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.

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.

What is the natural habitat of Serratia marcescens?

Serratia marcescens is found in fresh and stagnant water or saline, in the soil, and in plants, insects, and animals including the human species. It has known pathogenicity for non-plant life made even more potent through its characteristic multi-antibiotic resistance.

What diseases or problems does Serratia marcescens cause?

Well-documented infections caused by S. marcescens include pneumonia, urinary tract infection, bacteremia, biliary tract infection, wound infection, meningitis, and endocarditis. Rarely does it present as cellulitis and necrotizing fasciitis (NF), resulting in severe sepsis and multiorgan failure.

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 do we get Serratia infection?

The major factors that are involved in the development of the Serratia infection include contamination of the respiratory equipment and poor catheterization techniques. Most of the outbreaks have been reported from the paediatrics ward.

How did I get Serratia marcescens?

The bacteria will grow in any moist location where phosphorous containing materials or fatty substances accumulate. Sources of these substances include soap residues in bathing areas, feces in toilets, and soap and food residues in pet water dishes.

Is Serratia marcescens serious?

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.

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.

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.

What temperature does Serratia marcescens grow?

Perhaps it is noteworthy that the optimal growth range for Serratia marcescens is 25-37C, and it is above this temperature range that pigment production ceases. It is possible that the loss of pigment is associated with mild temperature stress.

Is Serratia marcescens killed by heat?

Cultures of the strains killed at the initial temperature were subjected to decreasing degrees of heat until they survived. Of the 31 strains 11 remained viable after 60°C. for 15 minutes; of these, one was killed only at 68°C. in 15 minutes and at 65 ° for 30 minutes.

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.

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.

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.

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

Bleach. Bleach can be used for mold and Serratia marcescens. If you opt for this course of action, make sure you have good ventilation in the room, and never mix bleach with vinegar or ammonia as it can cause toxic fumes.

Why is the water in my toilet pink?

What is the pink deposit that is sometimes seen in toilets and around sinks and bathtubs? The pink colour is due to a pigment secreted by a species of bacteria known as Serratia marcescens, found naturally in soil, air and water.

Why does my toilet bowl get a pink ring?

In most cases a pink residue is likely a result of airborne bacteria which produce a pinkish or dark gray film on moist surfaces. This film is usually found as a ring that accumulates at the water line in the toilet bowl or around showerheads, shower doors or curtains, sink drains, bathtubs, tiles and grout.

What happens if you get Serratia marcescens?

S. marcescens bacteria is known to cause a variety of different 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.

Is Serratia marcescens curable?

Abstract. An old man receiving peritoneal dialysis was diagnosed with Serratia marcescens peritonitis, a rare case with poor prognosis. Powerful antibiotics based on culture results and enough duration cured the case successfully despite its high virulence.

Can Serratia marcescens cause skin infection?

The incidence of skin infections caused by Serratia marcescens is extremely low and such infections are typically observed in immunocompromised patients. The clinical manifestations of these infections include cellulitis, abscesses, fluctuant nodules, or granulomatous lesions.

Why does my water turn my shower 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.

How common is Serratia?

Serratia Species

The estimated incidence of Serratia infections in CGD patients is up to 0.98 cases per 100 patient-years, with a recurrence rate of 18%. Lymphadenitis and skin abscesses are the most common infections (44%), followed by pulmonary infections (36%) and osteomyelitis (8%).

Is Serratia 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.

Can Serratia cause UTI?

Approximately 30-50% of patients with Serratia urinary tract infections are asymptomatic. 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.
