Plumbing systems may be a common source of human infections, say researchers studying the prevalence of the fungus Fusarium in bathroom sink drains.

“With about two-thirds of sinks found to harbor Fusarium, it’s clear that those buildings’ inhabitants are exposed to these fungi on a regular basis,” says lead investigator Dylan Short, who recently completed his doctorate in plant pathology. “This strongly supports the hypothesis that plumbing-surface biofilms serve as reservoirs for human pathogenic fusaria.”
