Flavimonas oryzihabitans (Kodama et al. 1985) Holmes et al. 1987

Pseudomonas oryzihabitans, also known as Flavimonas orzyhabitans, is a nonfermenting yellow-pigmented, gram-negative, rod-shaped bacterium that can cause septicemia (sepsis), peritonitis, endophthalmitis, and bacteremia. It is an opportunistic pathogen of humans and warm-blooded animals that is commonly found in several environmental sources, from soil to rice paddies. They can be distinguished from other nonfermenters by their negative oxidase reaction and aerobic character. This organism can infect individuals that have major illnesses, including those undergoing surgery or with catheters in their body. Based on the 16S RNA analysis, these bacteria have been placed in the Pseudomonas putida group.

Part of the genus Pseudomonas, originally described in 1894, these bacteria were first identified in urine and gastrointestinal specimens in 1928 by two scientists, E.G. Dresel and O Stickl. At first, this organism was named Chromobacterium typhiflavuum because it closely resembled the bacteria that caused enteric fever. The name change to Pseudomonas oryzihabitans occurred in 1985 after scientist Kentaro Kodama and his team isolated the bacteria from a rice field and found that it had a phenotypic similarity to the pseudomonas organisms. This organism has also been isolated in the hospital environment from a wide variety of sites such as wounds, eyes, skin, ears, and several other places, although they can be found in damp environments as well. As of today, there is little known about the pathogenic qualities of P. oryzihabitans, so possible virulent strains cannot be described or identified absolutely.
