> many of the fungal species in question are widespread, which makes sample contamination a serious concern, says Iliev.

> Both research teams got most of their tissue and blood samples from databases, so the samples were not collected with the aim of minimizing fungal contamination, says Bhatt. Although the researchers developed methods to filter any potential contaminants out of the sequencing data, she would like to see the results replicated using samples taken in a sterile environment.

Uh what.
