A dimorphic mold (or mould) Emmonsia crescens, Emmonsia parva, Emmonsia pasteuriana.
Most cases are in South Africa. The fungus is worldwide, a rat (and other mammals) pathogen, that causes Adiaspiromycosis.
"Recently, the susceptibility of an isolate of E. crescens to various antifungal agents was determined (5). The MICs (in μg/ml) of amphotericin B, itraconazole, voriconazole, caspofungin, fluconazole, and 5-fluorocytosine were 0.06, 0.12 to 0.25, 0.06, 0.5, 64, and 8, respectively, with no significant differences in susceptibilities between the aleurioconidia and adiaspores. Only amphotericin B was fungicidal (PubMed)".
In one case series, amphotericin treatment was most associated with survival (PubMed).
Can cause a positive urine histoplasma antigen.
