Abstract:
We hereby report two instances of dimorphic fungus cultivation in BacT/ALERT-based bacteriologic media, with the first such characterization of Blastomyces dermatitidis. From a patient with disseminated coccidioidomycosis, routine blood cultures incubated on the MB/BacT 3D Microbial Detection System generated a positive signal following 75 h of incubation. B. dermatitidis was isolated from a patient hospitalized with a four-week course of respiratory illness. Organism detection from respiratory specimens via the MB/BacT 3D Mycobacteria Detection System occurred 5 days sooner than the routine fungus culture. Etiologic agents of endemic mycoses may be isolated in bacteriologic media employed by continuous monitoring instrumentation.
