Killer fungus copies its whole genome to dodge drugs

A new study adds an unexpected chapter to the story of antifungal resistance. Researchers led by the University of Exeter and City St George's, University of London, found that the fungus Candida auris can create multiple versions of its entire genome. Alongside this, it mutates a gene that plays a role in cell wall integrity, called CRZ1.

Why it matters: resistance is not always a single, simple change. When a pathogen can reshape its genetic blueprint under drug pressure, treatment strategies built on older assumptions may need to be rethought. For researchers, clinicians and anyone working in biotech or infection control, this is a useful reminder to watch for adaptive mechanisms that go beyond the obvious.

It also highlights how interdisciplinary collaboration between universities can uncover patterns that a single lab might miss. Curious how others in the field see the implications.
