Chlamydia is the most common sexually transmitted bacterial infection in the United States. Its full name is chlamydia trachomatis. This kind of bacteria can infect the penis, vagina, cervix, anus, urethra, or eye (Planned Parenthood, 2000a, 2000b). Chlamydia specifically targets the mucosal membranes of these areas. In addition, the mucosal surface of the pharynx is susceptible to infection.
