organisms are best highlighted by staining the cell wall with silver stains such as GMS or PAS stain.
(7) Fungal causes of mandibular osteomyelitis are rare, and that caused by Blastomyces
are not well-described in the literature.
Hamilton and colleagues used monoclonal antibodies screening cross-reactivity to dimorphic fungi with similar antigens, as Histoplasma, Blastomyces
, Sporothrix and Paracoccidioides species.
For instance, Blastomyces
can cause vertebral body collapse and the gibbus deformity like tuberculosis, and can be distinguished from tuberculosis by the presence of lesions in adjacent ribs.
Common fungi causing conjunctivitis are: Candida albicans, Candida parapsilosis, Candida tropicalis, Paracoccidioides brasiliensis, Coccidioides immitis, Blastomyces
dermatitidis, Rhinosporidium seeberi, Sporothrix schenckii, etc.
In vitro activities of voriconazole, itraconazole, and amphotericin B against Blastomyces
dermatitidis, Coccidioides immitis, and Histoplasma capsulatum.
Se ha demostrado que la pared de las celulas levaduriformes en hongos dimorficos como Blastomyces
dermatitidis, Histoplasma capsulatum y P brasiliensis contienen predominantemente [alfa]-glucano y solamente pequenas cantidades de [beta]-glucano, mientras que el [beta]-glucano es abundante en la fase micelial (19).
A PCR assay performed for aspergillus, histoplasmosis and blastomyces
was also sent and was negative.
Blastomycosis is a fungal infection which is caused by Blastomyces
dermatitidis and is especially endemic in areas of the United States with a moist climate, i.e.
is a fungus endemic to the Ohio and Mississippi river valleys that enters the lungs and then the blood stream, where the organism is able to disseminate throughout the body.
