We report the identification of Blastomyces dermatitidis by microscopic examination of a direct faecal smear from a dog with pulmonary blastomycosis. A simultaneously obtained faecal culture grew Blastomyces dermatitidis. The fungus was also cultured from a transtracheal sample from this same dog. This report suggests that yeast-phase cells of B. dermatitidis may be recovered in the stool of do...

Blastomycosis, a fungal infection caused by Blastomyces dermatitidis, was once thought to be endemic only to the Central and Great Lakes regions of the United States of America. We present the first reported case series of patients documenting the diagnosis of blastomycosis in the Pacific region. In both cases, exposure to endemic areas was retrospectively identified. ness of symptoms during cl...

We describe a case of blastomycosis in an 8-year-old boy with Blastomyces-associated osteomyelitis and possible pulmonary involvement. We also identify 309 cases of blastomycosis in Ontario that were seen during a 10-year period, 57% of which occurred from 2001 to 2003. The overall incidence during the study period was 0.30 cases per 100,000 population. Most patients were from north Ontario (n ...

Although antibiotic agents were introduced beginning in the mid-1930's, there was no really useful agent for the treatment of deepseated mycotic infections such as histoplasmosis, cryptococcosis, coccidioidomycosis, and blastomycosis until the introduction of amphotericin B in the late 1950's. The present report will review some of the available information concerning amphotericin B and will pr...

The systemic fungal infection, blastomycosis, which infects both humans and animals has presented a diagnostic challenge for clinicians for many years. The aim of this study was to evaluate the diagnostic sensitivity of Blastomyces dermatitidis yeast lysate antigens with respect to antibody detection in dogs with blastomycosis. Lysate antigens were prepared from B. dermatitidis isolates T-58 an...

Acute respiratory distress syndrome (ARDS) is an uncommon, highly fatal, and poorly understood manifestation of blastomycosis. Optimal management remains unknown, including the roles of adjunctive corticosteroids and extracorporeal membrane oxygenation (ECMO).We conducted a retrospective chart review of patients with ARDS caused by blastomycosis, managed in intensive care units in Manitoba, Can...

Blastomycosis is a disease caused by endemic fungi that ranges from severe pulmonary or disseminated to mild or asymptomatic. Environmental factors associated with it are not well described throughout the endemic area. We used the intramural State Inpatient Database from the Agency for Healthcare Research and Quality and ArcMap GIS to identify geographic high-risk clusters of blastomycosis hosp...

Blastomycosis is a systemic and cutaneous fungal infection of humans, dogs, cats and other animals that has been reported from parts of North America, Africa and India. In most areas the disease occurs predominantly in individuals exposed to rural agricultural, recreational or wilderness environments. The precise ecological niche for Blastomyces dermatitidis remains undefined. In the current wo...

BACKGROUND Cerebral blastomycosis is a rarely reported disease, and in the absence of associated, underlying systemic infection, poses a great diagnostic difficulty. Magnetic resonance imaging can sometimes provide equivocal information when trying to pinpoint a diagnosis. Classically, cerebral blastomycosis has been treated with amphotericin B. Voriconazole is a newer triazole antifungal with ...
