Triazole-Resistant Aspergillus fumigatus in an Israeli Patient with Chronic Cavitary Pulmonary Aspergillosis Due to a Novel E306K Substitution in Hmg1.

Triazole resistance in the pathogenic mold Aspergillus fumigatus has increased worldwide, posing a growing therapeutic challenge. Recently, mutations in the 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase gene (hmg1) have been associated with triazole resistance. Here, we describe a novel E306K triazole resistance-conferring mutation in the HMG-CoA reductase gene from an Israeli patient with chronic cavitary pulmonary aspergillosis (CCPA).
