Citrobacter - Enterobacteriaceae

CITROBACTER

The genus Citrobacter, although biochemically and serologically similar to Salmonella, is an uncommon cause of opportunistic infection; it does not cause enterocolitis or enteric fever. Like many other Enterobacteriaceae, Citrobacter strains may be present in the nor-mal intestinal flora and cause opportunistic infections. Despite reports of association with diarrheal disease, present evidence does not indicate that Citrobacter should be consid-ered an enteric pathogen. C. freundii has been associated with neonatal meningitis and brain abscess.
