Blastomyces dermatitidis and Blastomycosis

BLASTOMYCOSIS Kingdom: Fungi Phylum: Ascomycota Class: Euascomycetes Order: Onygenales Family: Onygenaceae Genus: Blastomyces (Blastomyces dermatitidis is the only species include in this genus.) Blastomycosis, to a fault called Gilchrists Disease, is caused by Blastomyces dermatitidis. This fungus is thermally dimorphic and a probable saprobe of the soil. It specifically inhabits decaying wood material, animal feces, constitute fragments, and insect remains. Soil with an sharp pH and a soaring organic content is causative to growth. At room temperature and in its natural site in soil, it grows as a m sr.. However, when the spores ar inhaled and environmental temperature is elevated , B. dermatitidis conidia convert over into invasive braggart(a) yeasts. While this is non a super acidality unhealthiness, it does conk sporadically in the US. In the U.S.A., the autochthonous plain for blastomycosis includes the Ohio, Missouri, and manuscript river valleys and Midwestern states bordering the large Lakes. There are estimated 1-2 nerves per 100,000 people in these endemic areas, which all permit soused proximity to waterways. Although a appraise of death records for 2002 indicated blastomycosis was the reported rudimentary cause of death for 44 persons in the United States, epidemiologic patterns for this unhealthiness have not been fully characterized because blastomycosis is not nationally notifiable. It is a reportable disease only in Wisconsin and small, topical anesthetic areas of other states.

fit to the CDC, there is a 5% death rate rate. African-type B. dermatitidis strains isolated from typesetters cases in Africa also exist. It was demonstrated that the African-type strains are not identical to the normality American strains. The disease is transmitted by inhaling spore-laden dust. Person-to-person contagious disease does not occur. It is more common in men who make grow in outdoor occupations (construction, farming, etc.) analysis of information regarding sporadic case reports suggests the risk for disease whitethorn be greater among old (35-55 years)...
