Chlamydia trachomatis

When it comes to Chlamydia trachomatis, the first thing that comes to mind is trachoma. This is the most common Chlamydia trachomatis we see. Once you have trachoma, you will often shed tears. The most obvious feature is the small red bumps the size of sand grains in the inner eyelids, which make the patient's eyes very uncomfortable. Trachoma is highly contagious and is usually transmitted through contact. Therefore, trachoma patients must pay attention to the details of their lives and not spread trachoma to people around them.

Chlamydia trachomatis not only causes trachoma, but also causes genitourinary infections and sexually transmitted diseases. There is currently no good prevention method for Chlamydia trachomatis, and vaccines are under research. Maintaining good personal hygiene and being careful not to have casual sexual intercourse can effectively reduce Chlamydia trachomatis infection. The following are some diseases that are easily caused.

Trachoma: Caused by Chlamydia trachomatis biovar A, B, Ba, and C serotypes. It is mainly transmitted through direct or indirect contact, that is, eye-to-eye or eye-hand-to-eye. When Chlamydia trachomatis infects conjunctival epithelial cells, it proliferates in them and forms scattered, cap-shaped, mulberry-shaped or filling-shaped inclusion bodies in the cytoplasm. The disease develops slowly, with acute or subacute inflammation of the eyelid conjunctiva appearing in the early stages, manifested by symptoms and signs such as tearing, mucopurulent secretions, and conjunctival congestion. In the later stage, the disease becomes chronic, with conjunctival scarring, entropion, trichiasis, and corneal damage caused by corneal pannus, which affects vision and eventually leads to blindness. According to statistics, trachoma is the leading cause of blindness. In 1956, Chinese scholar Tang Feifan and others successfully isolated Chlamydia trachomatis for the first time in the world using the chicken embryo yolk sac inoculation method, thus promoting research on the related organisms. Inclusion body peritonitis: caused by the trachoma organism variant DK serotype. Including both infants and adults. The former is caused by infection of the infant's birth canal, which causes acute purulent conjunctivitis (inclusion body pus leakage into the eye), does not invade the cornea, and can heal itself. Adult infection can occur through sexual contact, hand-to-eye contact, or from contaminated swimming pool water, causing follicular conjunctivitis, also known as swimming pool conjunctivitis. The lesions are similar to trachoma, but there is no corneal pannus and no conjunctival scarring. They usually heal within weeks or months without sequelae.

Urogenital tract infection: Transmitted through sexual contact, caused by the trachoma organism variant DK serotype. In men, symptoms often present as urethritis, which can be relieved without treatment, but most cases turn into chronic diseases with periodic exacerbations, and may be complicated by epididymitis, proctitis, etc. In women, it can cause urethritis, cervicitis, etc., and salpingitis is a more serious complication. This serotype can sometimes cause Chlamydia trachomatis pneumonia.

Lymphogranuloma venereum: caused by Chlamydia trachomatis LGV biovar. LGV is transmitted through sexual contact and is a sexually transmitted disease. In men, the disease invades the inguinal lymph nodes, causing suppurative lymphadenitis and chronic lymphogranuloma. In women, the perineum, anus, and rectum may be invaded, causing stenosis of the perineum, anus, and rectum.

The above introduces the diseases that are easily caused by Chlamydia trachomatis. I hope it can help you better understand the harm of Chlamydia trachomatis. No matter which disease caused by Chlamydia trachomatis you are infected with, you must receive timely treatment. If you do not treat it in time and allow the disease to worsen, the consequences will be very serious and you must take it seriously. For patients with trachoma, which is the most common disease, they should use towels and other personal toiletries separately and try not to spread it to others.
