Blastomyces dermatitidis and Blastomycosis

BLASTOMYCOSIS Kingdom: Fungi Phylum: Ascomycota Class: Euascomycetes night club: Onygenales Family: Onygenaceae Genus: Blastomyces (Blastomyces dermatitidis is the only species included in this genus.) Blastomycosis, also 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, plant fragments, and insect remains. Soil with an rancor pH and a high organic content is conducive to growth. At room temperature and in its natural site in soil, it grows as a mold. However, when the spores be inhaled and environmental temperature is elevated , B. dermatitidis conidia counterchange over into invasive large yeasts. While this is non a common complaint, it does conk sporadically in the US. In the U.S.A., the endemical atomic number 18a for blastomycosis includes the Ohio, Missouri, and manuscript river valleys and Midwestern states border ing the Great Lakes. There are estimated 1-2 nerves per 100,000 people in these endemic areas, which all admit close proximity to waterways. Although a review of death records for 2002 indicated blastomycosis was the report underlying cause of death for 44 persons in the linked States, epidemiologic patterns for this disease have not been fully characterized because blastomycosis is not nationally notifiable. It is a reportable disease only in Wisconsin and small, local areas of other states.

fit to the CDC, there is a 5% mortality rate. African-type B. dermatitidis strains isolated from cases in Africa also exist. It was demonstrated that the African-type strains are not identical t o the normality American strains. The dise! ase is transmittable by inhaling spore-laden dust. Person-to-person contagious disease does not occur. It is much common in men who produce in exterior occupations (construction, farming, etc.) Analysis of information regarding sporadic case reports suggests the risk for disease may be greater among old (35-55 years)...
