Bacterial vaginosis (BV) is a disease of the vagina caused by excessive growth of bacteria. Common symptoms include increased vaginal discharge that often smells like fish. The discharge is usually white or gray in color. Burning with urination may occur. Itching is uncommon. Occasionally, there may be no symptoms. Having BV approximately doubles the risk of infection by a number of sexually transmitted infections, including HIV/AIDS. It also increases the risk of early delivery among pregnant women.

<span class="mw-page-title-main">Vagina</span> Part of the female genital tract

In mammals, the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vestibule to the cervix. The outer vaginal opening is normally partly covered by a thin layer of mucosal tissue called the hymen. At the deep end, the cervix bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle.

Vaginitis, also known as vulvovaginitis, is inflammation of the vagina and vulva. Symptoms may include itching, burning, pain, discharge, and a bad smell. Certain types of vaginitis may result in complications during pregnancy.

<span class="mw-page-title-main">Female reproductive system</span> Reproductive system of human females

The female reproductive system is made up of the internal and external sex organs that function in the reproduction of new offspring. In humans, the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes, and to carry a fetus to full term. The internal sex organs are the vagina, uterus, fallopian tubes, and ovaries. The female reproductive tract includes the vagina, uterus, and fallopian tubes and is prone to infections. The vagina allows for sexual intercourse and childbirth, and is connected to the uterus at the cervix. The uterus or womb accommodates the embryo which develops into the fetus. The uterus also produces secretions which help the transit of sperm to the fallopian tubes, where sperm fertilize ova produced by the ovaries. The external sex organs are also known as the genitals and these are the organs of the vulva including the labia, clitoris, and vaginal opening.

Salpingitis is an infection causing inflammation in the Fallopian tubes. It is often included in the umbrella term of pelvic inflammatory disease (PID), along with endometritis, oophoritis, myometritis, parametritis, and peritonitis.

<span class="mw-page-title-main">Vaginal discharge</span> Medical condition

Vaginal discharge is a mixture of liquid, cells, and bacteria that lubricate and protect the vagina. This mixture is constantly produced by the cells of the vagina and cervix, and it exits the body through the vaginal opening. The composition, amount, and quality of discharge varies between individuals and can vary throughout the menstrual cycle and throughout the stages of sexual and reproductive development. Normal vaginal discharge may have a thin, watery consistency or a thick, sticky consistency, and it may be clear or white in color. Normal vaginal discharge may be large in volume but typically does not have a strong odor, nor is it typically associated with itching or pain. While most discharge is considered physiologic or represents normal functioning of the body, some changes in discharge can reflect infection or other pathological processes. Infections that may cause changes in vaginal discharge include vaginal yeast infections, bacterial vaginosis, and sexually transmitted infections. The characteristics of abnormal vaginal discharge vary depending on the cause, but common features include a change in color, a foul odor, and associated symptoms such as itching, burning, pelvic pain, or pain during sexual intercourse.

A vaginal disease is a pathological condition that affects part or all of the vagina.

<span class="mw-page-title-main">Vaginal yeast infection</span> Medical condition

Vaginal yeast infection, also known as candidal vulvovaginitis and vaginal thrush, is excessive growth of yeast in the vagina that results in irritation. The most common symptom is vaginal itching, which may be severe. Other symptoms include burning with urination, a thick, white vaginal discharge that typically does not smell bad, pain during sex, and redness around the vagina. Symptoms often worsen just before a woman's period.

Atrophic vaginitis is inflammation of the vagina as a result of tissue thinning due to not enough estrogen. Symptoms may include pain with sex, vaginal itchiness or dryness, and an urge to urinate or burning with urination. It generally does not resolve without ongoing treatment. Complications may include urinary tract infections.

<span class="mw-page-title-main">Aerobic vaginitis</span> Medical condition

Aerobic vaginitis (AV) is a form of vaginitis first described by Donders et al. in 2002. It is characterized by a more or less severe disruption of the lactobacillary flora, along with inflammation, atrophy, and the presence of a predominantly aerobic microflora, composed of enteric commensals or pathogens.

Anaerococcus is a genus of bacteria. Its type species is Anaerococcus prevotii. These bacteria are Gram-positive and strictly anaerobic. The genus Anaerococcus was proposed in 2001. Its genome was sequenced in August 2009. The genus Anaerococcus is one of six genera classified within the group GPAC. These six genera are found in the human body as part of the commensal human microbiota.

<span class="mw-page-title-main">Vaginal epithelium</span>

The vaginal epithelium is the inner lining of the vagina consisting of multiple layers of (squamous) cells. The basal membrane provides the support for the first layer of the epithelium-the basal layer. The intermediate layers lie upon the basal layer, and the superficial layer is the outermost layer of the epithelium. Anatomists have described the epithelium as consisting of as many as 40 distinct layers. The mucus found on the epithelium is secreted by the cervix and uterus. The rugae of the epithelium create an involuted surface and result in a large surface area that covers 360 cm2. This large surface area allows the trans-epithelial absorption of some medications via the vaginal route.

The term Vaginitis emphysematosa is related to Women's Reproductive Health and coined by Zweifel in 1877. The cases of Vaginitis emphysematosa are rare. The most important thing is that women never consult with the doctors for particularly Vaginitis emphysematosa but when they visit a doctor for some other reproductive health issue, they diagnose with the Vaginitis emphysematosa fortunately. Vaginitis emphysematosa is not common and Gynaecologists rarely know about it. Basically, this is characterised by gas-filled cysts in the mucosa of the vagina. Vaginitis emphysematosa is usually a self limited cystic disorder of the vagina. It is a very rare condition and has not much specific features to arouse clinical suspicion.

<span class="mw-page-title-main">Lactobacillus vaccine</span> Vaccine using an inactivated strain of Lactobacillus

Lactobacillus vaccines are used in the therapy and prophylaxis of non-specific bacterial vaginitis and trichomoniasis. The vaccines consist of specific inactivated strains of Lactobacilli, called "aberrant" strains in the relevant literature dating from the 1980s. These strains were isolated from the vaginal secretions of patients with acute colpitis. The lactobacilli in question are polymorphic, often shortened or coccoid in shape and do not produce an acidic, anti-pathogenic vaginal environment. A colonization with aberrant lactobacilli has been associated with an increased susceptibility to vaginal infections and a high rate of relapse following antimicrobial treatment. Intramuscular administration of inactivated aberrant lactobacilli provokes a humoral immune response. The production of specific antibodies both in serum and in the vaginal secretion has been demonstrated. As a result of the immune stimulation, the abnormal lactobacilli are inhibited, the population of normal, rod-shaped lactobacilli can grow and exert its defense functions against pathogenic microorganisms.

Limosilactobacillus vaginalis is a lactic acid bacterium that is a normal, but infrequent part of the vaginal microbiome.

Anaerococcus hydrogenalis is a bacterium from the family Peptoniphilaceae. It is present in vaginal discharges and ovarian abscesses. Presence of Anaerococcus hydrogenalis in the gut metabolism and their coline consumption has been associated to cardiovascular diseases. Contrary to most of the species in this genus, Anaerococcus hydrogenalis is indole-positive. Also, some strains in this specie can produce urease.
