- Includes Aureobasidium pullulans
- One of the black yeasts
- May contaminate metal, hardware in hospitals, commonly found as contaminants in clinical laboratories
Clinical Presentation
- Has previously been found in peritoneal dialysis catheters
- In severely compromised patients deep infections have been described, including blood, BAL, lymph nodes, splenic abscess or CSF
Diagnosis
- Culture
- Colony: looks like a black yeast on culture
- Microscopy:
- Septate, hyaline hyphae becoming dark brown with age
- Synchronous conidia (3 at a time) from irregular hyphae
- DNA sequencing can identify it further
Management
- No standard treatment but amphotericin B is recommended
- Some other sources quote fluconazole/flucytosine as possible agents
