Are there particular antibiotics used to treat salmonellosis?

Yes, but seldom... Salmonella gastroenteritis, in general, is a self-limiting condition and does not require antimicrobial therapy. Exceptions are young infants under 6 months, salmonella osteomyelitis, and food handlers. Typhoid fever, a rare condition in us, certainly requires an appropriate antibiotic treatment.
Cipro (ciprofloxacin) Cipro (ciprofloxacin) is given but salmonella usually has a short course and hydration is the most important part of treatment.
