Healthcare-associated fungal infections and emerging pathogens during the COVID-19 pandemic

mycolabadmin

During the COVID-19 pandemic, fungal infections became a serious complication in hospitalized patients, especially those receiving steroids and other immune-suppressing treatments. Common fungal pathogens like Candida and Aspergillus caused dangerous coinfections, with infection rates varying significantly by region. Current antifungal medications have significant limitations including toxicity and resistance, highlighting the urgent need for new and safer antifungal treatments.

A case of rare fungal keratitis caused by Pseudoshiraia conidialis

mycolabadmin

A 61-year-old woman scratched her eye with a bamboo branch and developed a serious fungal eye infection caused by a rare fungus called Pseudoshiraia conidialis. This is the first reported case of this particular fungus infecting human eyes. Although initial treatment with antifungal medications showed promise, the infection proved difficult to cure due to the fungus being resistant to multiple antifungal drugs. The case highlights the importance of early diagnosis and treatment of fungal eye infections.

Informing the World Health Organization Fungal Priority Pathogens List (WHO-FPPL): A collection of systematic reviews

mycolabadmin

The World Health Organization created a priority list of dangerous fungal infections affecting millions of people globally each year. Experts reviewed 19 different fungal pathogens and ranked them by how dangerous they are and how much they need research and treatment development. The list identifies which fungal infections should get the most attention from doctors, researchers, and public health officials to improve patient outcomes and reduce deaths.

Monoclonal Antibodies Can Aid in the Culture-Based Detection and Differentiation of Mucorales Fungi—The Flesh-Eating Pathogens Apophysomyces and Saksenaea as an Exemplar

mycolabadmin

This research developed a special antibody test to quickly identify deadly flesh-eating fungi called Apophysomyces and Saksenaea, which cause serious skin and soft tissue infections. These fungi are difficult to identify because they don’t form spores on standard laboratory media. The new test uses a simple method combining antibody detection with a rapid lateral-flow test, similar to a COVID-19 test, making diagnosis faster and more reliable in hospitals that don’t have access to expensive equipment.

Synthesis, Physicochemical Properties and Anti-Fungal Activities of New Meso-Arylporphyrins

mycolabadmin

Researchers created three new porphyrin compounds that effectively kill fungal infections like Candida and athlete’s foot fungi. These compounds can also generate singlet oxygen when exposed to light, making them potentially useful for photodynamic therapy treatments. Testing showed they inhibited fungal growth at relatively low concentrations, suggesting they could become new antifungal medications.

Pathogenic mucorales: Deciphering their cell wall polysaccharidome and immunostimulatory potential

mycolabadmin

Researchers studied three dangerous fungi that cause serious infections called mucormycosis. They examined the outer coating of these fungi, called the cell wall, which is made of sugar-like molecules called polysaccharides. When these fungi were exposed to human immune cells, they triggered strong inflammatory responses. Understanding these fungal components could help develop better treatments and vaccines for this life-threatening infection.

Neonatal Invasive Candidiasis: Current Concepts

mycolabadmin

Neonatal invasive candidiasis is a serious fungal infection affecting premature and very low birth weight babies. The types of fungi causing these infections are changing globally, with more resistant strains appearing, especially in lower-income countries. Treatment options are limited by this resistance, making prevention through hygiene and proper hospital practices increasingly important.

Leveraging synthetic genetic array screening to identify therapeutic targets and inhibitors for combatting azole resistance in Candida glabrata

mycolabadmin

Candida glabrata is a dangerous fungus causing serious infections that is becoming resistant to antifungal drugs. Researchers used a genetic screening technique to find genes that interact with drug resistance mutations and identified methotrexate (a drug already used for arthritis) as a potential partner for fluconazole treatment. When combined, these drugs work better together against resistant strains of the fungus, offering hope for treating these stubborn infections.

Insights into Persian Gulf Beach Sand Mycobiomes: Promises and Challenges in Fungal Diversity

mycolabadmin

Researchers studied fungi in beach sand and water along the Persian Gulf and Sea of Oman coasts during summer months. They found high levels of potentially harmful fungi, especially Aspergillus terreus, which can cause serious respiratory infections. Many of these fungi showed resistance to common antifungal medications. The study recommends better hygiene awareness for beach visitors and establishing safety standards for these popular recreational areas.

Do farnesol and tyrosol production in Candidozyma auris biofilms reflect virulence potential?

mycolabadmin

Researchers discovered that a dangerous fungus called Candidozyma auris produces signaling molecules called farnesol and tyrosol in biofilms. These molecules appear to be linked to how dangerous the fungus is—strains that produce more of these molecules were more virulent in infection studies. Understanding these signaling molecules could help develop new strategies to fight this drug-resistant pathogen.
