List Five Bacteria That Can Cause Urinary Tract Infection


UTI is one of the most common bacterial infections that can affect anyone at any age. Every second woman and every twentieth man get a UTI at some point in their lives. About 90% of UTIs are caused by bacteria traveling through the opening of the urethra and into the bladder. However, in today’s article, we will discuss the list of five bacteria that can cause urinary tract infections.

Why Do Urinary Tract Infections Happen?

When e coli is found in feces and around the anus, there is an increased risk of bacteria entering the urinary tract. A factor that leads to infection and increases the risk of an UTIs.

  • The partners’ genitals, anus, or fingers could be contaminated with bacteria
  • When a woman uses spermicide condoms five times within two weeks
  • Due to the holding of urine
  • Sex Toy

Remember that urinary tract infections (UTIs) are not spread from person to person like STDs, but they can be made worse by having sex. A UTI is caused by bacteria coming into contact with the urethra.

Five bacteria that cause urinary tract infections

These 5 bacteria can cause urinary tract infections escherichia coli, klebsiella pneumoniae, proteus mirabilis, enterococcus faecalis, and staphylococcus saprophyticus

  • Escherichia Coli

E. coli is the most common bacteria responsible for urinary tract infections (UTIs). It usually resides in the digestive tract but can enter the urinary tract through improper hygiene or sexual activity. E coli causes inflammation and infection in the urinary tract, resulting in symptoms such as frequent and painful urination.

  • Klebsiella Pneumonia

Klebsiella pneumoniae is a bacterium that is commonly found in the intestines. However, it can also cause UTI if it enters the urinary tract. It is often associated with healthcare-associated infections and can be more resistant to antibiotics than other bacteria. UTIs caused by Klebsiella pneumoniae may require specific antibiotic treatment.

  •  Proteus Mirabilis

Proteus mirabilis is a bacterium that frequently causes UTIs, especially in individuals with urinary tract abnormalities or catheterization. It has the ability to form crystalline biofilms and to clump, leading to the formation of kidney stones and recurrent infections. Symptoms of a Proteus mirabilis UTI include urinary urgency, pain and strong-smelling urine.

  •  Enterococcus Faecalis

Enterococcus philis is a bacterium commonly found in the intestines and female genital tract. This can lead to UTIs, especially in individuals with underlying urinary tract abnormalities or who have recently undergone urinary tract procedures. Enterococcus faecalis is often associated with complicated UTIs and can be resistant to many antibiotics.

  • Staphylococcus Saprophyticus

This bacteria is a less common cause of UTIs, but still important, especially in young sexually active women. Staphylococcus saprophyticus lives in the genital area and can climb up the urinary tract, causing an infection. It causes symptoms similar to other UTIs, including frequent urination and discomfort.

How Do I Check Myself for a Urinary Tract Infection?

It is possible to detect UTI at home by performing a urine test. Self-diagnosing a UTI can be done by purchasing a urine test strip or dipstick online or at your local drugstore.

First, you have to collect urine in an empty clean cup. Wet the urine test strip by holding it in the urine stream for 1 to 2 minutes. The number of minutes to wet it will be written on your brand. By using the chart on the home test kit, you can determine whether you have had a UTI.

In most cases, people do not realise whether they have UTI or not from a urine test strip, so they should go to their physician right away.

What is Best Antibiotic for Urinary Tract Infection?

Trimethoprim and sulfamethoxazole, nitrofurantoin, fosfomycin, amoxicillin, clavulanate, cefdinir, cephalexin, ciprofloxacin, levofloxacin, and doxycycline are the most common antibiotics used to treat urinary tract infections. The side effects of this antibiotic include nausea, vomiting, diarrhoea, and many more, so you should only take it under your doctor’s guidance.


Lower UTIs are more common than upper UTIs, but you should get them treated as soon as possible. In the case of upper urinary tract infections, they are serious, since they can damage the kidneys or spread to the bloodstream if left untreated.

The purpose of this article is to provide you with a list of five bacteria that can cause urinary tract infections. Thank you for reading. I hope it is useful to you or to someone you know.
