This research investigates how the body’s natural use of copper—through nutritional immunity—can be leveraged to combat antibiotic-resistant E. coli infections in urinary tract infections. By understanding bacterial susceptibility to copper, this work aims to identify novel, host-inspired strategies for treating UTIs.

Urban farms in Baltimore need reliable irrigation water. This research tested harvested rainwater for E. coli, Listeria, and Salmonella, and evaluated two treatments: sand–iron filtration and peracetic acid sanitizing. Both reduced E. coli, and sanitizing eliminated Listeria. Produce remained contamination-free, suggesting treated rainwater is a viable supplemental irrigation source.
