What is Klebsiella oxytoca Raoultella Ornithinolytica?
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].
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).
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 …
What causes Raoultella Ornithinolytica?
Raoultella ornithinolytica (formerly Klebsiella ornithinolytica) is a gram-negative aerobic bacillus in the family Enterobacteriaceae. This species has been related to histamine-producing bacteria causing subsequent fish poisoning (5). R. ornithinolytica has also been isolated from dentin of infected root canals (8).
How is Raoultella Ornithinolytica treated?
The consensus recommendation is that a Raoultella ornithinolytica infection should be treated with antibiotics e.g. amoxicillin plus clavulanic acid for 10-14 days [6].
What diseases does Klebsiella oxytoca cause?
Klebsiella are opportunistic pathogens that cause severe diseases in hospital setting. This organism causes pneumonia, urinary tract infection, soft tissue infection and septicaemia, which often leads to septic shock.
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.
How is Raoultella Planticola treated?
Planticola consists of a single course of antibiotics. In each case antibiotics have led to full recovery and resolution of symptoms. Antibiotics that have successfully treated R. Planticola UTI’s include Ciprofloxacin, Ceftriaxone, Cefotaxime, Nitrofurantoin, Cephalexin, Cefpodoxime, and Ampicillin/Sulbactam.
What antibiotics treat Raoultella Planticola?
Antibiotics that have successfully treated R. Planticola UTI’s include Ciprofloxacin, Ceftriaxone, Cefotaxime, Nitrofurantoin, Cephalexin, Cefpodoxime, and Ampicillin/Sulbactam. In our case report, we chose to treat with Nitrofurantoin, given its high sensitivity to most uropathogens (Table 2). R.
Is Raoultella ornithinolytica a human infection?
Abstract Background: Raoultella ornithinolytica is known to inhabit aquatic environments. The clinical features and outcomes of human infections caused by R. ornithinolytica have been reported for only a limited number of cases.
Is Raoultella planticola pathogenic?
Raoultella spp. are opportunistic bacteria, which usually cause infections of the biliary tract, pneumonia and bacteraemia in oncologic and with lower immunity patients. Raoultella planticola and Raoultella ornithinolytica are the most frequently encountered human pathogens among the genus Raoultella.
Is Klebsiella ornithinolytica antimicrobial resistant?
Physicians should be aware of the high rates of antimicrobial resistance of R. ornithinolytica isolates so that immediate broad-spectrum antibiotic treatment can be established before accurate microbiological results are obtained. Keywords: Bacteria; Human; Infection; Klebsiella ornithinolytica; Raoultella ornithinolytica.
What is Enterobacter ornithinolytica?
R. ornithinolytica is an underreported, emerging hospital-acquired infection and is particularly associated with invasive procedures. R. ornithinolytica should never be considered simply a saprophytic bacterium that occasionally contaminates bronchial lavage or other deep respiratory samples or surgical sites.
