    2019-11-1 · 1. Introduction. Urinary tract infections (UTIs) are very common disease that occurs in people of all ages. In general, UTIs are defined as the presence of urinary symptoms (e.g. frequency, dysuria, and pyuria) and have 10 4 CFU mL or more pathogens in urine. It is reported that Escherichia coli (E. coli) infection is the most typical cause of UTIs, and Staphylococcus aureus (S. aureus) is a ...
