Researchers evaluated the antimicrobial effectiveness of silver-containing showerheads under realistic conditions and found that they do not effectively reduce pathogen levels as claimed. Silver exposure varied among different fixtures, affecting microbial composition but not overall pathogen concentration. The study suggests that silver might encourage biofilm formation, potentially increasing microbial resistance instead of reducing it. Antimicrobial [...]from SciTechDaily https://ift.tt/Gyg7CfF
