Chlamydia trachomatis is a type of bacteria that causes the sexually transmitted infection known as chlamydia. It primarily affects the genital tract but can also infect the throat and eyes. Many people infected with Chlamydia trachomatis do not show symptoms, which can lead to complications if left untreated. Diagnosis is typically made through laboratory tests, and treatment usually involves antibiotics. If detected early, chlamydia can be easily cured, reducing the risk of serious health issues such as infertility or pelvic inflammatory disease. Regular screening is recommended for sexually active individuals to prevent the spread of this infection.
