Klebsiella oxytoca on agar plate. Klebsiella oxytoca is a Gram-negative, rod-shaped bacterium that is closely related to K. pneumoniae, from which it is distinguished by being indole-positive; it also has slightly different growth characteristics in that it is able to grow on melezitose, but not 3-hydroxybutyrate.
Health authorities identified 20 cases of Klebsiella oxytoca, of which 15 were confirmed, four were classified as probable, and one was ruled out. Of the 20 cases, 13 children died and seven ...
Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule. [3] Klebsiella is named after German-Swiss microbiologist Edwin Klebs (1834–1913). Carl Friedlander described Klebsiella bacillus which is why it was termed Friedlander bacillus for many years.
The genus Klebsiella was named after the German microbiologist Edwin Klebs (1834–1913). [citation needed] It is also known as Friedlander's bacillum in honor of Carl Friedländer, a German pathologist, who proposed that this bacterium was the etiological factor for the pneumonia seen especially in immunocompromised individuals such as people with chronic diseases or alcoholics.
Members of genus Raoultella grow at 10 °C consistent with their recovery from plants, soil, and water, whereas members of Klebsiella do not grow at 10 °C [4] and are mainly recovered from mammals' mucosae. Klebsiella oxytoca is an exception, and a proposal to classify K. oxytoca in a separate, unnamed genus has been made. [5]
Klebsiella michiganensis is a species of bacteria in the genus Klebsiella and is one of the nine species in the Klebsiella oxytoca complex. [1] It is closely related to the species K. oxytoca except K. michiganensis is negative in the pectin degradation test and negative by PCR for polygalacturonase gene pehX. [1]
Tilivalline is a nonribosomal enterotoxin and was the first naturally occurring pyrrolobenzodiazepine (PBD) to be associated with disease in the human intestine. [1] Previous work has shown that PBD tilivalline produced by Klebsiella oxytoca was linked to the pathogenesis of colitis in animal model of antibiotic-associated hemorrhagic colitis (AAHC). [2]
There are at least 19 distinct inhibitor-resistant TEM β-lactamases. Inhibitor-resistant TEM β-lactamases have been found mainly in clinical isolates of E. coli, but also some strains of K. pneumoniae, Klebsiella oxytoca, P. mirabilis, and Citrobacter freundii.
