PATHOLOGY

Detailed explanation-1: -The most common bacteria found to cause UTIs is Escherichia coli (E. coli). Other bacteria can cause UTI, but E. coli is the culprit about 90 percent of the time.

Detailed explanation-2: -Antibiotics are the standard treatment for UTIs because they kill the bacteria responsible for the infections. Most UTIs develop when bacteria enter the urinary tract from outside the body. The species most likely to cause UTIs include: E. coli, which causes up to 90% of all bladder infections.

Detailed explanation-3: -For that reason, up to 10, 000 colonies of bacteria/ml are considered normal. Greater than 100, 000 colonies/ml represents urinary tract infection.
