background: the aim of this study was to investigate the antibiotic susceptibility pattern as well as the phenotypic and genotypic biofilm formation ability of staphylococcus aureus isolates from patients with urinary tract infection (uti). methods: a total of 39 isolates of s. aureus were collected from patients with uti. the antibiotic susceptibility patterns of the isolates were determined b...

objectives we investigated the potential relationships between biofilm formation and prevalence of virulence genes (asa1, esp, cyla, and gele/spre), and antimicrobial resistance genes (aac (6’)/aph (2”) in enterococcus faecalis isolated from patients with urinary tract infection. patients and methods in this survey 95 e. faecalis isolates from patients with urinary tract infections staying at s...

Objective: Intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. The present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. Methods: In the present st...

Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment of infections. Nanomedicines such as chitosan can carry multiple drugs and improve the therapeutic effects of antibiotics. Objectives: The study aimed to synthesis and characterization of ciprofloxacin loaded chitosan nanoparticle for eradication biofilm of P. aeroginosa. Methods: Cipro-CS microparticles...

Salmonella spp. may form biofilm, and bacteria in biofilm are more resistant to drug, chemical, physical and mechanical stresses, and host immune system. The progress on biofilm research will be helpful for the development of new tools and strategies to prevent biofilm-related disease and decontaminate biofilm-derived Salmonella in food produc‐ tion. In this review, we present a comprehensive o...

introduction bacterial biofilms can be both useful and harmful based on their combination and locations. biofilm formation occurs as a stepwise process. their formation in liquid transportation pipes used for milking system and drinking water in animal farms may create some problems and is a potential source of pollution. speed of biofilm formation depends on many factors including: constructio...

objective: microorganisms are responsible for many problems in industry and medicine because of biofilm formation. therefore, this study was aimed to examine the effect of thymus vulgaris (t. vulgaris) extracts on the planktonic form and biofilm structures of six pathogenic bacteria. materials and methods: antimicrobial activities of the plant extracts against the planktonic form of the bacteri...

  Biofilm of Pseudomonas aeruginosa, an opportunistic pathogen, can cause serious health problems, such as chronic infections, especially in immunocompromised patients. Many studies have suggested administration of new generation of antibiotics, as P. aeruginosa biofilms have developed high resistance to antimicrobial drugs. This study reports the inhibitory effect of three medicinal plant extr...

Background & Objective: Staphylococcus aureus, especially methicillin-resistant S. aureus (MRSA), represent serious nosocomial and community infections. Biofilm formation as an important virulence factor may be affected by sub-inhibitory levels of antibiotics. Few studies examined the effects of all therapeutic antimicrobial agents on...

Background: Biofilm formation by Pseudomonas aeruginosa is a serious concern in treatment of diseases and medical industries. Natural products that originate in plants can influence microbial biofilm formation. The effect of ethyl acetate, methanol and water- methanol extracts of Quercus brantii on biofilm formation and biofilm disruption of P. aeruginosa were investigated in this study. Methods...
