Which microorganism is responsible for the majority of urinary tract infections?
Step 1: Understand what a urinary tract infection (UTI) is. It is an infection in any part of the urinary system, including the kidneys, bladder, or urethra.
Step 2: Learn about microorganisms. These are tiny living things that can only be seen with a microscope, including bacteria, viruses, and fungi.
Step 3: Identify the common causes of UTIs. Many different microorganisms can cause UTIs, but some are more common than others.
Step 4: Focus on Escherichia coli (E. coli). This is a type of bacteria that normally lives in the intestines.
Step 5: Recognize that E. coli is responsible for most UTIs. Studies show that it causes about 80-90% of urinary tract infections.
Step 6: Conclude that if someone has a UTI, it is very likely caused by E. coli.
