*MICs were determined by E-test (AB Biodisk, Solna, Sweden). MICs of chloramphenicol, ampicillin, trimethoprim-sulfamethoxazole, and nalidixic acid were >256 μg/mL, >256 μg/mL, >32 μg/mL, and >256 μg/mL, respectively. FCT, fever clearance time (time from the start of treatment until the body temperature reached 37.5°C and remained at 37.5°C for 48 h); NA:, not available.
†C, confirmed case, i.e., a patient with fever (>38°C) for >3 d and a laboratory-confirmed positive blood culture for Salmonella enterica serotype Typhi; P, probable case, i.e., a patient with fever (>38°C) for >3 d without isolation of S. Typhi.
‡Daily dosages are shown. All fluoroquinolones were given orally. Tosufloxacin is a fluoroquinolone with properties similar to those of levofloxacin.
§Fever relapsed 15 d after completion of treatment. Retreatment with tosufloxacin, 600 mg/d for 14 d, was successful.
