Therefore, the present study was designed to investigate the mechanism of acquired echinocandin resistance in C. parapsilosis complex strains. A total of 15 clinical C. parapsilosis complex isolates were sub-cultured for 30 days at a low concentration of micafungin at ½ the lowest MIC value of the tested isolates (0.12 µg/ml).

Diagnosis and management of IFIs becomes progressively challenging, with increasing antifungal resistance and the emergence of rare fungal species. Through a consensus survey focused on assessing current views on how IFI should be managed, the aim of this project was to identify challenges around diagnosing and managing IFIs in the ICU.

These were used to develop an online survey which was distributed on a convenience sampling basis utilising the subscriber list held by an independent provider (M3 Global).

This study employed pathogen whole-genome sequencing to investigate the epidemiology and drug-resistance mutations of <i>C. auris</i> using 16 strains isolated from two patients.

Despite low genetic variability among patient isolates, notable mutations were identified, including Y132F in <i>ERG11</i> and A585S in <i>TAC1b</i>, likely linked to increased fluconazole resistance. Strains from patient B also carried F214L in <i>TAC1</i>b, resulting in a consistent voriconazole minimum inhibitory concentration of 4 µg/mL across all isolates. Furthermore, a novel frameshift mutation in the <i>SNG1</i> gene was observed in amphotericin B-resistant isolates compared to susceptible ones. Our findings suggest the potential transmission of <i>C. auris</i> and emphasize the need to explore variations related to antifungal resistance.
