Ureaplasma Parvum
''Ureaplasma parvum'' is a species of ''Ureaplasma'', a genus of bacteria belonging to the family Mycoplasmataceae. In Indonesia, ureaplasma parvum is most commonly contracted through contact with public toilets. ''Ureaplasma parvum'' was formerly known as ''Ureaplasma urealyticum biovar'' 1. ''Ureaplasma parvum'' has been identified as being a commensal in the uterus as part of the microbiome in healthy women of reproductive age. In addition, this pathogen may latently infect the chorionic villi tissues of pregnant women, thereby impacting pregnancy outcome. Classification ''Ureaplasma spp''. are one of the smallest known clonal bacteria. They are closely related to mycoplasmas as they lack a peptidoglycan cell wall, metabolize cholesterol, and require urea for ATP synthesis. The Ureaplasma genus has 14 serotypes A serotype or serovar is a distinct variation within a species of bacteria or virus or among immune cells of different individuals. These microorganisms, viruses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycoplasmataceae
Mycoplasmataceae is a family of bacteria in the order Mycoplasmatales. This family consists of the genera ''Mycoplasma'' and ''Ureaplasma''. In 1967, the order Mycoplasmatales was incorporated into the class Mollicutes. Many species are sexually transmitted and cause pelvic inflammatory disease. Taxonomy ''Mycoplasma'' ''Mycoplasma ''refers to a genus of bacteria that lack a cell wall and possess a three-layered cellular membrane. They can be parasitic or saprotrophic. Several species are sexually transmitted and pathogenic in humans. Others are found on cats, dogs, and barnyard fowl. ''Ureaplasma'' ''Ureaplasma'' is the second of two genera of bacteria belonging to the family Mycoplasmataceae. As the name implies, ureaplasma is urease positive. This genera is distinct from other genera in Mollicutes in that it hydrolyses urea for generation of ATP. ''Ureaplasma'' ''spp.'' as human pathogens Both ''Ureaplasma urealyticum'' and '' Ureaplasma parvum'' have been identified as ...

Uterine Microbiome
The uterine microbiome is the commensal, nonpathogenic, bacteria, viruses, yeasts/fungi present in a healthy uterus, amniotic fluid and endometrium and the specific environment which they inhabit. It has been only recently confirmed that the uterus and its tissues are not sterile. Due to improved 16S rRNA gene sequencing techniques, detection of bacteria that are present in low numbers is possible. Using this procedure that allows the detection of bacteria that cannot be cultured outside the body, studies of microbiota present in the uterus are expected to increase. Uterine microbiome and fertility Evidence shows that the presence of uterine bacterial 16S rRNA gene amplification is not the result of sampling or analysis error and deserves to be acknowledged. Concept of the sterile endometrium, and the uterine compartment in general, is outdated; although the true core uterine microbiome still needs to be assessed, and may vary across cultural and regional divides.

Chorionic Villi
Chorionic villi are villi that sprout from the chorion to provide maximal contact area with maternal blood. They are an essential element in pregnancy from a histomorphologic perspective, and are, by definition, a product of conception. Branches of the umbilical arteries carry embryonic blood to the villi. After circulating through the capillaries of the villi, blood returns to the embryo through the umbilical vein. Thus, villi are part of the border between maternal and fetal blood during pregnancy. Structure Villi can also be classified by their relations: * Floating villi float freely in the intervillous space. They exhibit a bi-layered epithelium consisting of cytotrophoblasts with overlaying syncytium ( syncytiotrophoblast). * Anchoring (stem) villi stabilize mechanical integrity of the placental-maternal interface. Development The chorion undergoes rapid proliferation and forms numerous processes, the chorionic villi, which invade and destroy the uterine decidua and a ...

Serotypes
A serotype or serovar is a distinct variation within a species of bacteria or virus or among immune cells of different individuals. These microorganisms, viruses, or cells are classified together based on their surface antigens, allowing the epidemiologic classification of organisms to the subspecies level. A group of serovars with common antigens is called a serogroup or sometimes ''serocomplex''. Serotyping often plays an essential role in determining species and subspecies. The ''Salmonella'' genus of bacteria, for example, has been determined to have over 2600 serotypes. ''Vibrio cholerae'', the species of bacteria that causes cholera Cholera is an infection of the small intestine by some strains of the bacterium ''Vibrio cholerae''. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and ..., has over 200 serotypes, based on cell antigens. Only two of them have been observed to produ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
