Chlamydia Trachomatis IgM antibodies

Chlamydia is the most common sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. This infection is transmitted during all types of sexual intercourse - vaginal, anal and oral. A mother infected with chlamydia can transmit it to her newborn during childbirth. Anyone who is sexually active can become infected with chlamydia, and the greater the number of sexual partners, the greater the risk of infection. Adolescents and young women are at the highest risk of contracting the infection due to their immature cervix, which is more susceptible to infection.

Primary chlamydial infection is characterized by a predominant IgM response after 2-4 weeks. After an acute C. trachomatis infection, IgM antibodies usually decline within 2 to 6 months.
