Before 2020 and the COVID-19 pandemic, concern among infectious disease specialists was rising about Candida auris, an emerging fungal pathogen that is often drug-resistant and difficult to eradicate from hospitals.
Many people know Candida can cause mouth or vaginal infections and diaper rashes. According to the CDC, Candida also can cause invasive infections in the bloodstream, particularly in hospital or nursing home patients with weakened immune systems. About 30 percent of patients with an invasive Candida infection die – and C. auris is just one particularly hardy variety.
Emory Antibiotic Resistance Center director David Weiss and colleagues have identified a combination of existing antifungal drugs (micafungin and amphotericin B) with enhanced activity against C. auris when used together. The results – in vitro only, so far — were published in a letter to The Lancet Microbe. Postdoctoral fellow Siddharth Jaggavarapu was the first author. Weiss reports his team continues to investigate combination approaches against C. auris.
