Citrobacter species

Citrobacter, courtesy CDC

Citrobacter species are rod-shaped bacteria that are found in the environment and also in the human intestinal tract. Citrobacter species have been associated with diarrhoea and secondary infections in debilitated persons, infections of the urinary tract, and infant meningitis. 

They also occasionally cause severe bloodstream infections (bacteraemia).  C. freundii is the most commonly isolated species.
