Where is ecoli bacteria normally found and what happens when it invades the urethra?

E. coli bacteria are normally found in the intestines of humans and animals, where they play a role in digestion. When E. coli invades the urethra, it can lead to urinary tract infections (UTIs), causing symptoms such as painful urination, increased urgency to urinate, and abdominal discomfort. If left untreated, these infections can spread to the bladder and kidneys, potentially leading to more severe health complications. Proper hygiene and hydration can help prevent these infections.
