Antibiotic therapy for typhoid fever.

A retrospective clinical study was conducted to evaluate the efficacies of various kinds of antibiotics on 804 patients with typhoid fever. Of 16 regimens studied, ofloxacin and enoxacin achieved 100 cure rates without relapse or carriage of Salmonella typhi within 3 months. Their good safety profiles and relatively lower costs were very cost-effective for treatment of typhoid fever, and they can be recommended as the first-line choices for routine management of this disease. In addition, our results suggested that ceftriaxone treatment of typhoid fever should be given at higher dose: not less than 3 g once daily, or over a longer period, to reduce the incidence of relapse.
