Sneathi sanguinegens contributes to bacterial vaginosis and preterm birth, and may contribute to urethritis in men who do not have any other diagnosis.
Sneathia amnii is cytotoxic to vaginal cells and kills eukaryotic cells (like mitochondria) in culture, while also contributing to preterm birth.
Saccharomyces cerevisiae is a yeast that can inhabit the vagina, but is most famous for fermentation in wine, baking bread and brewing beer, with vulvovaginitis uncommon, but more likely to occur more in women who work in or near someone who works in a bakery or brewery.
Pseudomonas aeruginosa can cause vulvovaginal and urinary tract infections, but tends to prefer other locations on the human body to infect.
Proteus vulgaris typically lives in the digestive tract of humans, causing infections in wounds and as opportunity arises, infections in the urinary tract.
Proteus mirabilis is a bacteria that commonly causes urinary tract infections and can contribute to bacterial vaginosis.
Prevotella timonensis commonly lives in healthy mouths and vaginal tracts, but is an opportunistic pathogen, sometimes leading to unpleasant symptoms, like bacterial vaginosis or abscesses in the mouth.
P. intermedia is involved in mouth infections, is found more in pregnant women, and may be involved with bacterial vaginosis.
Prevotella disiens was formerly known as part of Bacteroides disiens. P. disiens is most commonly found in the mouth, and has been related to bacterial vaginosis.
A member of the Prevotella species that can contribute to infections in the vagina and reproductive tract of women, such as bacterial vaginosis, and in the mouth.
Prevotella buccalis naturally lives in the mouth and vagina, but is considered an opportunistic pathogen, and is associated with bacterial vaginosis.
Prevotella bivia is found in many human infections, including the vagina, contributing to bacterial vaginosis and pelvic inflammatory disease.
Prevotella amnii has been isolated from the endometrial lining of the uterus, and in women with pelvic inflammatory disease (PID), and bacterial vaginosis.
P. gingivalis is a pathogenic bacteria frequently involved in gum disease, however it has been found in women with BV and women who are having trouble conceiving.
Highly associated with periodontal disease, causing infections in the gums and tooth roots. Relatives of this species cause or contribute to vaginal infections, and so B. endodontalis is flagged as a possible cause or contributor of vulvovaginal infections or dysbiosis. Bacteria that cause gum disease may survive in the vaginal mucosal environment given the right
Porphyromonas asaccharolytica is a bacteria that can inhabit the vagina and contribute to or cause vulvovaginal infections or dysbiosis, such as bacterial vaginosis.
Peptostreptococcus tetradius is microbe found in vaginal and urinary tract infections in women, linked with bacterial vaginosis.
Lactobacillus iners in sufficient colonies may predispose someone to bacterial vaginosis. L. iners and sulfur (and cysteine) L. iners growth is dependent on L-cysteine in vitro. Researchers traced this phenotype to the absence of canonical cysteine biosynthesis pathways and a restricted repertoire of cysteine-related transport mechanisms1. Cysteine concentrations in cervicovaginal lavage samples correlate with Lactobacillus abundance in
Peptostreptococcus species harmlessly inhabit our mouths, skin, intestines, vagina, and urinary tract, but under stress or a compromised immune system, can become pathogenic.
