Azole resistance in Aspergillus fumigatus: a side-effect of environmental fungicide use?

Open access

Abstract

Invasive aspergillosis due to multi-azole-resistant Aspergillus fumigatus has emerged in the Netherlands since 1999, with 6.0-12.8% of patients harbouring resistant isolates. The presence of a single resistance mechanism (denoted by TR/L98H), which consists of a substitution at codon 98 of cyp51A and a 34-bp tandem repeat in the gene-promoter region, was found in over 90% of clinical A fumigatus isolates. This is consistent with a route of resistance development through exposure to azole compounds in the environment. Indeed, TR/L98H A fumigatus isolates were cultured from soil and compost, were shown to be cross-resistant to azole fungicides, and genetically related to clinical resistant isolates. Azoles are abundantly used in the environment and the presence of A fumigatus resistant to medical triazoles is a major challenge because of the possibility of worldwide spread of resistant isolates. Reports of TR/L98H in other European countries indicate that resistance might already be spreading.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
