text: Salmonella typhi is similar to other salmonellae in that it is a gram-negative, flagellate, nonencapsulated, nonsporulating, facultative anaerobic bacillus that ferments glucose, reduces nitrate to nitrite, and synthesizes peritrichous flagella when motile. \n\nBeing such, you can use chloramphenicol, ampicillin (or any penicillin), Trimethoprim/sulfamethoxazole, Ciprofloxacin (or any quinolone), a 3rd generation cephalosporin, or azithromycin.
