A sexually transmitted infection (STI), also referred to as a sexually transmitted disease (STD) and the older term venereal disease (VD), is an infection that is spread by sexual activity, especially vaginal intercourse, anal sex, oral sex, or sometimes manual sex.
Humans are the only known natural reservoir for subspecies pallidum. [34] It is unable to survive more than a few days without a host. [22] This is due to its small genome (1.14Mbp) failing to encode the metabolic pathways necessary to make most of its macronutrients. [22] It has a slow doubling time of greater than 30 hours. [22]
Trichomonas vaginalis from a vaginal swab. This is a heavy infection; there were probably thousands of trichomonads in the vagina. Alfred Francois Donné (1801–1878) was the first to describe a procedure to diagnose trichomoniasis through "the microscopic observation of motile protozoa in vaginal or cervical secretions" in 1836.
The human genital tract is the only reservoir for this species. Trichomonas is transmitted through sexual or genital contact. [14] The single-celled protozoan produces mechanical stress on host cells and then ingests cell fragments after cell death. [15]
The rates of three STDs — gonorrhea, chlamydia and syphilis — have reached an all-time high in the U.S., according to a new report from the Centers for Disease Control and Prevention.
Vaginal hypoplasia is the underdevelopment or incomplete development of the vagina. Vaginal hypoplasia can vary in severity from being smaller than normal to being completely absent. The absence of a vagina is a result of vaginal agenesis. Diagnostically, it may look similar to a vaginal obstruction.
If left untreated, gonorrhea can spread from the original site of infection and infect and damage the joints, skin, and other organs. Indications of this can include fever, skin rashes, sores, and joint pain and swelling. [21] In advanced cases, gonorrhea may cause a general feeling of tiredness similar to other infections.
