Multi-azole-resistant Aspergillus fumigatus in the environment in Tanzania.

Objectives: Azole resistance in Aspergillus fumigatus isolates has been increasingly reported with variable prevalence worldwide and is challenging the effective management of aspergillosis. Here we report the coexistence of both TR₃₄/L98H and TR₄₆/Y121F/T289A resistance mechanisms in azole-resistant A. fumigatus (ARAF) isolates originating from Tanzania, Africa.
