Prevalence and persistence of<i>Chlamydia trachomatis</i>-specific antibodies after occasional and recurrent infections

Abstract

Approximately one-third of women with single notification of chlamydia infection remain seropositive 3-10 years after the initial infection. The concentration of antibodies remained stable during the follow-up. Recurrent infection boosted the humoral immune response, but reinfection occurred despite the presence of pre-existing antibodies.
