Where is Serratia normally found?

Serratia marcescens, which can cause nosocomial 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.

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.

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%).

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.

Is Serratia spread in water?

You can find Serratia marcescens abundantly on Earth, including in water or dirt. These microbes love wet surfaces, and they go crazy if that damp spot also contains phosphorus or fatty residue such as soap or shampoo.

Serratia Biochemical test results

How do I get rid of Serratia marcescens in my house?

Once established, the organism usually cannot be eliminated entirely. However, periodic and thorough cleaning of the surfaces where the pink slime occurs, followed by disinfection with chlorine bleach, appears to be the best way to control it.

Is Serratia 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.

Can Serratia be cured?

Serratia marcescens is a rare agent causing peritonitis, and few cases of Serratia marcescens peritonitis in previous reports were successfully cured without removing the peritoneal catheter.

What antibiotics treat Serratia?

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.

How does Serratia marcescens enter the body?

S. marcescens infections are known to be transmitted through hand-to-hand contact by medical personnel.

Can you be colonized with Serratia?

Colonization by Serratia spp. was associated with yearly age at admission, long ICU stay and high mortality. Both the respiratory and digestive tracts were frequently colonized.

Is Serratia a gut bacteria?

A Gut Symbiotic Bacterium Serratia marcescens Renders Mosquito Resistance to Plasmodium Infection Through Activation of Mosquito Immune Responses. The malaria development in the mosquito midgut is a complex process that results in considerable parasite losses.

Can Serratia be a contaminant?

Serratia marcescens is a common bacterial contaminant, and its resilient nature coupled with genetic promiscuity imbue this environmental bacterium with resistance to disinfectants and antibiotics enhancing bacterial virulence.

Can Serratia cause UTI?

There have been only a few reported human cases of infections caused by Serratia rubidae in literature. Among these sparse cases there is only one reported case of urinary tract infection (UTI) due to S. rubidae in literature. The organism is known to produce a red pigment known as prodigiosin.

What disinfectant kills Serratia marcescens?

Pseudomonas aeruginosa was killed in 10 seconds by all concentrations of ethanol from 30% to 100% (v/v), and Serratia marcescens, E, coli and Salmonella typhosa were killed in 10 seconds by all concentrations of ethanol from 40% to 100%.

How is Serratia diagnosed?

Serratia is diagnosed with patient history and physical examination.

What symptoms does Serratia marcescens cause?

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.

Is there a blood test for Serratia marcescens?

marcescens (in blood) has been reported. In this study, we developed a specific real-time PCR assay for the detection of S. marcescens in blood and indeed diagnosed septicaemia from the results. We also evaluated the assay in a mouse infection model, and demonstrated the simultaneous detection of S.

Does Serratia marcescens smell?

It produces a fishy-urinary odor (trimethylalamine). It can be isolated from food, soil, water, plants, insects, and sewage. It is a potential pathogen for insects, animals, and humans and is an important cause of nosocomial (hospital-acquired) infections in humans.

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.

How do you get Serratia in lungs?

It can naturally occur in soil and water as well as in the intestine. It can often involve the lungs as a nosocomial (hospital-acquired) infection. Serratia species may sometimes harbor multidrug-resistance mechanisms that can complicate treatment.

Can Serratia marcescens go away on its own?

Although extremely rare, it can also cause pneumonia and meningitis. Once s. marcescens has established itself on a surface, completely eliminating it can be very difficult. Total eradication of the bacteria can be only accomplished with a bleach-based disinfectant or cleaner.

How do I get rid of Serratia marcescens in my shower?

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.

What is the incubation period for Serratia marcescens?

growth Curve of Serratia marcescens growth during the 24-hour incubation period on culture treated with rice straw substrate variations. Indonesia is a country with vast agricultural land, especially rice fields.

Is Serratia marcescens a mold?

That nasty substance is called Serratia marcescens, a microorganism commonly referred to as pink mold. Even though it's been labeled a “mold,” this substance is actually a bacteria, not a fungus. These little guys thrive in warm, wet environments and feed off fatty substances (like soap residue for instance).
