Candida auris: From Multidrug Resistance to Pan-Resistant Strains.

ABSTRACT: Candida auris is an emerging multidrug-resistant fungus that is rapidly spreading worldwide. Currently, C. auris cases have been reported globally from >30 countries. Most reported infections involve critically ill patients in hospitals, mainly in intensive care unit settings. Infection with C. auris is associated with high mortality rates, and it is often resistant to multiple classes of antifungal drugs. Despite the rapid global spread, it is difficult to predict the actual burden of the infection as the standard laboratory methods fail to correctly identify the fungi. Longer stays in healthcare facilities, use of tracheostomies and percutaneous endoscopic gastrostomy tubes, ventilators in clinical care units and mobile equipment in healthcare settings are shown as major risk factors of C. auris infection. Due to its propensity to cause outbreaks and its antifungal resistance, C. auris poses a risk for patients in healthcare facilities. The emergence of ?pan-resistant C. auris strains in some areas is an alarming signal for the disease with limited treatment options, high mortality rates, and the ability of the pathogen to spread easily in healthcare settings. In this regard, susceptibility testing on clinical isolates, mainly for patients treated with echinocandins, is needed. Increasing awareness about C. auris infection and advancing the diagnostic methods ?are also essential for early detection and control of the deadly fungal infection.

Project description:Candida auris is a recently described pathogenic fungus that is causing invasive outbreaks on all continents. The fungus is of high concern given the numbers of multidrug-resistant strains that have been isolated in distinct sites across the globe. The fact that its diagnosis is still problematic suggests that the spreading of the pathogen remains underestimated. Notably, the molecular mechanisms of virulence and antifungal resistance employed by this new species are largely unknown. In the present work, we compared two clinical isolates of C. auris with distinct drug susceptibility profiles and a Candida albicans reference strain using a multi-omics approach. Our results show that, despite the distinct drug resistance profile, both C. auris isolates appear to be very similar, albeit with a few notable differences. However, compared to C. albicans both C. auris isolates have major differences regarding their carbon utilization and downstream lipid and protein content, suggesting a multifactorial mechanism of drug resistance. The molecular profile displayed by C. auris helps to explain the antifungal resistance and virulence phenotypes of this new emerging pathogen.IMPORTANCECandida auris was first described in Japan in 2009 and has now been the cause of significant outbreaks across the globe. The high number of isolates that are resistant to one or more antifungals, as well as the high mortality rates from patients with bloodstream infections, has attracted the attention of the medical mycology, infectious disease, and public health communities to this pathogenic fungus. In the current work, we performed a broad multi-omics approach on two clinical isolates isolated in New York, the most affected area in the United States and found that the omic profile of C. auris differs significantly from C. albicans In addition to our insights into C. auris carbon utilization and lipid and protein content, we believe that the availability of these data will enhance our ability to combat this rapidly emerging pathogenic yeast.
