Summary

This study looks at whether testing wastewater from nursing homes can predict how many residents carry antibiotic-resistant bacteria. Researchers will collect stool or swab samples from 1,600 residents and compare them to bacteria levels in the facility's wastewater. The goal is to create a model that uses wastewater data to monitor resistance, reducing the need for individual testing.
