Citrobacter is a genus of Gram-negative, aerobic, rod-shaped[2] coliform bacteria of the Enterobacteriaceae family. Citrobacter spp. cause opportunistic infections (including urinary tract infections, gastroenteritis, and bacteremia).[2] MicrobiologyMicrobial biochemistryThe species C. amalonaticus, C. koseri, and C. freundii can use citrate as a sole carbon source. Citrobacter species are differentiated by their ability to convert tryptophan to indole (C. koseri is the only Citrobacter species to be commonly indole-positive), ferment lactose (C. koseri is a lactose fermentor), and use malonate.[3] Citrobacter shows the ability to accumulate uranium by building phosphate complexes.[4] Environmental microbiologyThese bacteria can be found almost everywhere in soil, water, wastewater, etc. They can also be found in the human intestine.[5][6] Clinical significanceCitrobacter are found in the intestinal tract of humans and transmission usually occurs through human to human contact.[7] They are considered opportunistic nosocomial pathogens, typically associated with urinary tract infections and infant meningitis and sepsis.[8] Antimicrobial resistanceCitrobacter freundii strains have inducible ampC genes encoding resistance to ampicillin and first-generation cephalosporins.[9] In addition, isolates of Citrobacter may be resistant to many other antibiotics as a result of plasmid-encoded resistance genes.[8] References
