Salmonellosis: Infection with bacteria belonging to the genus Salmonella. Salmonellosis is a common cause of food poisoning.

The symptoms of salmonellosis usually begin within 12 to 24 hours of exposure to the bacteria and include stomach cramps, diarrhea, fever, and sometimes vomiting.

The diagnosis can be confirmed by examination of a stool sample for the Salmonella bacteria. Most people exposed to Salmonella feel fine within a few days and do not require treatment other than extra fluids. Some people need antibiotics. And a few need hospitalization.

Salmonellosis is particularly dangerous in people with AIDS and other immunodeficiency diseases and in people with sickle cell anemia.
