Susceptibility to caspofungin and fluconazole and Als1/Als3 gene expression in biofilm and dispersal cells of Candida albicans.
The biofilm of Candida albicans has been implicated as a source of bloodstream infections. Dispersal cells, as the final biofilm stage, are responsible for its spread. The aim of this study was to compare the susceptibility of biofilm and dispersal cells vs. planktonic cells (overnight liquid culture) of C. albicans to caspofungin (CAS) and fluconazole (FLU) when the drugs were added: i) at the...
متن کاملMetallochaperones Regulate Intracellular Copper Levels
Copper (Cu) is an important enzyme co-factor that is also extremely toxic at high intracellular concentrations, making active efflux mechanisms essential for preventing Cu accumulation. Here, we have investigated the mechanistic role of metallochaperones in regulating Cu efflux. We have constructed a computational model of Cu trafficking and efflux based on systems analysis of the Cu stress res...
متن کاملRelation of ALS 1 and ALS3 genes and fluconazole resistance in Candida albicans isolated from vaginal candidacies
Candida albicans is an opportunistic fungi that is able to thrive in many host niches, including the skin, mucosal, surfaces, the blood stream and internal organs. Agglutinin-like sequence (ALS) genes which could play a role in forming biofilms, adherence to host surfaces as a virulence factor and antifungal drug resistant. The purpose of the present study was to evaluate the presence ALS1 and ...
متن کاملIsolation and characterization of bacteria resistant to metallic copper surfaces.
Metallic copper alloys have recently attracted attention as a new antimicrobial weapon for areas where surface hygiene is paramount. Currently it is not understood on a molecular level how metallic copper kills microbes, but previous studies have demonstrated that a wide variety of bacteria, including Escherichia coli, Staphylococcus aureus, and Clostridium difficile, are inactivated within min...
متن کاملUltrastructural Analysis of Candida albicans When Exposed to Silver Nanoparticles
Candida albicans is the most common fungal pathogen in humans, and recently some studies have reported the antifungal activity of silver nanoparticles (AgNPs) against some Candida species. However, ultrastructural analyses on the interaction of AgNPs with these microorganisms have not been reported. In this work we evaluated the effect of AgNPs on C. albicans, and the minimum inhibitory concent...
