Resistance of Candida species to conventional therapies has motivated the development antifungal nanocarriers based on iron oxide nanoparticles (IONPs) coated with chitosan (CS). This study evaluates effects IONPs-CS as carriers miconazole (MCZ) or fluconazole (FLZ) microcosm biofilms. Pooled saliva from two healthy volunteers supplemented C. albicans and glabrata was inoculum for biofilm forma...

The disruption of the balance in composition oral and throat microbiota due to overgrowth infectious biofilms may lead not only severe infections, but also serious, systemic complications resulting a permanent loss health or even death patient. Therefore, number hygienic measures are applied counter-act such threat, including provision locally active antiseptic agents. In this work, antimicrobi...

conclusions bacterial resistance against chlorhexidine is increasing. sub-mic doses of chlorhexidine digluconate can stimulate the formation of biofilm strains. materials and methods forty clinical isolates of escherichia coli, salmonella serotypes, staphylococcus. aureus and streptococcus agalactiae (10 isolates for each) were examined for chlorhexidine digluconate effects on biofilm formation...

The ability of uropathogenic E. coli (UPEC) to cause symptomatic UTI is associated with the expression of a variety of virulence factors. Biofilm formation enables UPEC to resist the flow of urine and increases its tolerance to antimicrobials and the host immune response. The measurement of biofilm formation in vitro is affected by the type of culture medium used. The aim of this study was to e...

introduction: pseudomonas aeruginosa is a gram-negative bacterium that considered as important opportunistic human pathogen. one of the mechanisms that help bacteria to tolerate survival in adverse conditions and resistance to antibiotics is biofilm formation through quorum sensing (qs) signals and toxin-antitoxin (ta) systems. qs and ta are two systems that have important roles in biofilm form...

the implementation of economic projects by targeting the subsidies can have a great effect on the costcompetitiveness of the industries and their products. the global steel industry has been considered as a basickey industry in the industrialized countries. it is also among the industries that may be seriously affected by theenforcement of subsidies. this industry, requiring energy and high-tec...
