The emerging fungal pathogen Cryptococcus gattii: Epidemiology, pathogenesis, immunomodulatory attributes, and drug susceptibility

mycolabadmin

Cryptococcus gattii is a dangerous fungal infection that can affect even healthy people, unlike most fungal infections that target those with weak immune systems. The fungus uses clever tricks to hide from the immune system, including creating protective capsules and producing melanin. Current antifungal drugs like fluconazole are becoming less effective as the fungus develops resistance, making this an urgent public health concern that requires better treatments and early detection.

What Do We Know About Cryptococcus spp. in Portugal? One Health Systematic Review in a Comprehensive 13-Year Retrospective Study (2013–2025)

mycolabadmin

This study examines cryptococcosis, a fungal infection that affects both animals and humans, across Portugal from 2013-2025. Researchers found that about 4.5% of animal samples tested positive for Cryptococcus species, with infections most common in dogs and cats. The infections peaked during summer months and were most prevalent in central Portugal, with different fungal species affecting different animal types. The research emphasizes the importance of coordinated monitoring across animals, humans, and the environment to better understand and control this disease.

Addressing Critical Fungal Pathogens Under a One Health Perspective: Key Insights from the Portuguese Association of Medical Mycology

Four dangerous fungal species pose growing threats to human health worldwide, especially for people with weakened immune systems. Portugal’s medical experts have reviewed the current situation, finding these fungi increasingly resistant to treatment, present in hospitals and the environment, and occasionally spreading from animals to people. The review emphasizes the need for better testing, coordinated tracking systems, and approaches that consider human, animal, and environmental health together to combat this emerging crisis.

Emerging Infections Network Survey of Screening for Cryptococcal Antigenemia, United States, 2024

mycolabadmin

Researchers surveyed infectious disease doctors across the United States about their use of a blood test (cryptococcal antigen screening) to detect a serious fungal infection in HIV patients before symptoms appear. Only about one-third to two-thirds of doctors regularly perform this inexpensive and accurate test, depending on the patient’s immune system status. Many doctors were unsure about the benefits and guidelines for this screening, suggesting that education and clearer guidelines could help more patients catch this dangerous infection early and receive treatment before it becomes life-threatening.

Naganishia albidus Causing Perioral Cutaneous Infection: A Rare Case Easily Misdiagnosed

mycolabadmin

A 37-year-old man developed an unusual fungal skin infection around his mouth caused by Naganishia albidus, a rare yeast. He was initially misdiagnosed with eczema and his condition worsened with wrong treatment. Advanced fungal testing techniques helped identify the correct organism, and after six weeks of antifungal medication (both oral and topical), his skin completely cleared. This case shows why doctors need to consider rare fungal infections when skin problems don’t respond to typical treatments.

Humans vs. Fungi: An Overview of Fungal Pathogens against Humans

mycolabadmin

Fungal infections are serious health threats that kill approximately 1.5 million people annually worldwide. This comprehensive review identifies over 280 different fungal species that can infect humans, with Aspergillus being the most dangerous genus. The study provides updated information on how these infections are diagnosed through various methods including cultures, microscopy, and molecular testing, as well as treatment options ranging from traditional antifungal drugs to newer therapies like nanotechnology-based formulations.

Advances in Fungal Infection Research: From Novel Diagnostics to Innovative Therapeutics

mycolabadmin

Fungal infections are becoming increasingly serious, especially for people with weakened immune systems, and some fungi are developing resistance to current medications. Researchers are developing faster diagnostic tests using molecular techniques and exploring new treatment approaches including repurposing existing drugs and developing vaccines. Monitoring and prevention programs in hospitals are essential to control the spread of these infections and improve patient outcomes.

Deubiquitinase Ubp5 is essential for pulmonary immune evasion and hematogenous dissemination of Cryptococcus neoformans

mycolabadmin

Researchers studied a protein called Ubp5 that helps the fungus Cryptococcus neoformans cause disease in humans. By removing this protein, the fungus became much less harmful and the immune system could fight it better. The fungus with the missing protein had problems with its outer coating, couldn’t hide as well from the immune system, and couldn’t spread to the brain. This suggests that blocking Ubp5 could be a new way to help the body defend against this dangerous fungal infection.

Plants, fungi, and antifungals: A little less talk, a little more action

mycolabadmin

Researchers propose looking at how plants communicate with fungi to discover new antifungal medicines. Plants send chemical signals to fungi, and understanding these signals could help us develop better treatments for fungal infections in humans and crops. By studying a simple yeast model, scientists found that plant molecules called strigolactones control fungal phosphate metabolism, suggesting they could become new drug targets.

Medical Mycology Education in Brazil: A Cross-Sectional Survey of Medical Schools

mycolabadmin

This study examined how medical schools in southern Brazil teach students about fungal infections. The researchers surveyed 19 medical schools and found that while all schools include some mycology teaching, it is not offered as a standalone course and there are significant gaps in practical training, laboratory facilities, and instructor expertise. The study highlights that despite Brazil’s burden of serious fungal infections, future doctors are often not adequately prepared to recognize and manage these diseases.
