C. koseri can sometimes be an opportunistic pathogen, particularly in immunocompromised patients in hospitals or in infants. It causes wound infections, septicemia, and neonatal meningitis.
Citrobacter koseri (formerly C. diversus) can be isolated from water, sewage, soils, and food, as well as from the feces of man and other animals, where they may be considered normal flora.
