Cruciferous vegetables contain glucobrassicin which, during metabolism, yields indole-3-carbinol (I3C). The aim of this study was to find whether indole-3-carbinol caused apoptosis and its mechanism in Candida albicans. We found that treatment of Candida albicans with indole-3-carbinol significantly increased the reactive oxygen species and hydroxyl radical accumulation. The hydroxyl radical is one of the most active components of oxygen, and it is the end product of an oxidative damage cellular death pathway. We investigated the general phenotypes of apoptosis and then investigated whether there were other distinct markers of apoptosis. Furthermore, the effects of thiourea as a hydroxyl radical scavenger and protective effect of trehalose, which is the result of the fungal immune system, was also assured. This study indicates that indole-3-carbinol has apoptosis effects, including a production of hydroxyl radicals, cytochrome c release and activation of metacaspase. Both hydroxyl radicals and metacaspases triggered apoptosis in Candida albicans.

is a prevalent fungal pathogen responsible for infections in humans. As described recently, nanometer-sized extracellular vesicles (EVs) produced by play a crucial role in the pathogenesis of infection by facilitating host inflammatory responses and intercellular communication. This study investigates the functional properties of EVs released by biofilms formed by two strains-3147 (ATCC 10231) and SC5314-in eliciting host responses.

We developed a cost-effective platform combining microbial extract prefractionation with rapid MS/MS-bioinformatics-based dereplication to efficiently prioritize new antifungal scaffolds. Screening and revealed novel lipopeptaibiotics, coniotins, from WAC11161, which were undetectable in crude extracts.

Background: Invasive Candida infections (ICI) are the most common invasive fungal infections in solid organ transplant recipients. There are limited contemporary data on the risk factors for infection in heart transplant (HT) recipients especially since the expansion of temporary mechanical circulatory support (MCS) use.
Methods: This was a case-control study conducted at a tertiary care academic hospital of HT recipients from January 2022 to January 2024.

Background: Severe pulmonary infection is the primary cause of death in children aged < 5 years. The early identification of pathogenic bacteria and targeted anti-infective therapies can significantly improve the prognosis of children with severe infections. This study aims to provide a reference for the rational use of antibiotics at an early stage in children with severe pulmonary infections.

Introduction: Cymbopogon martini, Syzygium aromaticum, and Cupressus sempervirens are used for antimicrobial purposes in the worldwide. Both their extracts and essential oil contents are rich in active ingredients.
Objective: The aim of this study was to investigate the inhibitory effect of Cymbopogon martini essential oil (CMEO), Syzygium aromaticum essential oil (SAEO) and Cupressus sempervirens essential oil (CSEO) on Candida albicans biofilm formation on heat-polymerized polymethyl methacrylate (PMMA) samples in vitro and in silico.
