Efficacy of Single-Dose and Conventional Amoxicillin Therapy in Urinary-Tract Infection Localized by the Antibody-Coated Bacteria Technic

Abstract
Urine specimens from 61 women with symptoms of cystitis who were infected with amoxicillin-sensitive organisms were examined by the antibody-coated bacteria assay. Patients with negative assays were randomized to receive either a single 3-g oral dose of amoxicillin or 10 days of amoxicillin, 250 mg, given by mouth four times per day (conventional therapy). Patients with positive assays received conventional therapy.
