Article Synopsis
- The study aimed to standardize qPCR procedures for diagnosing Mucorales by examining factors that influence DNA extraction and PCR amplification efficiency.
- Two panels of samples were distributed to 26 laboratories, and results showed that using larger serum volumes for DNA extraction and larger input volumes for PCR significantly improved detection sensitivity.
- Findings highlight the importance of optimizing laboratory techniques to enhance diagnosis of Mucormycosis, a serious fungal infection, which is critical for timely treatment in vulnerable patients.
This study investigates the diagnostic practices for mucormycosis among 30 French University Hospital mycology laboratories, in 2024. All laboratories perform both direct examination and culture, with fluorescent brighteners being the most commonly used method for direct examination. While 77 % of the participating laboratories routinely identify Mucorales to the species level, with 70 % having adopted Mucorales-specific quantitative PCR, primarily for the diagnosis of invasive fungal infections.

- Mucormycosis, a severe fungal infection highlighted by the WHO, was studied in France from 2012 to 2022, revealing significant trends in epidemiology and mortality factors.
- Out of 550 cases, key underlying conditions included hematological malignancies (65.1%), with pulmonary infections most common (52.4%) and substantial seasonal variations suggesting more cases in autumn.
- The study linked the rise in PCR diagnostic methods to improved patient outcomes, highlighting that age, ICU diagnosis, and hematological malignancies increased mortality, while diagnosis after 2015 and surgical interventions decreased it.
A commercial loop-mediated isothermal amplification (LAMP) assay is available for the detection of Pneumocytis jirovecii (Eazyplex®, Amplex diagnostics, Germany). Few centers currently use this LAMP assay in France. Recently, the commercialization of reagents used to perform the P.

- The study investigates allergic bronchopulmonary mycoses (ABPM) in patients with cystic fibrosis, focusing on specific IgE responses to five non-Aspergillus molds.
- Researchers analyzed serum samples from 238 patients across several European countries, finding higher levels of specific IgE in these patients compared to healthy controls.
- The findings highlight the need for improved diagnostic tools for ABPM, as several cases were identified using a new scoring system, emphasizing the importance of non-A. fumigatus molds in these conditions.
