Extra chromosomes help Candida auris resist antifungal drugs
Narayanan and colleagues report that copied sections of DNA and extra chromosomes help the fungus Candida auris resist antifungal drugs. The peer-reviewed paper appears in Nature Communications.
The usual view is that resistance comes mainly from mutations in the genes that drugs target. The authors say changes in the structure of the genome also play a part. Candida auris is a drug-resistant fungus that has spread in hospitals worldwide, so this may matter for how laboratories detect and treat it. Details of the sample sizes and methods were not available, and the finding comes from the authors' own laboratory work.
