Antibiotic-resistant H. pylori has been detected in Peru’s drinking water, raising concerns that water systems may act as hidden reservoirs for infection and antimicrobial resistance.

The findings suggest drinking-water systems themselves may serve as environmental reservoirs for this cancer-linked pathogen.
