Description Bacterium that causes chlamydial sexually transmitted infections, trachoma, and lymphogranuloma venereum
Structure Chlamydia trachomatis is an obligate intracellular Gram-negative bacterium belonging to the family Chlamydiaceae. The organism possesses a unique biphasic developmental cycle consisting of the infectious elementary body (EB) and the metabolically active reticulate body (RB). Elementary bodies are specialized for extracellular survival and host cell infection, while reticulate bodies replicate within membrane-bound intracellular inclusions inside host epithelial cells. Chlamydia trachomatis is a strictly human pathogen and is one of the most common bacterial causes of sexually transmitted infections worldwide. Different serovars are associated with distinct diseases, including urogenital infections, trachoma, and lymphogranuloma venereum (LGV). Because the organism relies extensively on host cellular machinery for replication, it cannot be propagated on conventional bacteriological culture media.
Diagnosis The diagnosis of Chlamydia trachomatis infection is performed primarily through nucleic acid amplification tests (NAATs), including polymerase chain reaction (PCR)-based assays, which are considered the gold standard due to their high sensitivity and specificity. Testing can be performed using urine specimens, vaginal swabs, cervical swabs, urethral swabs, rectal swabs, or other appropriate clinical samples. Serological assays, including ELISA-based methods, may be useful for epidemiological studies or selected clinical situations but are generally less useful for diagnosing uncomplicated genital infections. Culture techniques are rarely used in routine clinical practice because of technical complexity. Early and accurate diagnosis is essential because many infections are asymptomatic and untreated disease can result in significant long-term complications.
Symptoms Chlamydia trachomatis infection is frequently asymptomatic, particularly in women, which contributes to ongoing transmission. Symptomatic urogenital infection may present with dysuria, urethral discharge, cervicitis, abnormal vaginal discharge, pelvic pain, postcoital bleeding, or testicular pain. Untreated infection can ascend to cause pelvic inflammatory disease (PID), ectopic pregnancy, infertility, and chronic pelvic pain. Certain serovars cause lymphogranuloma venereum, characterized by genital ulcers followed by painful lymphadenopathy and proctocolitis. Ocular infection can result in trachoma, a chronic inflammatory eye disease that remains a leading infectious cause of blindness worldwide. Neonatal infection acquired during childbirth may cause conjunctivitis or pneumonia. Prompt diagnosis and treatment are important to prevent complications and reduce transmission.
