What is Raoultella Planticola infection?
What is Raoultella Planticola infection?
Raoultella planticola is a gram-negative, aerobic, nonmotile mostly found in environments with high prevalence in soil and water. This organism is a very rare human pathogen as only 29 cases of Raoultella planticola–related infections have been reported until 2017, with only 7 cases in the United States.
What causes Raoultella Planticola?
The cause of R. Planticola infection cystitis is not well understood. According to a review of the literature, 4 out of 6 cases (Table 1) were attributed to immunosuppression.
How is Raoultella 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].
Is Raoultella Ornithinolytica pathogenic?
Raoultella ornithinolytica (formerly Klebsiella ornithinolytica) is a Gram-negative bacillus that belongs to the Enterobacteriaceae family [1]. Its role in the pathogenesis of human infections has recently been recognized [2].
What is Raoultella Ornithinolytica urine?
Raoultella ornithinolytica is an uncommon human pathogen, with only ten cases having been previously reported. This organism can be misdiagnosed as Klebsiella pneumoniae or Klebsiella oxytoca, and its expression of β-lactamase confers resistance to ampicillin and other commonly used antibiotics.
What antibiotics cover Klebsiella?
Klebsiella is best treated with third- and fourth-generation cephalosporins, quinolones, or carbapenems.
How do you get Raoultella Ornithinolytica?
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.
What percentage of humans are colonized with R Planticola?
Specifically, R planticola has become an emerging pathogen in humans. It is estimated that 9% to 18% of human populations are colonized with R planticola. Raoultella species are known to colonize the gastrointestinal and upper respiratory tracts in humans.
Is Raoultella Ornithinolytica indole positive?
While R. ornithinolytica is indole-positive, R. planticola is indole variable. Moreover, previous studies have reported cases of incorrect identification of R.
Where is Raoultella Ornithinolytica found?
Who is susceptible to Klebsiella?
The susceptibility is significantly lower among isolates from elderly compared with those from adult patients. (P < 0.05). The susceptibility is significantly lower among isolates from elderly compared with those from pediatric patients.
