A person’s diet, acidity of urine may affect susceptibility to UTIs

The acidity of urine — as well as the presence of small molecules related to diet — may influence how well bacteria can grow in the urinary tract, a new study shows. The research, led by Jeffrey Henderson, MD, PhD, at Washington University School of Medicine in St. Louis, may have implications for treating urinary tract infections, which are among the most common bacterial infections worldwide.

Urinary tract infections steal from hosts’ defense arsenals

Humans have known for centuries that copper is a potent weapon against infection. New research shows that the bacteria that cause serious urinary tract infections “know” this, too, and steal copper to prevent the metal from being used against them. Blocking this thievery with a drug may significantly improve patients’ chances of fighting off infections, according to researchers.
