Influence of polyphenols on bacterial biofilm formation and quorum-sensing.

Many bacteria utilize sophisticated regulatory systems to ensure that some functions are only expressed when a particular population density has been reached. The term 'quorum-sensing' has been coined to describe this form of density-dependent gene regulation which relies on the production and perception of small signal molecules by bacterial cells. As in many pathogenic bacteria the production...

بررسی وجود باند ژن rsbA و تاثیر اسید میریستیک در بیماری زایی پروتئوس میرابیلیس جدا شده از عفونت های ادراری

Abstract Introduction: Bacteria communicate with each other by using molecular chemical signal, which are called autoinducer. By the increase of concentration of these signals, which is the result of increase cellular density, they coordinate gene expression in a microbial community. This process is called Quorum sensing. Considering the importance of urine tract infections prominent role of Qu...

Analysis of ciprofloxacin and gentamicin diffusion in Proteus mirabilis O18 biofilm by laser interferometry method.

Laser interferometry is a measurement technique used in physical sciences, with a potential for new applications in microbiology. Our previously studies, focused on the quantitative analysis of antibiotics diffusion through membranes or their releasing from gel structure, indicate that this method might be useful in analysis of substances diffusion across the bacterial biofilms. As antibiotic -...

Periodontal pathogens produce quorum sensing signal molecules.

Different species of bacteria important in the composition of dental plaque were tested for production of extracellular autoinducer-like activities that stimulate the expression of the luminescence genes in Vibrio harveyi. Several strains of Prevotella intermedia, Fusobacterium nucleatum, and Porphyromonas gingivalis were found to produce such activities. Interestingly, these bacteria belong to...
