Abstract

In this study, 1717 fungal clinical isolates causing invasive fungal infections were evaluated against nine antifungal agents using Clinical and Laboratory Standards Institute (CLSI) reference broth microdilution methods. The isolates comprised 1487 Candida spp., 109 Aspergillus spp., 86 non-Candida yeasts (including 52 isolates of Cryptococcus neoformans) and 35 rare moulds obtained during 2012 from 72 hospitals worldwide. Echinocandin resistance among Candida spp. was low, and resistance rates to anidulafungin, caspofungin and micafungin varied from 0.0% to 2.8% among different species. Echinocandin-resistant Candida glabrata were shown to have fks mutations (fks2 HS1 F659Y, F659del, S663F and S663P), and fluconazole resistance was also observed in those strains. One Candida krusei and one Candida dubliniensis had L701M or S645P fks1 mutations, respectively. Candida tropicalis and C. glabrata had higher fluconazole resistance rates of 6.1% and 6.9%, respectively, compared with other Candida spp. Fluconazole-resistant C. tropicalis were collected in five countries (USA, China, Germany, Belgium and Thailand). Voriconazole was active against all Candida spp., inhibiting 91.2-99.7% of isolates using species-specific breakpoints. All agents except for the echinocandins and posaconazole were active against Cr. neoformans. Triazoles were active against other yeasts [MIC90 (minimum inhibitory concentration encompassing 90% of isolates tested), 2μg/mL]. The echinocandins and the mould-active triazoles were active against Aspergillus [MIC/MEC90 (minimum effective concentration encompassing 90% of isolates tested) range, 0.015-2μg/mL], but the activity of these agents was limited against uncommon mould species (MIC/MEC90 range, 4μg/mL to >16μg/mL).

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Species-specific data from a broadly representative population have been lacking.

    “While several studies using larger cohorts to study illness and outcomes exist [11, 15–17], species-specific data from a broadly representative population have been lacking”

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.
