A mouse biovar of chlamydia trachoma is considered a more virulent form of trachoma, and can invade both the reproductive tract and urinary tract. In mice, after inoculation vaginally with chlamydia suis in group one, and chlamydia trachoma in group two, chlamydia suis and chlamydia trachoma were isolated from both the uterus and fallopian tubes, weeks after inoculation. Long term, sexually transmitted chlamydia trachoma has the potential to cause many chronic diseases, including urinary disease, interstitial cystitis, kidney disease, autoimmune disease, multiple sclerosis, fibromyalgia, chronic fatigue, arthritis, eye diseases, and cancer.
