Coccidioidomycosis
Coccidioidomycosis (, ), commonly known as cocci, Valley fever, as well as California fever, desert rheumatism, or San Joaquin Valley fever, is a mammalian fungal disease caused by '' Coccidioides immitis'' or '' Coccidioides posadasii''. Coccidioidomycosis is endemic in certain parts of the United States in Arizona, California, Nevada, New Mexico, Texas, Utah, and northern Mexico. ''C. immitis'' is a dimorphic saprophytic fungus that grows as a mycelium in the soil and produces a spherule form in the host organism. It resides in the soil in certain parts of the southwestern United States, most notably in California and Arizona. It is also commonly found in northern Mexico, and parts of Central and South America. ''C. immitis'' is dormant during long dry spells, then develops as a mold with long filaments that break off into airborne spores when it rains. The spores, known as arthroconidia, are swept into the air by disruption of the soil, such as during construction, farm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coccidioides Immitis
''Coccidioides immitis'' is a pathogenic fungus that resides in the soil in certain parts of the southwestern United States, northern Mexico, and a few other areas in the Western Hemisphere. Epidemiology ''C. immitis'', along with its relative '' C. posadasii'', is most commonly seen in the desert regions of the southwestern United States, including certain areas of Arizona, California, New Mexico, Nevada, Texas, and Utah; and in Central and South America in Argentina, Brazil, Colombia, Guatemala, Honduras, Mexico, Nicaragua, Paraguay, and Venezuela. Precise location ''C. immitis'' is largely found in California, but also Baja California and Arizona, while ''C. posadasii'' is regularly found in Texas, northern Mexico and in Central and South America. Both ''C. immitis'' and ''C. posadasii'' are present in Arizona.Hospenthal, Duane R., and Michael G. Rinaldi. Diagnosis and Treatment of Human Mycoses. Totowa, N.J.: Humana Press, 2007, p. 296-297.

Coccidioides Posadasii
''Coccidioides posadasii'' is a pathogenic fungus that, along with ''Coccidioides immitis'', is the causative agent of coccidioidomycosis, or valley fever in humans. It resides in the soil in certain parts of the Southwestern United States, northern Mexico, and some other areas in the Americas, but its evolution was connected to its animal hosts. ''C. posadasii'' and ''C. immitis'' are morphologically identical, but genetically and epidemiologically distinct. ''C. posadasii'' was identified as a separate species other than ''C. immitis'' in 2002 after a phylogenetic analysis. The two species can be distinguished by DNA polymorphisms and different rates of growth in the presence of high salt concentrations: ''C. posadasii'' grows more slowly. It also differs epidemiologically, since it is found outside the San Joaquin Valley. Unlike ''C. immitis'', which is geographically largely limited to California, ''C. posadasii'' can also be found in northern Mexico and South America. Ear ...

Coccidioides
''Coccidioides'' is a genus of dimorphic ascomycetes in the family Onygenaceae. Member species are the cause of coccidioidomycosis, also known as San Joaquin Valley fever, an infectious fungal disease largely confined to the Western Hemisphere and endemic in the Southwestern United States. The host acquires the disease by respiratory inhalation of spores disseminated in their natural habitat. The causative agents of coccidioidomycosis are ''Coccidioides immitis'' and ''Coccidioides posadasii''. Both ''C. immitis'' and ''C. posadasii'' are indistinguishable during laboratory testing and commonly referred in literature as ''Coccidioides''. Clinical presentation Coccidioidomycosis is amazingly diverse in terms of its scope of clinical presentation, as well as clinical severity. About 60% of ''Coccidioides'' infections as determined by serologic conversion are asymptomatic. The most common clinical syndrome in the other 40% of infected patients is an acute respiratory il ...

Mycosis
Fungal infection, also known as mycosis, is disease caused by fungi. Different types are traditionally divided according to the part of the body affected; superficial, subcutaneous, and systemic. Superficial fungal infections include common tinea of the skin, such as tinea of the body, groin, hands, feet and beard, and yeast infections such as pityriasis versicolor. Subcutaneous types include eumycetoma and chromoblastomycosis, which generally affect tissues in and beneath the skin. Systemic fungal infections are more serious and include cryptococcosis, histoplasmosis, pneumocystis pneumonia, aspergillosis and mucormycosis. Signs and symptoms range widely. There is usually a rash with superficial infection. Fungal infection within the skin or under the skin may present with a lump and skin changes. Pneumonia-like symptoms or meningitis may occur with a deeper or systemic infection. Fungi are everywhere, but only some cause disease. Fungal infection occurs after spores a ...

Primary Pulmonary Coccidioidomycosis
Primary pulmonary coccidioidomycosis is an infection caused by inhalation of Coccidioides immitis. Once pulmonary symptoms subside, about 30% of women and 15% of men will have allergic skin manifestations in the form of erythema nodosum. A coccidioidoma is a benign localized residual granulomatous lesion or scar that can remain in the lung's tissues following primary pulmonary coccidioidomycosis.

Itraconazole
Itraconazole, sometimes abbreviated ITZ, is an antifungal medication used to treat a number of fungal infections. This includes aspergillosis, blastomycosis, coccidioidomycosis, histoplasmosis, and paracoccidioidomycosis. It may be given by mouth or intravenously. Common side effects include nausea, diarrhea, abdominal pain, rash, and headache. Severe side effects may include liver problems, heart failure, Stevens–Johnson syndrome and allergic reactions including anaphylaxis. It is unclear if use during pregnancy or breastfeeding is safe. It is in the triazole family of medications. It stops fungal growth by affecting the cell membrane or affecting their metabolism. Itraconazole was patented in 1978 and approved for medical use in the United States in 1992. It is on the World Health Organization's List of Essential Medicines. Recent research works suggest itraconazole (ITZ) could also be used in the treatment of cancer by inhibiting the hedgehog pathway in a similar way t ...

Amphotericin B
Amphotericin B is an antifungal medication used for serious fungal infections and leishmaniasis. The fungal infections it is used to treat include mucormycosis, aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, and cryptococcosis. For certain infections it is given with flucytosine. It is typically given intravenously (injection into a vein). Common side effects include a reaction with fever, chills, and headaches soon after the medication is given, as well as kidney problems. Allergic symptoms including anaphylaxis may occur. Other serious side effects include low blood potassium and myocarditis (inflammation of the heart). It appears to be relatively safe in pregnancy. There is a lipid formulation that has a lower risk of side effects. It is in the polyene class of medications and works in part by interfering with the cell membrane of the fungus. Amphotericin B was isolated from '' Streptomyces nodosus'' in 1955 at the Squibb For Medical Research Institute from c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthroconidia
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. 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 ( ; ), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Community Acquired Pneumonia
Community-acquired pneumonia (CAP) refers to pneumonia (any of several lung diseases) contracted by a person outside of the healthcare system. In contrast, hospital-acquired pneumonia (HAP) is seen in patients who have recently visited a hospital or who live in long-term care facilities. CAP is common, affecting people of all ages, and its symptoms occur as a result of oxygen-absorbing areas of the lung (alveoli) filling with fluid. This inhibits lung function, causing dyspnea, fever, chest pains and cough. CAP, the most common type of pneumonia, is a leading cause of illness and death worldwide. Its causes include bacteria, viruses, fungi and parasites. CAP is diagnosed by assessing symptoms, performing a physical examination, by x-ray or by sputum examination. Patients with CAP sometimes require hospitalization, and it is treated primarily with antibiotics, antipyretics and cough medicine. Some forms of CAP can be prevented by vaccination and by abstaining from tobacco products. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spherule
A sphere () is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the centre of the sphere, and is the sphere's radius. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubbles such as soap bubbles take a spherical shape in equilibrium. The Earth is often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres roll smoothly in any direction, so most balls used in sports and toys are spherical, as are ball bearings. Basic terminology As mentioned earlier is the sp ...
