Raoultella ornithinolyticaRANK: SpeciesTAXONOMY: Bacteria -> Proteobacteria -> Gammaproteobacteria -> Enterobacteriales -> Enterobacteriaceae -> Raoultella -> Raoultella ornithinolytica OVERVIEW: Raoultella ornithinolytica is a gram-negative encapsulated aerobic bacillus belonging to family Enterobacteriaceae that is found in aquatic environments, fish, and insects. The most distinctive feature of this bacterium is its ability to convert histidine to histamine in scombroid fish. Consequently, infection with this microorganism causes redness and flushing on the skin. Histamine fish poisoning is caused by histamine-producing bacteria (HPB).R ornithinolytica is a histamine-producing bacterium that subsequently causes fish poisoning. Human infections related to R ornithinolytica are exceedingly rare. Here, we report R ornithinolytica isolated from the wound of diabetic foot in a patient with predialytic chronic kidney disease (CKD). |
