Abstract |
Emergence of azole resistantAspergillus fumigatushas become a clinical problem in many parts of the world. Several amino acid mutations in the azole target protein, Cyp51Ap, contribute to this resistance, with the most concerning being the environmentally-derived TR34/L98H and TR46/Y121F/T289A mutations. Here, we performed passive surveillance to assess a sample of theA. fumigatuspopulation in the US for the presence of these mutations. We found 1.4% of those isolates to exhibit elevated MIC via broth microdilution and five of those isolates harbored the TR34/L98H mutation. |
