what bacteria causes uti

The bacteria that most commonly causes urinary tract infections (UTIs) is Escherichia coli (E. coli) . This type of bacteria is commonly found in the gastrointestinal (GI) tract and can enter the urinary tract through the urethra, leading to an infection in any part of the urinary system, including the bladder and urethra. While E. coli is the most common cause of UTIs, other bacteria can also cause these infections, but E. coli is responsible for about 90% of cases. Its important to note that UTIs can be caused by micro-organisms, usually bacteria, and E. coli is the most prevalent among them. Proper hygiene, such as wiping from front to back after using the toilet, can help prevent the spread of E. coli from the anus to the urethra, reducing the risk of UTIs.
