liquefaciens causing community-acquired infections include peritonitis associated with continuous ambulatory peritoneal dialysis [12], pustulosis and costochondritis in heroin addicts [13], fistulous pyoderma [14], septic arthritis [15] and ocular infections resulting from contamination of contact lens cases [16].

Keeping this in view, where is Serratia Liquefaciens found?

Serratia, Edwardsiella and Morganella belong to Enterobacteriaceae group of gram-negative bacteria. They are facultative anaerobic. They are non-spore forming enteric bacilli (rod shaped). Serratia is found in soil, water, plants, and human intestine.

Additionally, what are the symptoms of Serratia marcescens?

Urinary tract infection
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.

What is Serratia used for?

marcescens is commonly involved in hospital-acquired infections (HAIs), particularly catheter-associated bacteremia, urinary tract infections, and wound infections, and is responsible for 1.4% of HAI cases in the United States.

Serratia marcescens
Species: S. marcescens
Binomial name
Serratia marcescens Bizio 1823

What antibiotics cover 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 is Serratia Liquefaciens spread?

Infections caused by S. marcescens may begin with exogenous contamination and spread within or among hospitals on the hands of personnel. The most common site of infection is the urinary tract, but the organism is frequently isolated from the respiratory tract and from wounds.

How do you get Serratia?

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.

What is the best treatment for Serratia marcescens bacteria?

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 airborne?

The most likely cause is an airborne bacteria called Serratia Marcescens. This bacteria is common and generally grows in damp conditions such as those found in bathrooms and kitchens. Serratia is an airborne bacteria and can not survive in your chlorinated water supply.

What is serratia sepsis?

Sepsis or bacteremia
The main risk factor for Serratia sepsis/bacteremia is hospitalization. A multistate outbreak of S marcescens bloodstream infection was linked to contaminated intravenous magnesium sulfate distributed in the United States by a compounding pharmacy.

What is Serratia infection?

Specialty. Infectious disease. Serratia infection refers to a disease caused by a species in the genus Serratia. The species involved is usually Serratia marcescens. It can cause nosocomial infections.

Why is Serratia marcescens used for science experiments?

This common microbe is found in soil, water, on plants and in animals. Because this microbe is so common, because of its bright red color and because it used to be considered benign, scientists and teachers frequently used it in experiments to track microbes and to demonstrate the importance of hand washing.

Where is Pseudomonas found?

Epidemiology. Pseudomonas aeruginosa commonly inhabits soil, water, and vegetation. It is found in the skin of some healthy persons and has been isolated from the throat (5 percent) and stool (3 percent) of nonhospitalized patients.

Is Serratia found in water?

Serratia bacteria are common inhabitants of our environment and can be found in many places, including human and animal feces, dust, soil, and in surface waters. Serratia will not survive in chlorinated drinking water. Serratia marcescens is not known to cause any waterborne diseases.

Is Serratia marcescens harmful to humans?

Today, Serratia marcescens is considered a harmful human pathogen which has been known to cause urinary tract infections, wound infections, and pneumonia. Serratia is normally not harmful to healthy people but it is what is known as an opportunistic pathogen. Given the opportunity, Serratia can spell trouble.

What are nosocomial infections?

'Nosocomial' or 'healthcare associated infections' (HCAI) appear in a patient under medical care in the hospital or other health care facility which was absent at the time of admission. These infections can occur during healthcare delivery for other diseases and even after the discharge of the patients.

Is s Liquefaciens Gram positive or negative?

Serratia liquefaciens has a straight rod structure that is Gram negative. Gram negative organisms have a thinner layer of peptidoglycan surrounded by an inner and outer membrane. Serratia species are usually motile and have peritrichous flagella.

Does Serratia Liquefaciens ferment lactose?

Of the many species in the genus Serratia, Serratia marcescens is the one most commonly isolated from human infections and Serratia liquefaciens is occasionally grown. Serratia strains are motile, rarely ferment lactose, and produce an extracellular DNase. Thus, most infections are acquired exogenously.

What is the morphology of Serratia marcescens?

Gram Stain: Gram-negative.
Morphology: Straight rods with rounded ends.
Size: 0.5-0.8 micrometers by 0.9-2.0 micrometers.
Motility: Usually motile by peritrichous flagella.
Capsules: None.

Is Enterobacter aerogenes Gram negative?

Klebsiella aerogenes, previously known as Enterobacter aerogenes, is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium. aerogenes is generally found in the human gastrointestinal tract and does not generally cause disease in healthy individuals.
