Candida albicans causes a variety of clinical manifestations through multiple virulence factors that act simultaneously to overcome the immune system and invade the host tissues. Owing to the limited number of antifungal agents available, new candidiasis therapeutic strategies are required. Previous studies have demonstrated that the metabolites produced by Streptococcus mutans lead to a decrease in the number of Candida cells.

Unlabelled: Previous studies showed that the crude extract obtained from Streptococcus mutans inhibited the growth of Candida albicans reference strains. In this study, we evaluated whether the antifungal effects of S. mutans extract can be extended to clinical Candida isolates, including C.

In the oral cavity, species form mixed biofilms with , a pathogenic bacterium that can secrete molecules with antifungal activity. In this study, we extracted and fractioned culture filtrate of , seeking antifungal agents capable of inhibiting the biofilms, filamentation, and candidiasis by . Active UA159 supernatant filtrate components were extracted via liquid-liquid partition and fractionated on a C-18 silica column to resolve fraction 1 (SM-F1) and fraction 2 (SM-F2).

Probiotics might provide an alternative approach for the control of oral candidiasis. However, studies on the antifungal activity of probiotics in the oral cavity are based on the consumption of yogurt or other dietary products, and it is necessary to use appropriate biomaterials and specific strains to obtain probiotic formulations targeted for local oral administration. In this study, we impregnated gellan gum, a natural biopolymer used as a food additive, with a probiotic and investigated its antifungal activity against 28.

Article Synopsis
  • The orphan drug auranofin has shown promising antimicrobial properties, effective against over 500 clinical bacterial isolates, including drug-resistant strains.
  • The minimal inhibitory concentrations for auranofin were identified between 0.125 and 1 mg/l, demonstrating strong antimicrobial activity.
  • Extended exposure to auranofin did not lead to resistance in the methicillin-resistant strain MW2 over a 25-day period, suggesting that current resistance mechanisms do not impact its efficacy.

The oral cavity is home to a microbial community of more than 800 species. This important microbiome is formed by commensal and opportunistic bacteria, fungi and viruses. Several distinct habitats within the mouth support heterogeneous microbial communities that constitute an important link between oral and general health.

Porphyromonas gingivalis is an important pathogen in the development of periodontal disease. Our study investigated if the treatment with antimicrobial photodynamic therapy (aPDT) that employs a nontoxic dye, followed by irradiation with harmless visible light can attenuate the experimental infection of P. gingivalis in Galleria mellonella.

In this study, we evaluated the interactions between Candida albicans, Candida krusei and Candida glabrata in mixed infections. Initially, these interactions were studied in biofilms formed in vitro. CFU/mL values of C.
