of long chains of cells that are covered by a polymeric matrix of exopolysaccharides. this bacterium is known as one of the most effective biocontrol agents against plant pathogens and has a high ability in biofilm formation. this study was aimed to investigate the effect of some envi...

wound infections are a common cause of staphylococcal infections. an ability of s.aureus is to adhere and form biofilm on host surfaces. biofilm is an exopolysaccharide, a slime matrix around multiple layers of cells and is mediated by expression of the icaadbc operon. the present study evaluated the biofilm forming capacity and the presence of icaad gene among s.aureus isolated from wound infe...

Objective(s) Methicillin-resistant Staphylococcus aureus (MRSA) is an important cause of nosocomial and community infections. Biofilm formation, mediated by a polysaccharide intercellular adhesin (PIA) and encoded by the ica operon, is considered to be an important virulence factor in both S. epidermidis and S. aureus. However, the clinical impact of the ica locus and PIA production is less w...
