Urinary tract infection is one of the most serious infectious disease in world , This study aimed to isolate and diagnose bacteria that cause UTI then evaluate its ability form a biofilm. 100 urine samples were collected for group patients attending Al-Diwaniyah Teaching Hospital, who confirmed have at different ages. The results showed presence bacteria. Escherichia coli proteus spp all sample...

in this work, the adsorption of the anionic dye, congo red (cr), from aqueous solution by using tea waste (tw) has been carried out at 30 °c. the equilibrium sorption isotherms and kinetics were investigated. the equilibrium adsorption was studied by the langmuir and freundlich models of adsorption. the experimental results manifested that the langmuir isotherm was the best model for the adsorp...

Introduction: Staphylococci are increasingly being recognized for their biofilm forming capacity leading to chronic infections and treatment failures. Owing to their burden on healthcare services, the choice of the method of biofilm detection in a routine diagnostic laboratory needs to be established. Methods: Institutional Ethics Committee approval was obtained before study initiation. Clinica...

The ability of Congo red to form complexes with α-proteins, human growth hormone and human interferon-α2b, was found by absorption difference spectroscopy. A human growth hormone– Congo red complex was isolated by gel-permeation chromatography, and its visible absorption spectrum was registered in comparison to free dye. The ability of Congo red to induce dimerization of human growth hormone wa...

Prion diseases are fatal neurodegenerative disorders. Identification of possible therapeutic tools is important in the search for a potential treatment for these diseases. Congo red is an azo dye that has been used for many years to detect abnormal prion protein in the brains of diseased patients or animals. Congo red has little therapeutic potential for the treatment of these diseases due to t...

Azo, anthroquinone and triphenylmethane dyes are the major classes of synthetic colourants, which are difficult to degrade and have received considerable attention. Congo red, a diazo dye, is considered as a xenobiotic compound, and is recalcitrant to biodegradative processes. Nevertheless, during the last few years it has been demonstrated that several fungi, under certain environmental condit...

Agar plate-based biofilm of enterobacteria like Escherichia coli is characterized by expression of the extracellular matrix components amyloid curli and cellulose exopolysaccharide, which can be visually enhanced upon addition of the dye Congo Red, resulting in a red, dry, and rough (rdar) colony morphology. Expression of the rdar morphotype depends on the transcriptional regulator CsgD and occ...
