The many faces of Candida auris: Phenotypic and strain variation in an emerging pathogen.

Candida auris is an emerging fungal pathogen with unusual evolutionary history-there are multiple distinct phylogeographic clades showing a near simultaneous transition from a currently unknown reservoir to nosocomial pathogen. Each of these clades has experienced different selective pressures over time, likely resulting in selection for genotypes with differential fitness or phenotypic consequences when introduced to new environments. We also observe diversification within clades, providing additional opportunities for phenotypic differences.

A -specific adhesin, Scf1 governs surface association, colonization, and virulence.

is an emerging fungal pathogen responsible for health care-associated outbreaks that arise from persistent surface and skin colonization. We characterized the arsenal of adhesins used by and discovered an uncharacterized adhesin, Surface Colonization Factor (Scf1), and a conserved adhesin, Iff4109, that are essential for the colonization of inert surfaces and mammalian hosts. is apparently specific to , and its expression mediates adhesion to inert and biological surfaces across isolates from all five clades.

Forward and reverse genetic dissection of morphogenesis identifies filament-competent Candida auris strains.

Candida auris is an emerging healthcare-associated pathogen of global concern. Recent reports have identified C. auris isolates that grow in cellular aggregates or filaments, often without a clear genetic explanation.

Monitoring Inflammasome Priming and Activation in Response to Candida albicans.

Candida albicans is a common mucosal colonizer, as well as a cause of lethal invasive fungal infections. The major predisposing factor for invasive fungal disease is a compromised immune system. One component of the host immune response to fungal infection is the activation of the inflammasome, a multimeric protein complex that is critical for regulating host pro-inflammatory responses.
