outbreaks,and urinary tract and wound infections, is abundant in damp environments (Figure). It can be easily found in bathrooms, including shower corners and basins, where it appears as a pink–orange–red discoloration, due to the pigment known as prodigiosin.

Where is Serratia marcescens commonly found?

Serratia marcescens is commonly found in the environment, particularly in consistently damp conditions where the bacteria grow rapidly. 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.

At what site is Serratia normally found?

It is commonly found in the respiratory and urinary tracts of hospitalized adults and in the gastrointestinal systems of children. Due to its abundant presence in the environment, and its preference for damp conditions, S.

How common is Serratia marcescens?

Serratia marcescens, a motile, gram negative bacillus, which has been classified as a member of the family, Enterobacteriaceae, is widespread in the environment, but it is a rare cause of human disease.

How do you know if you have Serratia marcescens?

Symptoms may include fever, frequent urination, dysuria, pyuria, or pain upon urination. In 90% of cases, patients have a history of recent surgery or instrumentation of the urinary tract.

How does Serratia marcescens enter the body?

marcescens infections are known to be transmitted through hand-to-hand contact by medical personnel. In this case, solutions used for medical purposes, catheterizations, and needle punctures can be contaminated and infect patients(31). Patients may also be infected with S.

Why is there a pink ring in my toilet?

Toilets often develop a pink or slightly orange ring around the bowl right at the waterline, especially if the toilet is rarely used. It probably isn't rust or a mineral. The bad news is that slimy, anaerobic bacteria called Serratia Marcescens cause this ring.

Is Serratia marcescens airborne?

Serratia is an airborne bacteria and can not survive in your chlorinated water supply. These airborne bacteria can come from any number of naturally occurring sources and the condition can be aggravated if you remove chlorine using an activated carbon filter.

How is Serratia transmitted?

MODE OF TRANSMISSION: Ingestion of contaminated foods and direct contact ³. Nosocomial transmission may occur by hand contact from hospital personnel and other patients. Fomites may also spread Serratia.

What disinfectant kills Serratia marcescens?

Though Serratia will not survive in chlorinated drinking water, the bacteria can grow in toilets where water is left standing long enough for the chlorine to dissipate. To kill the bacteria, clean affected surfaces with a strong chlorine bleach solution.

How do you get rid of Serratia marcescens in the toilet?

A very easy homemade mixture that you can use to clean Serratia marcescens is baking soda mixed with dish detergent (a 4:1 ratio works best). After rinsing this mixture off, continue cleaning with vinegar. Let this soak and then clean and rinse.

How do you fight Serratia marcescens?

Serratia infections should be treated with an aminoglycoside plus an antipseudomonal beta-lactam, as the single use of a beta-lactam can select for resistant strains. Most strains are susceptible to amikacin, but reports indicate increasing resistance to gentamicin and tobramycin.

Is Serratia marcescens normal flora?

Serratia species are gram-negative bacilli of the Enterobacteriaceae group of bacteria, although they are not a common component of healthy human fecal flora.

Is Serratia marcescens harmful to humans?

In rare cases, Serratia marcescens can be deadly.

Along with other bacteria, Serratia marcescens is a source of hospital-acquired infections, which can happen if a patient's immune system is severely compromised or if the bacterium enters the body with a catheter, respirator or other medical device.

What happens if Serratia marcescens is left untreated?

S. marcescens has been shown to cause a wide range of infectious diseases, including urinary, respiratory, and biliary tract infections, peritonitis, wound infections, and intravenous catheter-related infections, which can also lead to life-threatening bacteremia.

How does one get infected with Serratia marcescens?

Transmission is by direct contact. Droplets of S. marcescens have been found growing on catheters, and in supposedly sterile solutions. Contaminated intravenous pain control fluids were the course of an outbreak of S.

What happens if I touch Serratia marcescens?

If an infected hand touches the eye and natural immunity is unable to fend off Serratia colonization, the result might be conjunctivitis, keratitis or tear duct infections, for example. Once in the bloodstream, Serratia bacteria can cause endocarditis, bacteremia, meningitis, osteomyelitis and arthritis.

Is Serratia serious?

Serratia soft tissue infection is usually very rare and immunocompromised status is the main and usual risk factor. It is usually associated with severe septic shock and high mortality in immunocompromised patients especially renal disease, chemotherapy, immunosuppressants, steroid, and liver disease.

Why is there a blue ring in my toilet?

The cause of the blue ring is elevated levels of copper in your water supply, which causes your water to be more acidic than is usual. The amount of copper won't affect the way the water smells or tastes, and doesn't present a health risk to you or your family.

What causes Serratia marcescens in shower?

The discoloration comes from a biofilm—that is, a bacterial colony—of Serratia marcescens. The airborne bacterial species thrives in moist environments like showers, where it feeds on mineral deposits in soap scum and fatty deposits in soap and shampoo residue.

Why is my shower floor pink?

The “pink mold” you may find in your shower actually isn't mold, but a very common strain of airborne bacteria that's found throughout the world. The bacteria, Serratia marcescens, cause that pink or even red slime you might find in your shower, toilet bowl, or around other water fixtures.

Why pour dish soap in your toilet?

It's pretty simple — just like they do on food particles that are stuck to your dishes in the sink, the combination of hot water and dish soap help to dissolve and break up whatever it may be that is lodged in the toilet causing a clog. This handy tip is great should you find yourself in a pinch.

What causes Serratia marcescens in toilet bowl?

Serratia marcescens love a moist environment but cannot survive in chlorinated water. However, when tap water sits around, like in a toilet bowl, or on grout, or on a shower curtain, the chlorine evaporates and bacteria can take root and multiply, especially if soapy deposits are present which they use as food.

What is the incubation period for Serratia marcescens?

Context in source publication. ... this various incubation period, the results elucidated that 48 hours incubation showed the highest pigment production in S. marcescens and the results were represented in Figure 1.
