uropathogenic E. coli (UPEC)
Uropathogenic E. coli (UPEC) are a specific type of bacteria that cause most urinary tract infections (UTIs). These bacteria normally live in the intestines but can sometimes reach the urinary system through the urethra. Once there, UPEC can stick to the lining of the urinary tract, multiply, and trigger infection. They have special mechanisms that help them evade the body's defenses and cause symptoms like burning during urination, frequent urge to urinate, and pain. Understanding UPEC is important for diagnosing and treating urinary tract infections effectively.
