Citrobacter

A genus of motile bacteria (family Enterobacteriaceae) containing Gram-negative rods which use citrate as a source of carbon; the motile cells are peritrichous. Fermentation of lactose by these organisms is delayed or absent; they produce trimethylene glycol from glycerol. The type species is C. freundii.
- C. amalonatica a bacterial species found in feces, soil, water, and sewage; isolated from clinical specimens as an opportunistic pathogen. SYN: Levinea amalonatica.
- C. diversus a bacterial species found in feces, soil, water, sewage, and food; isolated from urine, throat, nose, sputum, and wounds; reported in cases of neonatal meningitis where it frequently is severe, resulting in brain abscess formation. SYN: C. koseri, Levinea diversus, Levinea malonatica.
- C. freundii a bacterial species found in water, feces, and urine; it is an inhabitant of the normal intestine, but it may occur in alimentary infections and in infections of the urinary tract, gallbladder, middle ear, and meninges; it is the type species of the genus C..
