Bathroom Biodiversity and Bacteriophages
Research has revealed a surprising diversity of viruses, specifically bacteriophages, lurking in household bathrooms. These viruses prey on bacteria and pose no threat to human health, as they do not infect people. Samples obtained from toothbrushes and showerheads demonstrated that each location hosts a unique mix of viruses, showcasing significant variability between different samples. This biodiversity suggests that studying these environments may provide insights into the broader microbial ecosystems present in the built environments where people spend most of their time.
