New research by a team of scientists at the University of Wisconsin is shedding new light on what makes the multidrug-resistant and deadly yeast Candida auris so effective at spreading among hospital patients.
In a series of experiments involving lab-created sweat and pig skin, the scientists showed that C auris forms dense, multilayered biofilms on skin that persist even in dry conditions. The scientists say the findings may help explain why the pathogen colonizes the skin, and why it’s spreading so easily in hospitals.
“We think that skin colonization involves biofilm growth,” said lead study author Jeniel Nett, MD, PhD, an assistant professor at the University of Wisconsin School of Medicine and Public Health. “Because these communities resist drying and persist in the environment, this mode of growth is likely involved in the spread of Candida auris in hospital settings.”
