What causes Raoultella Planticola infection?

What causes Raoultella Planticola infection?

Most recently, R. Planticola was discovered in a case of bacteremia-inducted fatal septic shock following a burn injury. Cystitis is the most common type of infection associated with R. Planticola.

Is Raoultella the same as Klebsiella?

Raoultella spp. are Gram-negative, aerobic, non-motile rods. This genus can be distinguished from the genus Klebsiella, in that genus use histamine as the only source of carbon in the medium. Also, Raoultella grow at 4 °C and do not produce gas from lactose at 44.5 °C.

What causes Raoultella Ornithinolytica?

Raoultella ornithinolytica occurs mainly in patients with underlying malignancies or chronic diseases, trauma, nosocomial infection and invasive procedures and is a risk factor for a poor outcome [1, 4, 8, 9, 12].

What is Raoultella Ornithinolytica infection?

Raoultella ornithinolytica is a gram-negative bacterium that lives in an aerophilic environment. Raoultella spp. is an opportunistic pathogen, common in cancer, immunocompromised patients, and most commonly in patients with biliary tract infection, pneumonia, and bacteremia (1–3).

Where is Raoultella found?

Raoultella planticola is an encapsulated, nonmotile, aerobic, gram-negative rod predominantly found in water and soil. Although R planticola is mainly an aquatic and soil bacterium, it has been clinically isolated from human sputum, stool, wound, and urine.

What is Klebsiella Raoultella complex?

Raoultella ornithinolytica is an encapsulated, Gram-negative, nonmotile rod belonging to the Enterobacteriaceae family [6]. It is closely related to Klebsiella spp. and easily misidentified as Klebsiella pneumonia or Klebsiella oxytoca [7].

Where is Klebsiella aerogenes found?

aerogenes is generally found in the human gastrointestinal tract and does not generally cause disease in healthy individuals. It has been found to live in various wastes, hygienic chemicals, and soil.

Where is Raoultella Ornithinolytica found?

R. ornithinolytica has been found in water environments, soil, insects, fish, ticks and termites. This bacterium converts histidine to histamine causing histamine poisoning with cutaneous flushing, better known as the scombroid syndrome associated with fish poisoning.

Is Raoultella Ornithinolytica pathogenic?

ornithinolytica is a Gram-negative aquatic-commensal Enterobacteriaceae [3] and its pathogenic role in community and hospital-acquired infections such as cholangitis, intravascular catheter-related infections, urinary tract infections, skin infections, lower respiratory tract infections, central nervous system …

Is Klebsiella a common UTI?

Conclusion: The gram negative bacteria of Escherichia coli and Klebsiella pneumoniae were the most common uropathogenic bacteria causing UTI.

What is Klebsiella oxytoca Raoultella Ornithinolytica?

Raoultella ornithinolytica is an encapsulated Gram-negative, oxidase-negative, catalase-positive, aerobic, non-motile rod that belongs to the Enterobacteriaceae family. This bacterium was initially classified in the genus Klebsiella as Klebsiella ornithinolytica, until the creation of the genus Raoultella in 2001.

How serious is Klebsiella?

Klebsiella pneumoniae (K. pneumoniae) are normally harmless. The bacteria live in your intestines and feces, but they can be dangerous in other parts of your body. Klebsiella can cause severe infections in your lungs, bladder, brain, liver, eyes, blood, and wounds.

What are the characteristics of the genus Raoultella?

The genus Raoultella is composed of Gram-negative, oxidase-negative, aerobic, nonmotile, capsulated, facultatively anaerobic rods (formerly designated Klebsiella) in the family Enterobacteriaceae. It is named after the French bacteriologist Didier Raoult. Members of genus Raoultella grow at 10 °C consistent…

Why is it called Raoultella planticola?

It is named after the French bacteriologist Didier Raoult. Raoultella planticola on MacConkey agar, showing a positive result (the microorganism has the ability to degrade lactose, which is detected by the pH indicator neutral red).

Is Klebsiella oxytoca the same as Raoultella?

Klebsiella oxytoca is an exception, and a proposal to classify K. oxytoca in a separate, unnamed genus has been made. It consists of species Raoultella electrica, Raoultella ornithinolytica, Raoultella planticola and Raoultella terrigena.

What is the history of Raoultella infections in humans?

The first Raoultella invasive human infection was found in 1984 in a patient with sepsis.2Most reported cases since then have been associated with bacteremia. We present a case of R. Planticola in a patient with UTI, as well as a review of prior reported cases of R. Planticola associated with cystitis.
