MAIN EDUCATIONAL POINTS from 1101-4
- Only one case of sinusitis associated with Malbranchea has ever been reported. The significance of Malbranchea is that it is similar microscopically to Coccidioides.
- Unlike Coccidioides immitis, Malbranchea does not produce spherules containing endospores, it is negative for C. immitis exoantigen test and/or DNA test probe.
