Candida Tropicalis
''Candida tropicalis'' is a species of yeast in the genus '' Candida''. It is a common pathogen in neutropenic hosts, in whom it may spread through the bloodstream to peripheral organs. For invasive disease, treatments include amphotericin B, echinocandins, or extended-spectrum triazole antifungals. History and taxonomy In the history of fungi, the name of genus ''Candida'', derived from the family Debaryomycetaceae, comes from the Latin term "" which has the meaning of “glowing white” and also refers to as smooth and glistering. Genus ''Candida'' referred to any asexual yeast without any of the following characteristics: production of acetic acid, pigments of colours red, pink or orange, arthroconidia, unipolar or bipolar budding, enteroblastic-basipetal budding, blastoconidia formation on sympodulae, buds formation on stalks, triangular cells, needle-shaped terminal conidia, and having the ability to grow on inositol as a sole carbon source.

Aldo Castellani
Aldo Castellani, KCMG (8 September 1874 – 3 October 1971) was an Italian pathologist and bacteriologist. Life and achievements Castellani was born in Florence and educated there, qualifying in medicine in 1899. He worked for a time in Bonn and joined the School of Hygiene and Tropical Medicine in London in 1901. As bacteriologist with the Royal Society Commission on Sleeping Sickness in 1902, he went to Entebbe, Uganda with George Carmichael Low and Cuthbert Christy. He demonstrated the cause and means of transmission of sleeping sickness, discovered the spirochete of yaws, and did other original work in bacteriology and in parasitic diseases of the skin. In 1903 he was appointed Bacteriologist to the Government of Ceylon at the Central laboratory in Colombo and continued research in mycology and bacteriology, describing several new species of intestinal bacilli.

Conidia
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an asexual, non- motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' '' Metarhizium'') species. The terms microconidia and macroconidia are sometimes used. Conidiogenesis There are two main types of coni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabouraud Agar
Sabouraud agar or Sabouraud dextrose agar (SDA) is a type of agar growth medium containing peptones. It is used to cultivate dermatophytes and other types of fungi, and can also grow filamentous bacteria such as '' Nocardia''. It has utility for research and clinical care. It was created by, and is named after, Raymond Sabouraud in 1892. In 1977 the formulation was adjusted by Chester W. Emmons when the pH level was brought closer to the neutral range and the dextrose concentration lowered to support the growth of other microorganisms. The acidic pH (5.6) of traditional Sabouraud agar inhibits bacterial growth. Typical composition Sabouraud agar is commercially available and typically contains:University of Sydney''Recipes'' * 40 g/L dextrose * 10 g/L peptone * 20 g/L agar * pH 5.6 Medical Use Clinical laboratories can use this growth medium to diagnose and further speciate fungal infections, allowing medical professionals to provide appropriate treatment with antifun ...

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. T ...

Blastoconidium
A blastoconidium (plural blastoconidia) is an asexual holoblastic conidia formed through the blowing out or budding process of a yeast cell, which is a type of asexual reproduction that results in a bud arising from a parent cell. The production of a blastoconidium can occur along a true hyphae, pseudohyphae, or a singular yeast cell. The word "conidia" comes from the Greek word ''konis'' and ''eidos, konis'' meaning dust and ''eidos'' meaning like. The term "bud" comes from the Greek word ''blastos,'' which means bud. Yeasts such as ''Candida albicans'' and ''Cryptococcus neoformans'' produce these budded cells known as blastoconidia. Formation of a blastoconidium The mitotic budding process through which blastoconidia are formed consists of three steps. The first step is bud emergence, in which the outer cell wall of the parental yeast thins. At the same time, there is growth of new cell wall and plasma membrane components. The next step is bud growth, a process that is regulat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a 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 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 * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscu ...

Budding
Budding or blastogenesis is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. For example, the small bulb-like projection coming out from the yeast cell is known as a bud. Since the reproduction is asexual, the newly created organism is a clone and excepting mutations is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals. Internal budding or endodyogeny is a process of asexual reproduction, favored by parasites such as '' Toxoplasma gondii''. It involves an unusual process in which two daughter cells are produced inside a mother cell, which is then consumed by the offspring prior to their ...
