Serratia Marcescens

This page is about Serratia marcescens. We look at diagnosis and treatment, how these infections occur, and medical malpractice lawsuits that involve this potentially deadly infection.

Serratia Marcescens Diagnosis and Treatment

Serratia marcescens is a dangerous infection that can kill you. This species of bacteria is known to be a highly opportunistic pathogen commonly involved in hospital-acquired infections. Serratia marcescens is commonly found in the environment, particularly in consistently damp conditions where the bacteria proliferate.

S. marcescens can frequently be seen on tile and shower corners or at the water line of a toilet bowl, where it appears as a pink or orange filmy residue. Seldom-used toilets are actually the ideal breeding ground for s. marcescens because of the standing water in the bowl. Aside from shower tiles and toilets, the s. marcescens bacteria can also usually be found in soil and human and animal feces.

Serratia Marcescens Treatment

The symptoms of a Serratia marcescens infection can vary depending on the site of the infection. Here are the potential – and this is a laundry list – symptoms associated with various types of infections caused by Serratia marcescens:

1. Respiratory Infections:
   • Cough
   • Shortness of breath
   • Fever
   • Chest pain
2. Urinary Tract Infections (UTIs):
   • Pain or a burning sensation during urination
   • Frequent urination
   • Cloudy or bloody urine
   • Lower abdominal pain
   • Fever
3. Wound Infections:
   • Redness and swelling around the wound
   • Pain at the wound site
   • Discharge of pus
   • Fever
4. Bloodstream Infections (Bacteremia or Sepsis):
   • Fever and chills
   • Rapid heartbeat
   • Rapid breathing
   • Low blood pressure
   • Confusion or altered mental state
5. Eye Infections (such as Endophthalmitis or Keratitis):
   • Redness of the eye
   • Pain and swelling in the eye
   • Discharge from the eye
   • Blurred vision
6. Meningitis (infection of the membranes surrounding the brain and spinal cord):
   • Severe headache
   • Stiff neck
   • Sensitivity to light
   • Nausea and vomiting
   • Fever
7. Osteomyelitis (bone infection):
   • Pain in the infected bone
   • Swelling, warmth, and redness over the affected area
   • Fever

Of course, the hard part is that these same symptoms are symptoms of many other ailments as well.  So the key is diagnosing the infection quickly by ruling out S. marcescens.

Serratia Marcescens Infections

At one point, Serratia marcescens was believed to be a completely harmless organism. But scientific research shows that s. marcescens can be a harmful bacterium that is very dangerous to humans.  Serratia marcescens is now a common cause of human infections in the respiratory tract, digestive tract, and wound site infection.

Serratia marcescens is a common cause of so-called hospital-acquired infections in patients and healthcare workers. S. marcescens is believed to be responsible for approximately 2% of all documented cases of hospital-acquired infection. This is because S. marcescens multiples on medical equipment and facilities (e.g., showers, toilets, etc.) found in hospitals.

S. marcescens bacteria is known to cause various types of human infections, including urinary tract infections (UTIs), respiratory tract infections, conjunctivitis, tear duct infections, and keratitis. Although extremely rare, it can also cause pneumonia and meningitis.

Minimizing the Risk of Serratia Marcescens Infection

Once s. marcescens has established itself on a surface; completely eliminating it can be challenging. The bacteria can be eradicated only with a bleach-based disinfectant or cleaner. The best methods for controlling the development and spread of s. marcescens include:

• Regular Cleaning: thoroughly and regularly cleaning all surfaces with a bleach-based cleaner or disinfectant is the most effective prevention tool. Kitchen and bathroom surfaces and other areas exposed to water are higher-risk areas that require more frequent cleaning.
• Disinfecting & Rinsing: on surfaces where the pink slime associated with s. marcescens has previously developed, complete disinfection and rinsing may be required. Chlorine bleach products are required to properly disinfect for s. marcescens. Disinfectants should remain on the surface for 20 minutes before thoroughly rinsing away with fresh water.
• Avoid Scratching Surfaces: When cleaning for s. marcescens take precautions to avoid scratching any surfaces with abrasives. Scratches on a smooth surface can create an ideal breeding ground for s. marcescens.

Treatment for Serratia Marcescens Infections

Treatment options for s. marcescens-related infections involve antibiotic medication. The Serratia marcescens bacterium is known to be highly resistant to most first-generation antibiotics like penicillin. This includes commonly used medications such as amoxicillin, ampicillin, and many other cephalosporin medications. This resistance to antibiotic medications has made s. Marcescens infections are somewhat difficult to treat effectively.

The difficulty of treating infections caused by S. marcescens is one of the reasons why prevention is often considered so important. This is particularly true in a hospital setting where s. marcescens is known to be a problem. Hospitals must ensure proper cleaning and disinfecting of equipment and facilities to prevent S. marcescens from developing and infecting patients.

Serratia Marcescens Infection and Medical Malpractice

When a hospital-acquired infection is related to Serratia marcescens, it is most likely the result of negligent practices at the hospital, such as failures to clean surfaces on a regular basis properly. Hospital patients who develop infections from s. marcescens at the hospital may be entitled to bring a hospital malpractice lawsuit and get financial compensation for their injuries.

Origins of Malpractice Lawsuits

S. marcescens malpractice lawsuits usually originate from less from treatment mistakes – like most infection lawsuits – and more from allowing the infections in the first place:

1. Failure to maintain sterile environments: Sterility in medical environments, especially operation theaters and intensive care units, is paramount. The presence of S. marcescens indicates a failure in maintaining such an environment.
2. Improper sterilization of medical equipment: S. marcescens can thrive in residues left on improperly cleaned or sterilized medical equipment.
3. Contaminated intravenous (IV) fluids or medications: These are directly introduced into the bloodstream, providing a direct route for the bacterium to cause systemic infections.

Serratia Marcescens Infection Settlement Amounts and Jury Payouts

Below are some sample settlement compensation amounts and jury awards in Serratia marcescens medical malpractice lawsuits. Obviously, you cannot predict the settlement amount in your case by looking at these results because every case is different. But our lawyers think they are helpful both to victims and lawyers handling Serratia marcescens malpractice claims.
