Bacteriophages Lurk In Your Bathroom, But Don’t Worry

It sounds like something from an advertisement for bathroom cleaner: Researchers found over 600 different viruses, most of which are new to science, in samples taken from showerheads and toothbrushes. The viruses, however, are unlikely to affect humans. They are bacteriophages, a type of virus that preys on bacteria. The expedition into bathroom biodiversity was recently published in the journal Frontiers in Microbiomes.

Around a hundred years ago in the former Soviet Union, there were major efforts to develop bacteriophages for medical use. The approach really didn’t catch on in Western countries, overshadowed there by the rise of conventional antibiotics like penicillin. But with some diseases developing resistance to those conventional antibiotics, there’s been increased interest in phages as part of an antibacterial toolkit.

Dr. Erica Hartmann, an associate professor in the department of Civil & Environmental Engineering at Northwestern University, joins Ira to talk about what researchers found when they took a close look at a collection of bathroom samples, and how phage research has advanced in recent years.
