When a chlamydia infection is present, the bacteria that causes chlamydia, chlamydia trachomatis, can be found in the mouth and spread through oral contact, according to the U.S. Centers for Disease Control and Prevention. In most cases, the bacteria is asymptomatic in the mouth, causing no noticeable sign of infection or link to pharyngitis.
Because chlamydia is often asymptomatic and causes damage to the female reproductive system if left untreated, routine chlamydia screening is recommended for women, according to the CDC website. Transmitted through oral, anal and vaginal sex, chlamydia symptoms, when present, include burning during urination, discharge and abdominal pain. Chlamydia is diagnosed through laboratory testing using vaginal fluid or urine. Chlamydia is treated using a course of antibiotics that typically lasts for one week. While taking antibiotics, it is important to avoid sexual intercourse to ensure that the infection clears completely. All sexual partners must be treated after a diagnosis of chlamydia to prevent re-infection. Medication stops the current infection, but it does not prevent a future infection or repair any damage that the infection has done to the body. Using condoms regularly and correctly minimizes the risk of contracting chlamydia, but the only way to prevent it is to abstain from sex or remain in a mutually monogamous relationship.
