In 2009, a never-before-seen yeast emerged from the ear canal of a 70-year-old Japanese lady. Unfortunately, this yeast – known as Candida auris – is a health menace, having now spread around the world and become resistant to multiple drugs. A n
occasionally sexually reproduces is actually not as crazy as it sounds. We already know that a much more famous type of yeast,The team didn't catchin the act, but they were able to analyze the fungal and mitochondrial genes in 1,285 strains of fungus. This allowed them to look at the genetic differences between the five clades ofThe team found some recombination, but most of it occurred before the yeast split into the five clades.
But even infrequent sex can potentially cause new resistances or other ways of making this pathogen worse for us humans. "The research tells us that this fungus has recombined in the past and can recombine in nature, which enables it to generate new genetic variants rather quickly," explains McMaster's University microbial geneticist Jianping Xu.
"That may sound frightening, but it's a double-edged sword. Because we learned they could recombine in nature, we could possibly replicate the process in the lab, which could allow us to understand the genetic controls of virulence and drug resistance and potentially other traits that make it such a dangerous pathogen, much faster.", looking deep at its genes to discover a sex life is a good place to start.
