''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 it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Principle Of Priority
270px, '' valid name. Priority is a fundamental principle of modern botanical nomenclature and zoological nomenclature. Essentially, it is the principle of recognising the first valid application of a name to a plant or animal. There are two aspects to this: # The first formal scientific name given to a plant or animal taxon shall be the name that is to be used, called the valid name in zoology and correct name in botany (principle of synonymy). # Once a name has been used, no subsequent publication of that name for another taxon shall be valid (zoology) or validly published (botany) (principle of homonymy). Note that nomenclature for botany and zoology is independent, and the rules of priority regarding homonyms operate within each discipline but not between them. There are formal provisions for making exceptions to the principle of priority under each of the Codes. If an archaic or obscure prior name is discovered for an established taxon, the current name can be declared ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
