Whole-genome sequencing reveals new secrets about killer fungus — ScienceDaily

New analysis from the College of Exeter reviews the biggest ever whole-genome sequencing venture for the possibly deadly yeast an infection Candida glabrata from hospitals throughout Scotland.

Candida glabrata is a kind of yeast that may trigger illness in people. It mostly impacts the urinary tract, genitals, mouth, and the bloodstream. If it’s not caught, these infections can turn out to be lethal. It additionally has a really excessive resistance to sure antifungal medication, so understanding why resistance happens is vital to understanding easy methods to deal with it successfully.

The brand new analysis, revealed in Genetics, used samples from eight hospitals in Scotland to sequence the genome of Candida glabrata. This led to the invention of quite a lot of new data on the species. This contains data on how they reproduce and the genetic range. It additionally discovered that genes that make it extra prone to be infectious have a bonus for survival, and the drug-resistance genes usually evolve inside sufferers.

The invention of this data offers scientists a bonus in relation to treating candida glabrata. A greater understanding of the genes concerned permits researchers to focus their work in ways in which weren’t potential earlier than. It additionally helps support understanding on how the pathogen spreads, which is essential to figuring out infections.

Dr Rhys Farrer, one of many Principal Investigators on the MRC Centre for Medical Mycology on the College of Exeter, stated: “Our examine sheds new gentle on the genetic range of Candida glabrata. We’ve got demonstrated that this lethal human fungal pathogen is being unfold between continents, most likely by people, and recombining to type new populations, which is probably going contributing to its excessive virulence and rising drug resistance.”

The analysis was funded by the Medical Analysis Council and the Wellcome Belief.
