Wound: Scedosporium species – Shipped April 2013
This sample was sent as a simulated wound swab obtained from a patient with an ankle ulcer.
MAIN EDUCATIONAL POINTS from MY1304-3
- If only the asexual state is seen, the report should indicate that the isolate is Scedosporium species, other than S. prolificans, as phenotypic tests are not reliable to yield a clear identification; molecular characterization is required for definitive identification of the anamorph.
- Diseases in humans are caused predominantly by S. apiospermum and S. prolificans.
- Differentiation between S. boydii and S. apiospermum is clinically irrelevant. Therefore, incubating a culture for a couple of weeks to promote cleistothecia, confirming the Pseudoallescheria boydii complex identification, is not recommended.
