Elizabeth Lee Hazen
Elizabeth Lee Hazen (August 24, 1885 in Mississippi – June 24, 1975) is most known for her contribution to the development of nystatin. Her education focused on science and research where she developed a passion for microbiology. Her peers and teachers knew her as a quick learner and a bright student. In 1948, she teamed up with Rachel Fuller Brown to develop nystatin, the first non-toxic drug treatment for fungal infections in humans. Her research had multiple applications ranging from saving infected trees to restoring paintings and artwork damaged due to mold. Early life Elizabeth Lee Hazen was born on August 24, 1885, in Rich, Mississippi, to William Edgar Hazen and Maggie Harper Hazen. She was their second daughter and middle of three children.Laura Lynn Windsor, ''Women in Medicine: An Encyclopedia'', '' ABC-CLIO'', 2002, pp. 92–93.

Rachel went to Commercial High School, but later switched to Central High School because her mother wanted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Candidiasis
Candidiasis is a fungal infection due to any type of '' Candida'' (a type of yeast). When it affects the mouth, in some countries it is commonly called thrush. Signs and symptoms include white patches on the tongue or other areas of the mouth and throat. Other symptoms may include soreness and problems swallowing. When it affects the vagina, it may be referred to as a yeast infection or thrush. Signs and symptoms include genital itching, burning, and sometimes a white "cottage cheese-like" discharge from the vagina. Yeast infections of the penis are less common and typically present with an itchy rash. Very rarely, yeast infections may become invasive, spreading to other parts of the body. This may result in fevers along with other symptoms depending on the parts involved. More than 20 types of ''Candida'' can cause infection with ''Candida albicans'' being the most common. Infections of the mouth are most common among children less than one month old, the elderly, and those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptococcus Neoformans
''Cryptococcus neoformans'' is an encapsulated yeast belonging to the class Tremellomycetes and an obligate aerobe that can live in both plants and animals. Its teleomorph is a filamentous fungus, formerly referred to ''Filobasidiella neoformans''. In its yeast state, it is often found in bird excrement. ''Cryptococcus neoformans'' can cause disease in apparently immunocompetent, as well as immunocompromised, hosts. Classification ''Cryptococcus neoformans'' has undergone numerous nomenclature revisions since its first description in 1895. It formerly contained two varieties: ''C. neoformans ''var.'' neoformans'' and ''C. neoformans '' var.'' grubii''. A third variety, ''C. neoformans ''var.'' gattii'', was later defined as a distinct species, ''Cryptococcus gattii''. The most recent classification system divides these varieties into seven species. ''C. neoformans'' refers to ''C. neoformans '' var.'' grubii''. A new species name, ''Cryptococcus deneoformans'', is used for the f ...

Candida Albicans
''Candida albicans'' is an opportunistic pathogenic yeast that is a common member of the human gut flora. It can also survive outside the human body. It is detected in the gastrointestinal tract and mouth in 40–60% of healthy adults. It is usually a commensal organism, but it can become pathogenic in immunocompromised individuals under a variety of conditions. It is one of the few species of the genus '' Candida'' that causes the human infection candidiasis, which results from an overgrowth of the fungus. Candidiasis is, for example, often observed in HIV-infected patients. ''C. albicans'' is the most common fungal species isolated from biofilms either formed on (permanent) implanted medical devices or on human tissue. ''C. albicans'', ''C. tropicalis'', ''C. parapsilosis'', and ''C. glabrata'' are together responsible for 50–90% of all cases of candidiasis in humans. A mortality rate of 40% has been reported for patients with systemic candidiasis due to ''C. albicans''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinomycetes
The Actinomycetales is an order of Actinomycetota. A member of the order is often called an actinomycete. Actinomycetales are generally gram-positive and anaerobic and have mycelia in a filamentous and branching growth pattern. Some actinomycetes can form rod- or coccoid-shaped forms, while others can form spores on aerial hyphae. Actinomycetales bacteria can be infected by bacteriophages, which are called actinophages. Actinomycetales can range from harmless bacteria to pathogens with resistance to antibiotics. Reproduction Actinomycetales have 2 main forms of reproduction: spore formation and hyphae fragmentation. During reproduction, Actinomycetales can form conidiophores, sporangiospores, and oidiospores. In reproducing through hyphae fragmentation, the hyphae formed by Actinomycetales can be a fifth to half the size of fungal hyphae, and bear long spore chains. Presence and associations Actinomycetales can be found mostly in soil and decaying organic matter, as well as in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
