The protein kinases family in fungi: adaptability, virulence and conservation between species

mycolabadmin

Protein kinases are cellular ‘switches’ that help fungi survive harsh conditions by regulating how cells make proteins and adapt to stress. A particularly important kinase called GCN2 acts as a sensor that detects when fungi lack amino acids, triggering a survival response that helps the fungus adapt and maintain pathogenicity. This review shows how understanding GCN2 could help scientists develop new antifungal drugs to treat fungal infections.

Identification of Non-fumigatus Aspergillus Species in Clinical Samples from Southern California

mycolabadmin

Researchers in Southern California studied fungal infections caused by Aspergillus, a common mold that can infect humans. They found that species other than the traditionally dangerous A. fumigatus are now being detected more frequently in patient samples, particularly from skin and respiratory infections. These non-fumigatus species showed interesting seasonal patterns and some may be resistant to standard antifungal treatments, suggesting doctors may need to adjust their treatment strategies.

Invasive Fungal Disease is Rare in Multiple Myeloma Patients Treated with BCMA CAR-T Therapy

mycolabadmin

Researchers studied patients with multiple myeloma who received a new type of cancer treatment called BCMA CAR-T cell therapy. While this powerful therapy can sometimes increase infection risk, the study found that serious fungal infections occurred in only a small percentage of patients (1.7%). However, when these fungal infections did occur, they were often severe and potentially life-threatening, particularly in patients who experienced significant side effects from the therapy.

Mixed Infection With Aspergillosis and Actinomycosis in the Maxillary Sinus: A Case Report

A 74-year-old woman had a purulent nasal discharge for 1.5 years caused by two different infections occurring simultaneously in her maxillary sinus: aspergillosis (a fungal infection) and actinomycosis (a bacterial infection). Imaging initially suggested only a fungal ball, but pathological examination revealed both organisms were present. The patient was successfully treated with surgical removal of the infected material followed by antibiotic therapy.

Fungal β-Glucans: Biological Properties, Immunomodulatory Effects, Diagnostic and Therapeutic Applications

mycolabadmin

β-glucans are natural substances found in yeast and fungi that help boost the immune system and fight cancer. They can be measured in blood to diagnose serious fungal infections and may help prevent common illnesses like colds and respiratory infections. Recent research suggests they could be useful additions to vaccines and may help patients recovering from COVID-19.

Stonebrood Disease—Histomorphological Changes in Honey Bee Larvae (Apis mellifera) Experimentally Infected with Aspergillus flavus

mycolabadmin

Researchers studied how a rare fungal disease called stonebrood affects honey bee larvae by infecting them with the fungus Aspergillus flavus. They found that the fungus establishes in the bee’s gut within 24 hours and kills the larvae within two days, likely through production of toxic compounds. The study reveals three stages of infection progression and highlights why beekeepers need protection when handling infected colonies.

Co-transformation of Aspergillus fumigatus: a simple and efficient strategy for gene editing without linking selectable markers

mycolabadmin

Scientists have developed a new technique for editing genes in a dangerous fungal pathogen called Aspergillus fumigatus. Instead of permanently attaching antibiotic resistance markers to the target genes (which can interfere with normal gene function), they use a clever strategy of introducing two different DNA pieces simultaneously. One piece makes the desired gene edit while the second introduces a resistance marker to a completely different location in the genome. This approach is simple, inexpensive, and works about 11% of the time, making it practical for identifying successfully edited strains.

One for All and All for One: Multikingdom Interplay in Severe Viral Pneumonia

mycolabadmin

This editorial discusses how bacteria, viruses, and fungi interact in the lungs during severe pneumonia from COVID-19 or influenza. When mechanically ventilated patients with COVID-19 had bacterial infections detected, their immune systems released more inflammatory chemicals. However, the same pattern was not observed in influenza patients. Understanding how all these microorganisms work together may help doctors better treat these serious lung infections.

Unlocking the potential of experimental evolution to study drug resistance in pathogenic fungi

mycolabadmin

Fungal infections are becoming harder to treat as fungi develop resistance to antifungal drugs. This review explains how scientists can use experimental evolution—growing fungi in controlled laboratory conditions while exposing them to drugs—to understand how and why resistance develops. By studying these evolutionary processes and using mathematical models to predict outcomes, researchers can develop better treatment strategies, including combination therapies and drug cycling approaches to prevent resistance from emerging.

mSphere of Influence: Population-level thinking to unravel microbial pathogenicity

mycolabadmin

This article discusses how scientists have traditionally divided fungi into clear categories of disease-causing pathogens versus harmless non-pathogens, often based on studying just one strain. Recent research shows that non-pathogenic fungi can actually have many disease-causing traits similar to pathogenic species, suggesting the boundary between dangerous and safe fungi is not as clear-cut as previously thought. By studying many different strains across species, researchers can better understand how fungal diseases develop and potentially evolve.
