MY1704-3

Sputum: Rhizopus species – Shipped April 03, 2017

HISTORY

This challenge was sent as a simulated sputum sample obtained from a diabetic patient with pneumonia. Laboratories were expected to isolate and identify Rhizopus species.

MAIN EDUCATIONAL POINTS from MY1704-3

  • Rhizopus species have the rhizoids located at the point where the stolons and sproangiophores meet. This is unlike Rhizomucor and Absidia that have stolons between the rhizoids and not opposite them.
  • In patients with any of the predisposing conditions, the isolation of any Zygomycete fungus should be regarded as potentially significant.
