In plain words

What the trial is, and whether it could suit you

Urinary tract infection (UTI) is one of the most common bacterial infections worldwide. It affects 150 million people annually. Treatment of patients with UTI entails a high consumption of antibiotics and large social and health costs. With this protocol, we want to elucidate alternative treatment methods for especially recurrent urinary tract infection. Bacteria have internal competitiveness (bacterial interference) and it is known that the non-pathogenic E.coli can outcompete the pathogenic E.coli in laboratory studies. We intend to strengthen the clinical evidence that it can be used as patient treatment through a clinical, placebo-controlled, double-blind trial at Odense University Hospital.
