Final answer:
The treatment for diarrhea caused by Salmonella is rehydration and supportive therapy. Antibiotics are not typically needed. In severe cases, antibiotics may be used to shorten the duration of infection.
Step-by-step explanation:
The treatment for diarrhea caused by Salmonella is rehydration and supportive therapy. Antibiotics are not typically needed as the illness is usually mild and due to toxin activity. After two days of rehydration therapy, symptoms such as diarrhea, vomiting, and fever typically begin to fade. Stool analysis can be done to check for the presence of Salmonella bacteria. In severe cases, antibiotics like fluoroquinolones, doxycycline, rifaximin, and trimethoprim-sulfamethoxazole (TMP/SMZ) may be used to shorten the duration of infection, but antibiotic resistance is a concern.
