Epidemiology of Anorectal Chlamydial and Gonococcal Infections Among Men Having Sex With Men in Seattle

Abstract

Prevalences of anorectal chlamydial infection and gonorrhea among MSM in Seattle have increased dramatically over the past 3 years. Serovar and auxotype analyses indicate these increases are not clonal but are due to the spread of unique distributions of strains that differ from those causing urogenital infections in the same community.
