Flavimonas oryzihabitans

Flavimonas oryzihabitans, formerly known as Pseudomonas oryzihabitans, is a Gram-negative, oxidase-negative, indole-positive bacterium. It is a non-fermentative, yellow-pigmented, aerobic bacterium that is commonly found in the environment, particularly in water and soil.

Taxonomy

The bacterium was first isolated from the roots of a rice plant and was initially classified as Pseudomonas oryzihabitans in 1983. However, it was later reclassified to the genus Flavimonas in 1990 based on phylogenetic studies.

Clinical significance

Flavimonas oryzihabitans is an opportunistic pathogen, meaning it can cause disease in individuals with compromised immune systems. It has been associated with a variety of infections, including bacteremia, sepsis, peritonitis, endophthalmitis, and meningitis. The bacterium is also known to cause infections in patients with indwelling medical devices, such as catheters and prosthetic devices.

Treatment

Treatment of Flavimonas oryzihabitans infections typically involves the use of antibiotics. However, the bacterium has been found to be resistant to a number of commonly used antibiotics, including ampicillin, cephalosporins, and aminoglycosides. Therefore, susceptibility testing is often necessary to determine the most effective treatment.
