List Of Bacterial Vaginosis Microbiota
Bacterial vaginosis is caused by an imbalance of the naturally occurring bacteria in the vagina. The normally predominant species of ''Lactobacilli'' are markedly reduced. This is the list of organisms that are found in the vagina that are associated with bacterial vaginosis, an infectious disease of the vagina caused by excessive growth of specific bacteria. The census and relationships among the microbiota are altered in BV resulting in a complex bacterial milieu. Some species have been identified relatively recently. Having infections with the listed pathogens increases the risk of acquiring other sexually transmitted infections including HIV/AIDS.

Vaginal Flora
Vaginal flora, vaginal microbiota or vaginal microbiome are the microorganisms that colonize the vagina. They were discovered by the German gynecologist Albert Döderlein in 1892 and are part of the overall human flora. The amount and type of bacteria present have significant implications for an individual's overall health. The primary colonizing bacteria of a healthy individual are of the genus '' Lactobacillus'', such as '' L. crispatus'', and the lactic acid they produce is thought to protect against infection by pathogenic species. Lactobacilli The primary colonizing bacteria of a healthy individual are of the genus '' Lactobacillus'' (90–95%), the most common being '' L. crispatus'', '' L. iners'', '' L. jensenii'', and '' L. gasseri''. Since the first description of lactobacilli by Döderlein, lactobacilli have been generally considered the gatekeepers of the vaginal ecosystem. Lactobacilli have been shown to inhibit in vitro growth of pathogenic microorganisms, e.g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eggerthella Lenta
''Eggarthella lenta'' is a Gram-positive, anaerobic species of bacteria which comprises part of the human microbiome. It has been found in the human gastrointestinal tract, female reproductive system and male prostate. Occasionally it can cause disease by spreading to other areas, including bloodstream infections, liver abscesses, bacterial vaginosis and meningitis. ''E. lenta'' levels are enriched in inflammatory bowel disease, and the bacterium has been shown to activate T helper 17 cells. It has been shown to worsen colitis in mice models. ''E. lenta'' has been found to be present in higher levels in the gut of people with Graves' disease . ''E. lenta'' has been shown to inactivate the cardiac drug digoxin Digoxin (better known as Digitalis), sold under the brand name Lanoxin among others, is a medication used to treat various heart conditions. Most frequently it is used for atrial fibrillation, atrial flutter, and heart failure. Digoxin is on .... The species was k ...

Peptostreptococcus Anaerobius
''Peptostreptococcus anaerobius'' is a species of bacteria belonging to the ''Peptostreptococcus'' genus of anaerobic, Gram-positive, non-spore forming bacteria. The cells are small, spherical, and can occur in short chains, in pairs or individually. ''Peptostreptococcus'' are slow-growing bacteria sometimes resistance to antimicrobial drugs. ''Peptostreptococcus anaerobius'' is present as part of the microbiota of the lower reproductive tract of women and has been recovered from women with pelvic inflammatory disease and bacterial vaginosis.

Peptoniphilus
''Peptoniphilus'' is a genus of bacteria in the phylum Bacillota ( Bacteria). Etymology The name ''Peptoniphilus'' derives from:New Latin noun ''peptonum'', peptone; New Latin adjective ''philus'' from Greek adjective ''philos (φίλος)'' meaning friend, loving; New Latin masculine gender noun ''Peptoniphilus'', friend of peptone, referring to the use of peptone as a major energy source. Classification Peptoniphilus are gram positive anaerobic cocci that were formerly classified in the genus Peptostreptococcus. They are non-saccharolytic, use peptone as a major energy source and produce butyrate. Clinical relevance This genus is part of the vaginal and gut microbiota. They have been reported to as present in diabetic skin and soft tissue infections, bone and joint infections, surgical site infections, chorioamnionitis and bloodstream infections. They are typically found as part of polymicrobial infections but are difficult to recover with usual clinical cultures. They ha ...

Peptococcus
''Peptococcus'' is a Gram-positive bacterium genus in the family Peptococcaceae. Species in the genus are part of the human microbiome, especially in the bacteria that form the gut flora. They are part of the flora of the mouth, upper respiratory tract and large intestine. Mezlocillin is an antibiotic that is effective against ''Peptococcus'' species. '' Peptococcus niger'' is the only species left in the genus. All others have been moved to ''Peptostreptococcus''.

Mycoplasma Parvum
''Mycoplasma'' is a genus of bacteria that, like the other members of the class ''Mollicutes'', lack a cell wall around their cell membranes. Peptidoglycan (murein) is absent. This characteristic makes them naturally resistant to antibiotics that target cell wall synthesis (like the beta-lactam antibiotics). They can be parasitic or saprotrophic. Several species are pathogenic in humans, including '' M. pneumoniae'', which is an important cause of "walking" pneumonia and other respiratory disorders, and '' M. genitalium'', which is believed to be involved in pelvic inflammatory diseases. ''Mycoplasma'' species (like the other species of the class ''Mollicutes'') are among the smallest organisms yet discovered, can survive without oxygen, and come in various shapes. For example, ''M. genitalium'' is flask-shaped (about 300 x 600 nm), while ''M. pneumoniae'' is more elongated (about 100 x 1000 nm), many ''Mycoplasma'' species are coccoid.

Mycoplasma Hominis
''Mycoplasma hominis'' is a species of bacteria in the genus ''Mycoplasma''. ''M.hominis'' has the ability to penetrate the interior of human cells. Along with ureaplasmas, mycoplasmas are the smallest free-living organisms known. They have no cell wall and therefore do not Gram stain. ''Mycoplasma hominis'' is associated with pelvic inflammatory disease and bacterial vaginosis. It is also associated with male infertility. This species causes a sexually transmitted disease. It is susceptible to the antibiotic clindamycin. Growth of "fried egg" colonies on glucose agar medium within 24–48 hours is a characteristic of ''Mycoplasma hominis''. This pathogen may latently infect the chorionic villi tissues of pregnant women, thereby impacting pregnancy outcome. Biology and biochemistry Type and morphology ''Mycoplasma hominis'' is an opportunistic human mycoplasma species residing in the lower urogenital tract. It is a common human urogenital Mycoplasma species that lacks a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobiluncus
''Mobiluncus'' is a genus of Gram-positive, anaerobic, rod-shaped bacteria. These bacteria may be stained either Gram-negative or Gram-variable. However, they are classified as Gram-positive rods due to the fact that they possess a Gram-positive cell wall, lack endotoxin and are sensitive to vancomycin, erythromycin and ampicillin, but resistant to colistin.Medical Microbiology 7th Edition, Patrick R. Murrau, PhD These organisms are found in the human vagina, particularly in association with ''Gardnerella vaginalis ''Gardnerella vaginalis'' is a species of Gram-variable-staining facultative anaerobic bacteria.

Gardnerella Vaginalis
''Gardnerella vaginalis'' is a species of Gram-variable-staining facultative anaerobic bacteria. The organisms are small (1.0–1.5 μm in diameter) non-spore-forming, nonmotile coccobacilli. Once classified as ''Haemophilus vaginalis'' and afterwards as ''Corynebacterium vaginalis'', ''G. vaginalis'' grows as small, circular, convex, gray colonies on chocolate agar; it also grows on agar. A selective medium for ''G. vaginalis'' is colistin- oxolinic acid blood agar. Clinical significance ''G. vaginalis'' is a facultatively anaerobic Gram-variable rod that is involved, together with many other bacteria, mostly anaerobic, in bacterial vaginosis in some women as a result of a disruption in the normal vaginal microflora. The resident facultative anaerobic ''Lactobacillus'' population in the vagina is responsible for the acidic environment. Once the anaerobes have supplanted the normal vaginal bacteria, prescription antibiotics with anaerobic coverage may have to be given ...
