Klebsiella oxytoca
Klebsiella oxytoca is a Gram-negative, rod-shaped bacterium that is closely related to K. pneumoniae, from which it is distinguished through its production of indole. This species was first described in 1886 when it was isolated from sour milk and named Bacillus oxytocus perniciosus (from Greek oxus 'sour' + -tokos 'producing').

Description
K. oxytoca also has slightly different growth characteristics in that it is able to grow on melezitose, but not 3-hydroxybutyrate. Klebsiella oxytoca is characterized by negative methyl red, positive VP, positive citrate, urea and TSI gas production, is AA, and negative for TSI sulfide, DNAse, growth on sulfide-indole motility medium and the phenylalanine deaminase test. It is a diazotroph, able to colonise plant hosts and fix atmospheric nitrogen into a form which the plant can use. Association of K. oxytoca with the barley rhizosphere during an entire vegetative period has been demonstrated. The bacteria adhere strongly to root hairs, and less strongly to the surface of the zone of elongation and root cap mucilage. Like other enterobacteria, it is capable of acquiring antibiotic resistance, and isolates have been shown to produce extended-spectrum beta-lactamases as well as carbapenemases.

What it does
Houseflies (Musca domestica) have a mutualistic relationship with the bacterium K. oxytoca. This bacterium can live on the surface of the housefly eggs and has a deterrent effect on the fungi growing in manure, thus benefiting the fly larvae which are competing with the fungi for nutrients.
