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.
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.
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]
On carbohydrate-rich media, Klebsiella colonies appear greyish-white in colour with a mucosal outer surface. [6] The media used for selecting for Klebsiella species in a mixed sample is an agar including ornithine, raffinose, and Koser citrate, where members of this genus will form yellow, wet-looking colonies.
