New single-dose antibiotic effectively treats uncomplicated gonorrhea infections

A phase 2 clinical trial led by Stephanie N. Taylor, MD, Professor of Medicine and Microbiology in the Section of Infectious Diseases at LSU Health New Orleans School of Medicine, has found that a new antibiotic effectively treats uncomplicated urogenital and rectal gonorrhea infections in a single oral dose.
