a genus of gram-negative, facultatively anaerobic, motile, rod-shaped bacteria, which have been associated with diarrhea and secondary infections in debilitated persons, occasionally causing primary septicemia. Species include C. amalona´ticus and C. freun´dii, two opportunistic pathogens; and C. diver´�sus, an occasional cause of neonatal meningitis.
A genus of motile bacteria (family Enterobacteriaceae) containing gram-negative rods that 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 Citrobacter freundii.
Citrobacter/Cit·ro·bac·ter/ (sit´ro-bak″ter) a genus of gram-negative, facultatively anaerobic, rod-shaped bacteria of the family Enterobacteriaceae. C. amalona´ticus, C. diver´sus, and C. freun´dii have been associated with nosocomial infection, particularly in debilitated patients, and in neonates have caused meningitis and brain abscess.
a genus of gram-negative, lactose fermenting rods, members of the Enterobacteriaceae. Found in water, feces and urine, and not considered to be animal pathogens.
have been identified as the cause of septicemic cutaneous ulcerative disease of turtles. The disease is characterized by cutaneous hemorrhage and ulceration, loss of claws and digits, flaccidity and paralysis.
