Disease: antifungal-resistant infections

High‐Throughput Culture and DNA Isolation Methods for Aspergillus fumigatus

mycolabadmin

Scientists have developed a faster, cheaper way to grow and extract DNA from Aspergillus fumigatus, a fungus that causes serious infections in sick people. Using 96-well plates (the same format used in many laboratories), researchers can now process many samples at once instead of handling them one by one. The method works well for identifying drug-resistant fungal strains and preparing DNA for genetic analysis.

Investigation of the antifungal activity of panobinostat, tamoxifen, and miltefosine alone and in combination with some conventional antifungal drugs against fluconazole-resistant Candida species

mycolabadmin

Researchers tested whether three cancer drugs (panobinostat, tamoxifen, and miltefosine) could enhance the effectiveness of common antifungal medications against drug-resistant yeast infections. When combined with antifungals, some of these cancer drugs showed promise in killing resistant Candida species, though the effectiveness varied depending on which type of yeast was being treated. These findings suggest that combination therapies using already-approved drugs could help treat difficult fungal infections in cancer patients.

Diagnostic Performance of a PCR-Based Approach for the Diagnosis of Dermatomycosis

mycolabadmin

This study evaluated a new testing method combining DNA analysis (PCR) with traditional microscopy and culture to diagnose fungal skin, hair, and nail infections. The PCR method detects the infection quickly and accurately, identifying the specific fungus causing the problem within days rather than weeks. The study of over 4,400 samples found that Trichophyton rubrum was the most common cause of fungal infections, and the combined testing approach was 98.5% accurate while reducing unnecessary lab work.

Speciation analysis of fungi by liquid atmospheric pressure MALDI mass spectrometry

mycolabadmin

Scientists developed a fast new method using a technique called LAP-MALDI mass spectrometry to identify dangerous fungal infections within minutes instead of days. The method analyzes the unique fatty acids and proteins in fungal cells to distinguish between different species. This could help doctors quickly identify which fungal infection a patient has and choose the right treatment, potentially saving lives.

New approaches to tackle a rising problem: Large-scale methods to study antifungal resistance

mycolabadmin

Fungal infections are becoming increasingly resistant to antifungal drugs, creating a serious public health challenge. Scientists are using advanced genetic sequencing and laboratory techniques to understand how fungi develop drug resistance and identify the specific genetic changes responsible. By cataloging resistance mutations and creating shared databases, researchers aim to develop better diagnostic tests and treatment strategies to combat these dangerous infections.
