Clinical definition:
A systemic disease caused by Salmonella species. Clinical features include fever, anorexia, headache, vomiting, constipation or diarrhoea, abdominal pain or tenderness, cough, delirium / altered level of consciousness, hepatomegaly or splenomegaly. Where available, the organism may be cultured from blood (first week of illness) or stool (after first week), urine or bone marrow. A chronic carrier state may occur with ongoing shedding of the organism in stool which may result in transmission to others via contaminated food or water.

Principles of Stewardship:
- The patient should ideally be isolated with contact precautions maintained until eradication of the organism from the stool is confirmed on 3 stool samples taken 1 week after completion of antibiotic treatment and every 48 hours thereafter to detect chronic carriage and excretion of the organism.
Notes:
- Prolonged therapy (4 – 6 weeks) is recommended in invasive disease, including bone infections, and in immunocompromised patients (including HIV infection)
