Biofilm Formation of Salmonella
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...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
A mutation in rpoS enhances biofilm formation in Escherichia coli during exponential phase of growth.
Biofilm formation in Escherichia coli is a process that involves slow growth and stress conditions where several molecular signals and growth phase regulated genes are involved. Here we show that rpoS mutant strains (defective in the stress regulator sigma(S)) exhibit an increased production of biofilm, especially in the exponential phase of growth. Our results indicate that rpoS mutants produc...
متن کاملEvaluation of the presence and time-variable expression levels of rpoS, relA and mazf genes during biofilm formation in Staphylococcus epidermidis
Background and purpose:Staphylococcus epidermidis is an opportunistic pathogen that is involved in the development of infections associated with the use of implants and medical devices. Biofilm formation is one of the most important virulence factors of this microorganism, which vastly depends on various factors, including different proteins. In the present study, the expression levels of three...
متن کاملHydrophobicity of Residue 128 of the Stress-Inducible Sigma Factor RpoS Is Critical for Its Activity
RpoS is a key stress-inducible sigma factor that regulates stress resistance genes in Escherichia coli, such as the katE gene encoding catalase HPII and the glg genes encoding glycogen synthesis proteins. Monitoring RpoS activity can provide information on the stress sensitivity of E. coli isolates in clinical settings because the RpoS in these isolates is often mutated. In the present study, w...
