Ciri dan struktur
Blastomyces dermatitidis is the causal agent of blastomycosis, a potentially very serious disease that typically begins with a characteristically subtle pneumonia-like infection that may progress, after 1–6 months, to a disseminated phase that causes lesions to form in capillary beds throughout the body, most notably the skin, internal organs, central nervous system and bone marrow. The sexual form of this fungus was formerly known as Ajellomyces dermatitidis. In 2013, a second species was described in the genus Blastomyces, B. gilchristii, which subsumes certain strains previously assigned to B. dermatitidis. Three more species have been described: Blastomyces emzantsi, Blastomyces parvus and Blastomyces percursus. Along with two other important human-pathogenic fungi, Histoplasma capsulatum andParacoccidioides brasiliensis, species of Blastomyces belong to the family Ajellomycetaceae. The three principal pathogens in this family are all grouped physiologically as "dimorphic fungi": fungi that switch from a mold-like (filamentous) growth form in the natural habitat to a yeast-like growth form in the warm-blooded animal host. Blastomyces dermatitidis itself is a sexual organism, occurring in nature as both a + mating type and a − mating type. This is epidemiologically important for two reasons: firstly, it implies that the organism will be genetically variable, potentially leading to variations in disease severity, treatment response and habitat preference; secondly, it implies that a suitable, stable habitat must exist for the complex process of sexual reproduction to take place.
Habitat dan peran ekologis
One of the unexplained regularities of nature is that there are several fungi of different phylogenetic ancestry that show a similar pattern of existence: dimorphism (conversion from a filamentous form in the environment to a yeast form in warm-blooded host tissues), virulent pathogenesis (ability to cause a significant infection in an animal host that is otherwise in good health), pulmonary infectivity (infection mainly via the lungs) and sharply delimited endemism (occurrence in only a limited geographic range.). Blastomyces dermatitidis adalah salah satu jamur ini; yang lainnya adalah Histoplasma capsulatum, Paracoccidioides brasiliensis, Coccidioides immitis, C. posadasii dan Talaromyces marneffei. Jarak geografis B. dermatitidis sebagian besar difokuskan di sekitar jalur air St. Lawrence and Mississippi River systems of North America. Ada peta yang tersebar luas dan banyak dipublikasikan kembali, sebagian salah yang menunjukkan U.S. portion dari kisaran ini dengan akurat, termasuk kejadian di Minnesota, Wisconsin, Ohio, Kentucky, Arkansas, Tennessee, North and Carolina Selatan, Virginia, Mississippi, Louisiana, dan beberapa wilayah negara bagian yang bersebelahan dengan yang diberi nama. Canadian range dari B. dermatitidis menunjukkan kelimpahan blastomycosis di daerah luas utara dan selatan St.
