Flavimonas oryzihabitansis an uncommon organism with distinctive microbiological and biochemical features that is infrequently isolated from humans. The presence of foreign material, including indwelling intravascular catheters and artificial grafts, or various surgical procedures appear to predispose patients with underlying disease to bacteremic infection withFlavimonas. A gram-negative bacillus,F oryzihabitansis sensitive to most antibiotics except first- and second-generation cephalosporins.F oryzihabitansisolated from blood should be considered pathogenic in patients with indwelling catheters or prosthetic materials.Previously designatedPseudomonas oryzihabitansand also known as Centers for Disease Control (CDC) Group Ve-2,F oryzihabitansis an unusual gram-negative, nonfermenting, oxidase-negative bacillus that is uncommonly associated with serious illness in humans.’ First described by Dresel and Stickl in 1928 and initially assigned the nameBacterium typhiflavumbecause of its similarity to the typhoid bacillus, the organism has been isolated from a variety of human sources, including blood, wounds, and abscesses, and (in mixed cultures) from sputum, urine, and cervical cultures.
