Molecular Epidemiology of Chlamydia Trachomatis Infection in the Genitourinary Tract

The genitourinary Chlamydia trachomatis infection is a crucial part of sexually transmitted disease worldwide. In recent years, the incidence rate has increased dramatically, and the proportion of asymptomatic infections is particularly large. Therefore the burden for preventing and controlling its epidemic is severe. With the development of laboratory technology and genomics, the understanding on the molecular epidemiology of genital Chlamydia trachomatis is gradually clearer than ever, and the monitor on its epidemic trends and strain variation is becoming more effective.■
