UTI caused by methicillin-susceptible Staphylococcus epidermidis

Understanding Staphylococcus Epidermidis and UTIs

Staphylococcus epidermidis, or S. epidermidis, is a bacterium found in the environment. It is also found on healthy skin and in the mouth and is a common cause for infection in humans. The bacteria can cause different types of infections, including urinary tract infections (UTIs).

When S. epidermidis is the cause of a UTI, it is referred to as a methicillin-susceptible staphylococcus epidermidis (MSSE) infection. This means it is susceptible to certain antibiotics that are effective at treating the infection.

Signs and Symptoms of UTIs Caused by S. epidermidis

UTI caused by MSSE can present differently depending on the person and site of infection, but some of the common symptoms can include:

  • Pain or burning sensation when urinating
  • Frequent bathroom trips or an urge to urinate frequently
  • Cloudy or bloody urine
  • Pain in the lower abdomen or lower back
  • Pain in the flank or groin area
  • Fever

If a UTI caused by S. epidermidis is suspected, it is important to see a doctor for diagnosis and treatment. UTIs left untreated can lead to additional health complications.

Diagnosis and Treatment

Doctors typically will perform a physical exam and take a urine sample for testing. From the urine sample, they can see if the S. epidermidis is present and determine if it is methicillin-susceptible. Based on this information, the doctor will determine the best course of action for treatment.

The most common form of treatment for UTIs caused by MSSE is antibiotics. Depending on the severity of the infection, the doctor may prescribe an antiseptic or antibiotic ointment or a tablet or pill. In some cases, the doctor may recommend a combination of both.

It is important to take the full course of antibiotics or antiseptic as prescribed by the doctor. This will help ensure the infection is cured and reduce the chance of the infection returning or becoming more severe.


Staphylococcus epidermidis is a common bacterium in the environment. When present, it can cause UTIs, which are referred to as methicillin-susceptible staphylococcus epidermidis infections. These infections are typically treated with antibiotics or antiseptic ointments.

It is important to seek medical attention if you suspect you have a UTI caused by S. epidermidis. If left untreated, it can lead to more serious health complications.
