Trichosporon Cutaneum
''Trichosporon'' is a genus of anamorphic fungi in the family Trichosporonaceae. All species of ''Trichosporon'' are yeasts with no known teleomorphs (sexual states). Most are typically isolated from soil, but several species occur as a natural part of the skin microbiota of humans and other animals. Proliferation of ''Trichosporon'' yeasts in the hair can lead to an unpleasant but non-serious condition known as white piedra. ''Trichosporon'' species can also cause severe opportunistic infections ( trichosporonosis) in immunocompromised individuals. Taxonomy The genus was first described by the German dermatologist Gustav Behrend in 1890, based on yeasts isolated from the hairs of a moustache where they were causing the condition known as "white piedra". Behrend called his new species '' Trichosporon ovoides''. Friedrich Küchenmeister and Rabenhorst had, however, previously described a species in 1867 from the hairs of a wig. They thought that the organism was an alga and ...

Gustav Behrend
Gustav Behrend (10 January 1847 – 1925) was a German dermatologist who was a native of Neustettin (today- Szczecinek, Poland). In 1870 he received his medical doctorate at the University of Berlin, and during the Franco-Prussian War, he served as an assistant at the Reserve Lazareth in Berlin. In 1882 he became a lecturer at Berlin, and in 1891 was appointed chief physician at the Municipal Dispensary for Sexual Diseases. In 1897 he received the title of professor. Behrend specialized in the fields of dermatology and syphilology, also dealing with the subject of prostitution. He was the author of numerous publications, including a well-regarded textbook on skin diseases, titled ''Lehrbuch der Hautkrankheiten'' (1883). He also contributed a number of articles to Albert Eulenburg's ''Real-Encyclopädie der gesamten Heilkunde''.''Gustav Behre ...

Moustache
A moustache (; mustache, ) is a growth of facial hair grown above the upper lip and under the human nose, nose. Moustaches have been worn in various styles throughout history. Etymology The word "moustache" is French language, French, and is derived from the Italian language, Italian ''mustaccio'' (14th century), dialectal ''mostaccio'' (16th century), from Medieval Latin ''mustacchium'' (eighth century), Medieval Greek μουστάκιον (''moustakion''), attested in the ninth century, which ultimately originates as a diminutive of Hellenistic Greek μύσταξ (''mustax'', ''mustak-''), meaning "upper lip" or "facial hair", probably derived from Hellenistic Greek μύλλον (''mullon''), "lip". An individual wearing a moustache is said to be "moustached" or "moustachioed" (the latter often referring to a particularly large or bushy moustache). History Research done on this subject has noticed that the prevalence of moustaches and facial hair in general rise and fall ...

Cheese
Cheese is a type of dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk (usually the milk of cows, buffalo, goats or sheep). During production, milk is usually acidified and either the enzymes of rennet or bacterial enzymes with similar activity are added to cause the casein to coagulate. The solid curds are then separated from the liquid whey and pressed into finished cheese. Some cheeses have aromatic molds on the rind, the outer layer, or throughout. Over a thousand types of cheese exist, produced in various countries. Their styles, textures and flavors depend on the origin of the milk (including the animal's diet), whether they have been pasteurised, the butterfat content, the bacteria and mold, the processing, and how long they have been aged. Herbs, spices, or wood smoke may be used as flavoring agents. Other added ingredients may include black pepper, ...

Cabbage
Cabbage, comprising several cultivars of '' Brassica oleracea'', is a leafy green, red (purple), or white (pale green) biennial plant grown as an annual vegetable crop for its dense-leaved heads. It is descended from the wild cabbage ( ''B. oleracea'' var. ''oleracea''), and belongs to the " cole crops" or brassicas, meaning it is closely related to broccoli and cauliflower (var. ''botrytis''); Brussels sprouts (var. ''gemmifera''); and Savoy cabbage (var. ''sabauda''). A cabbage generally weighs between . Smooth-leafed, firm-headed green cabbages are the most common, with smooth-leafed purple cabbages and crinkle-leafed savoy cabbages of both colours being rarer. Under conditions of long sunny days, such as those found at high northern latitudes in summer, cabbages can grow quite large. , the heaviest cabbage was . Cabbage heads are generally picked during the first year of the plant's life cycle, but plants intended for seed are allowed to grow a second year and m ...

Arthroconidium
Arthroconidia are a type of fungal spore typically produced by segmentation of pre-existing fungal hyphae. Background These spores are asexual and are generally not as durable and environmentally persistent as, for instance, bacterial endospores or chlamydospores. Some medically significant pathogens, such as ''Coccidioides immitis'', and '' Coccidioides posadasii'', both causative agents of coccidioidomycosis (also known as San Joaquin Valley fever), are transmitted through airborne arthroconidia. Additionally, some pathogenic yeasts, such as '' Geotrichum'' and '' Trichosporon'', also reproduce asexually via arthroconidia. The small size of the arthroconidia, 3 to 5  μm, allow them to lodge themselves into the terminal bronchioles of the lung. There, they develop into a thick-walled spherule filled with endospores that cause a pyogenic (pus-causing) inflammation. See also *Conidium A conidium ( ; : conidia), sometimes termed an asexual chlamydospore or chlamydoconid ...

Septum
In biology, a septum (Latin language, Latin for ''something that encloses''; septa) is a wall, dividing a Body cavity, cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the Pulmonary alveolus, alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Septum of the penis, Penile septum, a fibrous w ...

Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 μm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is ...

Cladistic
Cladistics ( ; from Ancient Greek 'branch') is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies) that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a ' grade', which are fruitless to precisely delineate, especially when ...

DNA Sequencing
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, thymine, cytosine, and guanine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, Genographic Project, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid advancements in DNA seque ...

Pleurococcus
''Pleurococcus'' is a genus of green algae in the family Chaetophoraceae that are spherical in shape with a thick cell wall to protect themselves against excessive water loss. They can be found alone or in bunches together forming a slimy layer and grow on moist, dark patches of trees, rocks and soil. The name is derived from the Greek terms πλευρά (''pleurá'', "side" or "rib"), and κόκκος (''kókkos'', "seed" or "berry"). It is sometimes also called ''Protococcus''. Its taxonomic status needs reinvestigation, since the type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ...
