Trichophyton Glabrum
''Trichophyton'' is a genus of fungi, 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. Species and their habitat preference According to current classification, the genus includes anthropophilic and zoophilic species. Anthropophilic fungi prefer to infect humans. Zoophilic fungi prefer to infect animals other than humans. Humans and animals are natural reservoirs for parasitic or dermatophytic fungi. Oth ...

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] |
Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trichophyton Mentagrophytes
''Trichophyton mentagrophytes'' is a species in the fungal genus ''Trichophyton''. It is one of three common fungi which cause ringworm in companion animals. It is also the second-most commonly isolated fungus causing tinea infections in humans, and the most common or one of the most common fungi that cause zoonotic skin disease (i.e., transmission of mycotic skin disease from species to species). ''Trichophyton mentagrophytes'' is being frequently isolated from dogs, cats, rabbits, guinea pigs and other rodents, though at least some genetic variants possess the potential of human-to-human transmission, e.g. Type VII and Type VIII. Particular genetic variants of the fungus have distinct geographic ranges. Drug resistance In ''T. mentagrophytes'', antifungal drug resistance is mainly associated with Type VIII isolates. Drug-resistant ''T. mentagrophytes'' strains have been found in many places across Asia and Europe. India is the most affected country, with the rate of microbiolog ...

Anthropophilic
In parasitology, anthropophilia, from the Greek ἅνθρωπος (anthrōpos, "human being") and φιλία (philia, "friendship" or "love"), is a preference of a parasite or dermatophyte for humans over other animals.Braun-Falco, Otto (2000). ''Dermatology'' Springer, Mouchet, Jean; Carnevale, Pierre; Manguin, Sylvie (2008). ''Biodiversity of Malaria in the World.'' John Libbey Eurotext, The related term ''endophilia'' refers specifically to a preference for being in human habitats, especially inside dwellings.Dronamraju, Krishna R.; Arese, Paolo (2005). ''Malaria: Genetic and Evolutionary Aspects.'' Birkhäuser, The term ''zoophilia'', in this context, describes animals which prefer non-human animals for nourishment. Most usage of the term ''anthropophilia'' refers to hematophagous insects (see ''Anopheles'') that prefer human bloodMaggenti, A.R. & Gardner, S. 2005.

Trichophyton Concentricum
''Trichophyton concentricum'' is an anthropophilic dermatophyte believed to be an etiological agent of a type of skin mycosis in humans, evidenced by scaly cutaneous patches on the body known as tinea imbricata. This fungus has been found mainly in the Pacific Islands and South America. Growth and morphology ''Trichophyton concentricum'' produce dense, slow-growing folded colonies which are mostly white to cream colored on Sabouraud's dextrose agar and their hyphae are normally branched, irregular and septate with antler tips resembling T.schoenleinii. The production of conidia is unusual, however when present, microconidia and macroconidia are smooth walled with a diameter of approximately 4 microns and 50 µm respectively. Due to its resemblance to macroconidia, hyphae are sometimes falsely identified as macroconidia. These fungi are also considered to be osmotolerant because of their ability to grown small colonies on 5% NaCl media and are. Hair perforation assays are ...

Zoophilic
Zoophily, or zoogamy, is a form of pollination whereby pollen is transferred by animals, usually by invertebrates but in some cases vertebrates, particularly birds and bats, but also by other animals. Zoophilous species frequently have evolved mechanisms to make themselves more appealing to the particular type of pollinator, e.g. brightly colored or scented flowers, nectar, and appealing shapes and patterns. These plant-animal relationships are often mutually beneficial because of the food source provided in exchange for pollination. Pollination is defined as the transfer of pollen from the anther to the stigma. There are many vectors for pollination, including abiotic (wind and water) and biotic (animal). There are benefits and costs associated with any vector. For instance, using animal pollination is beneficial because the process is more directed and often results in pollination. At the same time it is costly for the plant to produce rewards, such as nectar, to attract anim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dermatophytic
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 cornified la ...
