Enterobacter species

Enterobacter species are rod-shaped bacteria that are found in the environment and also in the human intestinal tract.  

Some species are pathogenic, the most common being E. cloacae and E. aerogenes, which can cause opportunistic infections in immunocompromised patients.  The urinary and respiratory tracts are the most common sites of infection with Enterobacter species, but bloodstream infections may occur on occasion.  

E. sakazakii has been associated with infection in neonates linked to contamination of infant milk formula feeds.
