Background: Candida auris is a drug-resistant fungal pathogen. Diagnosing it is challenging due to the need for modern techniques. This study aims to evaluate the usefulness of Enterobacteriaceae culture media in screening and identifying Candida auris, as those media are accessible in resource-limited laboratories.
Method: The study used various yeast strains, including Candida auris, to challenge bacteriologic media and evaluated the effectiveness of different Enterobacteriaceae differential and selective media in identifying and differentiating Candida auris from other yeasts.
Results: All yeasts can grow on all Enterobacteriaceae differential and selective media during various incubation times, resulting in variable colony sizes. Simon's Citrate Agar medium can differentiate Candida auris and other members of C. haemulonii complex from other yeasts.
Conclusion: Although definitive identification of Candida auris is challenging and requires specific methods, Citrate Agar could be a preliminary screening method in source-limited regions.

Infections caused by fungal pathogens are a global health problem, and have created an urgent need for new antimicrobial strategies. This report details the synthesis of lipidated 2-vinyl-4,4-dimethyl-5-oxazolone (VDM) oligomers an optimized Cu(0)-mediated reversible-deactivation radical polymerization (RDRP) approach. Cholesterol-Br was used as an initiator to synthesize a library of oligo-VDM (degree of polymerisation = 5, 10, 15, 20, and 25), with an α-terminal cholesterol group.

In this study, we investigated the interactions between and , , , and in mixed infections. Initially, these interactions were studied qualitatively and quantitatively in dual-species biofilms formed in vitro. The MTT assays, determination of the total CFU/mL, and SEM analysis showed that interacted differentially with the other spp.

New technology has opened opportunities for research and exploration of deep-water ecosystems, highlighting deep-sea coral reefs as a rich source of novel bioactive natural products. During our ongoing investigation of the chemodiversity of the Irish deep sea and the soft coral we report 12 unreported cadinene-like functionalized sesquiterpenes, anthoteibinenes F-Q. The metabolites were isolated using both bioassay- and H NMR-guided approaches.
