Ctenomyces Serratus
''Ctenomyces serratus'' is a keratinophilic fungal soil saprotroph classified by the German mycologist, Michael Emil Eduard Eidam in 1880, who found it growing on an old decayed feather. Many accounts have shown that it has a global distribution, having been isolated in select soils as well as on feathers and other substrates with high keratin content. It has also been found in indoor dust of hospitals and houses in Kanpur, Northern India and as a common keratinophilic soil fungus in urban Berlin. This species has been associated with nail infections in humans as well as skin lesions and slower hair growth in guinea pigs. History and taxonomy ''Ctenomyces serratus'' was first discovered on a rotten, old feather by Eidam in 1880. When discovering it, Eidam observed different structures and assumed he was looking at different stages of growth of the fungus. However, in 1956 Benjamin revealed that Eidam's observations unintentionally included a species of ''Arthroderma''. The fung ...

Nannizzia
''Nannizzia'' is a genus of fungus in the family Arthrodermataceae. The genus name of ''Nannizzia'' is in honour of Arturo Nannizzi (1877-1961), who was an Italian botanist, docent in Mycology and in 1935 was Director of the Botanical Garden in Siena. The genus was circumscribed In geometry, a circumscribed circle for a set of points is a circle passing through each of them. Such a circle is said to ''circumscribe'' the points or a polygon formed from them; such a polygon is said to be ''inscribed'' in the circle. * Circum ... by Phyllis Margaret Stockdale in Sabouraudia vol.1 on page 45 in 1961.

In bino ... of fungus, which includes the parasitic varieties that cause tinea, including athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp. Trichophyton fungi are molds characterized by the development of both smooth-walled macro- and microconidia. Macroconidia are mostly borne laterally directly on the hyphae or on short pedicels, and are thin- or thick-walled, clavate to fusiform, and range from 4 to 8 by 8 to 50 μm in size. Macroconidia are few or absent in many species. Microconidia are spherical, pyriform to clavate or of irregular shape, and range from 2 to 3 by 2 to 4 μm in size.

Epidermophyton Floccosum
''Epidermophyton floccosum'' is a filamentous fungus that causes skin and nail infections in humans. This anthropophilic dermatophyte can lead to diseases such as tinea pedis (athlete's foot), tinea cruris, tinea corporis and onychomycosis. Diagnostic approaches of the fungal infection include physical examination, culture testing, and molecular detection. Topical antifungal treatment, such as the use of terbinafine, itraconazole, voriconazole, and ketoconazole, is often effective. ''E. floccosum'' is one of the 2 species in the genus '' Epidermophyton''. During the 20th century, this species was the fourth most common cause of dermatophytosis in North America. This ascomycete has a worldwide distribution but is more commonly isolated from patients in tropical and subtropical areas. The non-soil associated fungus has no specific growth conditions and shows characteristic smooth club-shaped macroconidia under the microscope. History and taxonomy The fungus was first isolated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epidermophyton
''Epidermophyton'' is a genus of fungus causing superficial and cutaneous mycoses, including ''E. floccosum'', and causes tinea corporis (ringworm), tinea cruris (jock itch), tinea pedis (athlete's foot), and tinea unguium Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin (a dermatomycosis), that may affect skin, hair, and nails. Typically it results in a red, itchy, scaly, circular rash. Hair loss may occur in the area aff ... (fungal infection of the nail bed).

Microsporum
''Microsporum'' is a genus of fungi that causes tinea capitis, tinea corporis, ringworm, and other dermatophytoses (fungal infections of the skin). ''Microsporum'' forms both macroconidia (large asexual reproductive structures) and microconidia (smaller asexual reproductive structures) on short conidiophores. Macroconidia are hyaline, multiseptate, variable in form, fusiform, spindle-shaped to obovate, 7–20 by 30–160 um in size, with thin or thick echinulate to verrucose cell walls. Their shape, size and cell wall features are important characteristics for species identification. Microconidia are hyaline, single-celled, pyriform to clavate, smooth-walled, 2.5–3.5 by 4–7 um in size and are not diagnostic for any one species. The separation of this genus from ''Trichophyton'' is essentially based on the roughness of the macroconidial cell wall, although in practice this may sometimes be difficult to observe. Seventeen species of ''Microsporum'' have been de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dermatophytes
Dermatophyte (from Greek '' derma'' "skin" ( GEN ''dermatos'') and ''phyton'' "plant") is a common label for a group of fungus of '' Arthrodermataceae'' that commonly causes skin disease in animals and humans. Traditionally, these anamorphic (asexual or imperfect fungi) mold genera are: '' Microsporum'', '' Epidermophyton'' and ''Trichophyton''. There are about 40 species in these three genera. Species capable of reproducing sexually belong in the teleomorphic genus Arthroderma, of the Ascomycota (see Teleomorph, anamorph and holomorph for more information on this type of fungal life cycle). As of 2019 a total of nine genera are identified and new phylogenetic taxonomy has been proposed. Dermatophytes cause infections of the skin, hair, and nails, obtaining nutrients from keratinized material. The organisms colonize the keratin tissues causing inflammation as the host responds to metabolic byproducts. Colonies of dermatophytes are usually restricted to the nonliving cornifie ...

Onygenales
The Onygenales are an order of fungi in the class Eurotiomycetes and division Ascomycota. The order's last common ancestor is estimated to have lived 150 million years ago. Onygenales can consume and break down keratin, the main component of the outer layer of skin. They are primarily found on animals, droppings, and areas frequented by animals. Many are dimorphic, and can change from mold to yeast form depending on their environment. Many onygenalean fungi are pathogen In biology, a pathogen (, "suffering", "passion" and , "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a Germ theory of d ...s. One species, '' Trichophyton rubrum'', is the primary cause of athlete's foot. This order also includes the '' Coccidioides'' implicated in Valley fever. The Onygenales are important as emerging human pathogens because of the rising rates of immunosuppress ...

Frederick Currey (mycologist)
Frederick Currey (August 1819 – 8 September 1881) was an English mycologist and botanist. Biography Frederick Currey was one of the brothers of the architect Henry Currey (1820–1900). Their father was Benjamin Currey (1786–1848), Clerk of the Parliaments. After education at Eton College, Frederick Currey matriculated in 1837 at Trinity College, Cambridge. There he graduated in 1841 with a B.A. and in 1844 with an M.A. He was admitted at Lincoln's Inn in June 1839 and called to the bar in 1844. He practised as conveyancer and equity draughtsman. Currey's scientific publications were primarily in the ''Transactions of the Linnean Society'', the ''Quarterly Journal of Microscopical Science'', and other learned journals. He translated several German textbooks, including Hermann Schacht's 1851 book ''Das Mikroscop und seine Anwendung insbesondere für Pflanzen-Anatomie und Physiologie'' (''The microscope, and its application to vegetable anatomy and physiology'', 1853;Geoffrey C ...
