Commonly found colonizing the human microbiota, Candida albicans is a microorganism known for its ability to cause infections, mainly in vulvovaginal region, and responsible 85% 90% of candidiasis (VVC) cases. The development drug resistance C. isolates after long-term therapy with fluconazole an important complication solve new therapeutic strategies are required target this organism pathogenicity. In present study, phenyllactic acid (PLA) broad-spectrum antimicrobial compound was investigated antifungal antivirulence activities against clinical albicans. Previously characterized strains from women VVC ATCC90028 were used evaluate time dependent killing assay activity PLA showing MIC 7.5 mg mL-1 complete reduction viable cells detected by kinetics 4 h treatment PLA. Additionally, significantly reduced biomass metabolic biofilms impaired biofilm formation also changes ERG11, ALS3, HWP1 genes expression as qPCR. eradicated pre-formed showed confocal laser scanning microscopy (CLSM) observations. Furthermore, prolonged survival rate Galleria mellonella infected isolates. These results indicate that promising candidate novel safe agents candidiasis.

Candida auris represents an emerging pathogen that results in nosocomial infections and is considered a serious global health problem. The aim of this work was to evaluate the vitro antifungal efficacy Cinnamomum cassia essential oil (CC-EO) pure or formulated polycaprolactone (PCL) nanoparticles against ten clinical strains C. auris.nanoparticles PCL were produced using CC-EO (nano-CC-EO) cinnamaldehyde (CIN) through nanoprecipitation method. chemical profile both nano-CC-EO evaluated SPME sampling followed by GC-MS analysis. Micro-broth dilution tests performed fungistatic fungicidal effectiveness CIN, nano-formulated. Furthermore, checkerboard synergistic action with micafungin fluconazole conducted. Finally, biofilm disrupting activity formulations evaluated.GC-MS analysis shows different composition between nano-CC-EO. Moreover, microbiological analyses do not show any variation either towards planktonic form (MICCC-EO = 0.01 ± MICnano-CC-EO 0.02 0.01) form. No drugs tested found.both same antimicrobial are potential assets fight auris.

Infectious diseases caused by various nosocomial microorganisms affect worldwide both immunocompromised and relatively healthy persons. Bacteria fungi have different tools to evade antimicrobials, such as hydrolysis damaging the drug, efflux systems, formation of biofilm that significantly complicates treatment infection. Here, we show myrtenol potentiates antimicrobial biofilm-preventing activity conventional drugs against S. aureus C. albicans mono- dual-species cultures. In our study, two optical isomers, (−)-myrtenol (+)-myrtenol, been tested either antibacterials, antifungals, or enhancers drugs. (+)-Myrtenol demonstrated a synergistic effect with amikacin, fluconazole, benzalkonium chloride on 64–81% clinical isolates albicans, including MRSA fluconazole-resistant fungi, while increased properties amikacin fluconazole repress in half isolates. Furthermore, was able potentiate up sixteen-fold planktonic cells an aureus–C. mixed culture repressed adhesion aureus. The mechanism (+)-myrtenol synergy apparently driven membrane damage since terpenes led significant drop potential similar action chloride. Thus, due low toxicity myrtenol, it seems be promising agent increase efficiency infections bacteria genus Candida well fungal–bacterial infections, resistant strains.

The opportunistic human fungal pathogen Candida albicans produces and releases into the surrounding medium extracellular vesicles (EVs), which are involved in some processes as communication between cells host–pathogen interactions during infection. Here, we have conducted isolation of EVs produced by a clinical isolate C. biofilm formation proved their effect towards ability Gram-negative bacterial Klebsiella pneumoniae to adhere HaCaT form vitro. results represent first evidence an antagonistic action against bacteria.
