Overview
Pathophysiology
Lymphogranuloma venereum (LGV) is a chronic (long-term) infection of the lymphatic system caused by three different types of the bacteria Chlamydia trachomatis. The bacteria spread through sexual contact. The infection is caused by a different bacteria than that which causes genital chlamydia.
Transmission
- Lyphogranuloma venereum (LGV) may develop after transmission of servars L1, L2, or L3 of the bacterium Chlamydia trachomatis.
- C. trachomatis can be transmitted through vaginal, anal, or oral sexual contact.[1]
- C. trachomatis is an obligate intracellular pathogen.[2]
Pathogenesis
- Inoculation and replication of C. trachomatis serovars L1, L2, or L3 depends on alternation between two forms of the bacterium: the infectious elementary body (EB) and noninfectious, replicating reticulate body (RB).[3]
- The EB form is responsible for inoculation with C. trachomatis.
- The C. trachomatis EB enters the body through skin abrasions, microabrasions incurred during sexual intercourse or by crossing epithelial cells of mucous membranes.[4]
- C. trachomatis produces the extracellular ligand major outer membrane protein (MOMP), which is presumed to bind with heparan sulfate host epithelial cells.[3]
- Once bound, the EB is engulfed by receptor-mediated endocytosis creating vacuoles termed "inclusions".[5]
