Fungal Genomics in Respiratory Medicine: What, How and When?

Area of Science:

• Medical Mycology
• Infectious Diseases
• Genomics

Background:

• Fungal respiratory infections pose a significant threat, particularly to immunocompromised individuals.
• Coronavirus disease-19 (COVID-19) increases susceptibility to secondary fungal co-infections, such as aspergillosis and mucormycosis.
• Emerging azole resistance in Aspergillus fumigatus complicates treatment and elevates mortality risks.

Purpose of the Study:

• To review current molecular diagnostic techniques for respiratory fungal pathogens.
• To explain the mechanisms and applications of these diagnostic methods.
• To highlight the importance of early detection for patient survival.

Main Methods:

• Review of available molecular diagnostic techniques.
• Explanation of genomic-based diagnostic principles.
• Discussion of clinical applications and case examples.

Main Results:

• Molecular diagnostics provide a fast, reproducible, and cost-effective alternative to traditional culture-based methods.
• These techniques enable early identification of fungal pathogens and detection of antifungal resistance.
• Genomic advances facilitate timely and accurate diagnosis, crucial for managing co-infections in vulnerable patients.

Conclusions:

• Molecular diagnostics are essential for the rapid and accurate diagnosis of fungal respiratory infections.
• Early detection of fungal pathogens and antifungal resistance improves patient outcomes, especially in the context of COVID-19.
• Advancements in fungal genomics are transforming diagnostic capabilities in clinical settings.
