Malasseziomycetes
''Malassezia'' (formerly known as ''Pityrosporum'') is a genus of fungi. It is the sole genus in family Malasseziaceae, which is the only family in order Malasseziales, itself the single member of class Malasseziomycetes. ''Malassezia'' species are naturally found on the skin surfaces of many animals, including humans. In occasional opportunistic infections, some species can cause hypopigmentation or hyperpigmentation on the trunk and other locations in humans. Allergy tests for these fungi are available. Systematics Due to progressive changes in their nomenclature, some confusion exists about the naming and classification of ''Malassezia'' yeast species. Work on these yeasts has been complicated because they require specific growth media and grow very slowly in laboratory culture. ''Malassezia'' were originally identified by the French scientist Louis-Charles Malassez in the late nineteenth century. Raymond Sabouraud identified a dandruff-causing organism in 1904 and called i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ustilaginomycotina
The Ustilaginomycotina is a subdivision within the division Basidiomycota of the kingdom Fungi. It consists of the classes Ustilaginomycetes and Exobasidiomycetes, and in 2014 the subdivision was reclassified and the two additional classes Malasseziomycetes and Moniliellomycetes added. The name was first published by Doweld in 2001; Bauer and colleagues later published it in 2006 as an isonym. Ustilagomycotina and Agaricomycotina are considered to be sister groups, and they are in turn sister groups to the subdivision Pucciniomycotina. Ustilaginomycotina comprises 115 genera with more than 1700 species. The subdivision is mostly plant parasites on vascular plants, and the distribution of the subdivision is therefore restricted to the distribution of the host. The group is also called the true smut fungi because of the production of teliospores. The name smut is still used as a term since it circumscribes the organization and life cycle of Ustilaginomycotina, but it is not a tax ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipid
Lipids are a broad group of naturally-occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries, and in nanotechnology. Lipids may be broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, multilamellar/unilamellar liposomes, or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks": ketoacyl and isoprene groups. Using this approach, lipids may be divided into eight categories: fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides (derived from condensati ...

Malassezia Caprae
''Malassezia caprae'' is a fungus first isolated in goats, which can cause opportunistic infections in animals. Its type strain is MA383=CBS 10434. This species will not grow without any lipid supplementation. It grows slowly and forms small colonies (average diameter ). In the lab, colonies will not grow at temperatures of 40 °C, differing from '' M. sympodialis''-related species, such '' M. dermatis'' and '' M. nana'', which can grow at this temperature. ''Malassezia caprae'' cells are ellipsoid An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the ...al to more or less spherical.

Turquoise-fronted Amazon
The turquoise-fronted amazon (''Amazona aestiva''), also called the turquoise-fronted parrot, the blue-fronted amazon and the blue-fronted parrot, is a South American species of amazon parrot and one of the most common amazon parrots kept in captivity as a pet or companion parrot. Its common name is derived from the distinctive turquoise marking on its head just above its beak. Taxonomy The turquoise-fronted amazon was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae''. Its specific epithet is the feminine form of the Latin adjective ''aestivus'', "of the summer". Two subspecies are recognized: *''A. a. aestiva'' (nominate) is found in eastern Brazil.Forshaw, p. 558 The leading edge of the wing ("shoulder") is red. *''A. a. xanthopteryx'' occurs from northern and eastern Bolivia through adjacent parts of Brazil, to Paraguay and northern Argentina. The "shoulder" is partly or wholly yellow. Generally with more ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malassezia Arunalokei
''Malassezia arunalokei'' is a species of yeast-like fungus that was identified as a new to science in 2016. It has been isolated from the skin of both seborrheic dermatitis patients and healthy individuals from India. A combination of several phenotypic characteristics distinguish this species from others in genus ''Malassezia''. These include: colony morphology (when grown on nutrient agar); the absence of activity from the enzyme catalase; growth at ; and the precipitation that results when grown with the chemicals Tween 20 or Cremophor EL. The type strain is NCCPF 127130 (housed at the National Culture Collection of Pathogenic Fungi in New Delhi), which was isolated from the scalp of an individual with seborrheic dermatitis in Chandigarh, India. The most closely related fungus is '' M. restricta'', but the two internal transcribed spacer DNA sequences of these species differ by 6.4%, which meets the generally accepted criteria for genetic distinctiveness.

Author Citation (botany)
In botanical nomenclature, author citation is the way of citing the person or group of people who validly published a botanical name, i.e. who first published the name while fulfilling the formal requirements as specified by the '' International Code of Nomenclature for algae, fungi, and plants'' (''ICN''). In cases where a species is no longer in its original generic placement (i.e. a new combination of genus and specific epithet), both the authority for the original genus placement and that for the new combination are given (the former in parentheses). In botany, it is customary (though not obligatory) to abbreviate author names according to a recognised list of standard abbreviations. There are differences between the botanical code and the normal practice in zoology. In zoology, the publication year is given following the author names and the authorship of a new combination is normally omitted. A small number of more specialized practices also vary between the recommendation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''.
