Invasive Candidiasis in Contexts of Armed Conflict, High Violence, and Forced Displacement in Latin America and the Caribbean (2005–2025)

mycolabadmin

Invasive candidiasis, a serious fungal blood infection caused by Candida species, is a major health crisis in Latin America and the Caribbean with death rates reaching 60% in vulnerable populations. The disease is worsening in areas affected by armed conflict, violence, and displacement where poor living conditions, overcrowding, malnutrition, and lack of healthcare create ideal conditions for the infection to develop and spread. Antifungal drugs are often unavailable or too expensive, and drug-resistant strains of Candida are becoming increasingly common, making treatment extremely challenging in these regions.

Ex Vivo Host Transcriptomics During Cryptococcus neoformans, Cryptococcus gattii, and Candida albicans Infection of Peripheral Blood Mononuclear Cells From South African Volunteers

Researchers studied how human immune cells respond to three different fungal infections that commonly affect people with weakened immune systems. By examining gene activity in blood cells exposed to these fungi, they discovered that each fungus triggers different immune responses, with Candida albicans causing a much stronger reaction than the two Cryptococcus species. Only one shared immune pathway was activated by all three fungi, suggesting each infection requires different immune mechanisms to fight off. These findings could help develop new treatments for serious fungal infections.

Abundant Yet Aberrant T Helper Cell Responses to Candida albicans Underlie Mucosal Candidiasis in Humans and Mice

Researchers studied how the immune system fights Candida albicans fungal infections. They found that a specific type of immune cell called Th17 cells is absolutely essential for controlling these infections, while other immune cells called Th2 cells actually make infections worse by blocking the protective Th17 cells. Patients with certain genetic mutations that affect how their immune system works have too many Th2 cells and not enough Th17 cells, making them vulnerable to chronic fungal infections. The study suggests that blocking a molecule called IL-4 could help restore the balance and improve patient outcomes.

Changing Climate, Changing Candida: Environmental and Social Pressures on Invasive Candidiasis and Antifungal Resistance in Latin America

mycolabadmin

Invasive fungal infections caused by Candida species are becoming increasingly common and dangerous in Latin American hospitals, with newer strains showing resistance to multiple antifungal drugs. Rising temperatures from climate change and widespread use of fungicides in agriculture appear to be selecting for these resistant fungi. Most hospitals in the region lack advanced diagnostic tools to quickly identify which fungal strain is causing infection, leading to delayed and sometimes inappropriate treatment. Implementing better diagnostic access, stricter antifungal use policies, and coordinated surveillance programs across the region could help control this growing public health problem.

The Gcn5 lysine acetyltransferase mediates cell wall remodeling, antifungal drug resistance, and virulence of Candida auris

mycolabadmin

Candida auris is a dangerous fungal infection that resists many standard antifungal drugs. Researchers discovered that a protein called Gcn5 helps this fungus survive both drugs and the body’s immune system. By targeting Gcn5 with a new compound called CPTH2, scientists showed they could make the fungus more vulnerable to standard treatments like caspofungin, suggesting a promising new approach to fighting these infections.

Candida krusei Empyema: A Lung Transplant Case and Systematic Review of the Literature

mycolabadmin

Candida krusei is a dangerous yeast that causes a serious lung infection called empyema, where pus collects around the lungs. This infection is particularly difficult to treat because the yeast is resistant to common antifungal drugs like fluconazole and can form protective biofilms. This systematic review identified only ten cases of this rare infection in the medical literature, showing how uncommon but serious it is, and found that patients need aggressive treatment with multiple antifungal medications combined with surgical drainage to survive.

Screening of yeasts in the oral microbiota of bats (Chiroptera) in Piauí, Brazil

Researchers collected oral samples from 47 bats in Brazil and found that over 40% carried yeast species, including some dangerous types like Candida albicans that cause infections in humans. The study identified that bats living near human settlements may serve as reservoirs for these disease-causing fungi, especially during rainy seasons when conditions favor yeast growth. This discovery highlights the importance of monitoring wildlife for infectious diseases to prevent them from spreading to humans.

Antifungal stewardship in the UK: where are we now?

mycolabadmin

This paper examines how well the UK is currently managing antifungal stewardship—the appropriate use of antifungal medications to treat serious fungal infections while preventing resistance. Experts found that since 2017, progress has been limited due to lack of funding and staff expertise, difficulties accessing timely fungal diagnostic tests, and disruptions from the COVID-19 pandemic. The panel recommends creating regional mycology networks and diagnostic centres, establishing national standards for antifungal practices, and improving education about fungal infections to better prepare the UK for rising fungal disease threats.

Renaming Candida glabrata—A case of taxonomic purity over clinical and public health pragmatism

mycolabadmin

Candida glabrata is a common yeast infection that causes serious illnesses in humans, affecting millions of people worldwide. Scientists have recently proposed renaming it to Nakaseomyces glabrata for technical taxonomic reasons. However, this article argues against the change because it would create confusion for doctors, complicate treatment instructions on medications, disrupt disease tracking systems, and make it harder for patients to understand their conditions. Keeping the familiar name Candida glabrata is more practical and helpful for patient care and public health than strict adherence to taxonomic classification rules.

PTP1B deficiency in myeloid cells increases susceptibility to Candida albicans systemic infection by modulating antifungal immunity

mycolabadmin

This research shows that a protein called PTP1B plays an important role in protecting the body against dangerous fungal infections caused by Candida albicans. When mice lacked this protein in their immune cells, they were much more susceptible to the infection and showed severe illness. The study found that PTP1B helps immune cells like macrophages and neutrophils fight the fungus effectively, and blocking this protein could actually make fungal infections worse.
