Dermatophytosis in a Chilean fox: first case of Nannizzia gypsea in Lycalopex griseus and the need for a one health approach

mycolabadmin

A young wild Chilean fox was found with a skin infection caused by a fungus called Nannizzia gypsea, which lives in soil and can infect animals and humans. This is the first time this fungus has been documented in foxes anywhere. Doctors treated the fox with an antifungal cream and it recovered completely. The case highlights how increasing urbanization and contact between domestic pets, wild animals, and humans can spread fungal diseases, emphasizing the need for a coordinated public health approach.

Pathogenic potential of polyextremotolerant fungi in a warming world

mycolabadmin

Certain fungi can survive extremely harsh conditions like extreme temperatures and dry environments, and many of these same species can cause infections in humans. As the planet warms due to climate change, these fungi are becoming better adapted to higher temperatures, which makes them more dangerous as human pathogens. Scientists are working to better understand these fungi and develop new treatments and vaccines to protect people from fungal infections.

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.

Fatal Pneumonia Caused by Beauveria bassiana in a Kemp’s Ridley Sea Turtle (Lepidochelys kempii, Garman, 1880) on the Portuguese Coast: Case Report and Review of Beauveria spp. Infections in Reptiles

mycolabadmin

A young Kemp’s ridley sea turtle, one of the world’s most endangered turtle species, was found off the coast of Portugal and brought to a rehabilitation center. Despite intensive care, the turtle died after 11 days due to a severe fungal lung infection caused by Beauveria bassiana, a fungus that normally infects insects. This case highlights how endangered animals in poor health are vulnerable to opportunistic infections and emphasizes the importance of including fungal disease screening in wildlife rehabilitation programs.

Superficial abdominal surgical site infection caused by Aspergillus welwitschiae: a case report

mycolabadmin

An elderly woman developed a rare fungal infection in her abdominal surgical wound after surgery for a perforated colon. The infection was caused by Aspergillus welwitschiae, a mold that was initially thought to be a more common species. Doctors treated the infection by surgically removing the infected tissue and giving the patient an antifungal medication called voriconazole. This is the first reported case of this particular mold causing this type of surgical infection.

Dermatophytosis in a Chilean fox: first case of Nannizzia gypsea in Lycalopex griseus and the need for a one health approach

mycolabadmin

Researchers reported the first case of a fungal skin infection caused by Nannizzia gypsea in a wild South American grey fox found near Santiago, Chile. The fox developed crusted and scaly lesions on its tail, which were successfully treated with topical antifungal cream. This discovery highlights how increasing contact between domestic pets, wild animals, and humans due to urbanization can spread fungal infections, emphasizing the need for integrated health approaches that consider human, animal, and environmental health together.

Taxonomic revision of Bisifusarium (Nectriaceae)

mycolabadmin

Scientists have identified and formally named 8 new species of Bisifusarium, a genus of fungi found in cheese, soil, and some human infections. Using genetic analysis and careful observation of fungal structures, researchers studied 116 fungal samples collected from around the world. This work more than doubled the known number of Bisifusarium species from 16 to over 24, providing clearer identification methods for future research in food science and medicine.

Dermatophytes adaptation to the human host exemplified by Microsporum canis

mycolabadmin

Researchers studied how fungi that normally infect cats and dogs are adapting to infect humans. By comparing the genes of zoophilic (animal-loving) and anthropophilic (human-loving) Microsporum species, they found that human-adapted strains have developed specific proteins that help them survive in the acidic environment of human skin. These fungi have evolved special enzymes for breaking down keratin and tolerating the lipid-rich, acidic conditions of human skin better than their animal-loving relatives.

Insecticidal Action of Local Isolates of Entomopathogenic Fungi Against Bactrocera oleae Pupae

mycolabadmin

Olive farmers in Mediterranean countries struggle with the olive fruit fly, which damages olives and reduces oil production. Researchers tested special fungi that naturally infect and kill insects to see if they could control this pest at the soil stage when fly pupae are developing underground. Several fungal species, especially Beauveria bassiana, were effective at reducing survival of emerged adult flies by about 40% compared to untreated flies. This offers a promising natural alternative to chemical pesticides that can harm olive oil quality and lose effectiveness over time.

Breaking down the wall: Solid-state NMR illuminates how fungi build and remodel diverse cell walls

mycolabadmin

Scientists have developed a new technique called solid-state NMR that can examine fungal cell walls without damaging them, revealing how these structures are built and reorganized. This research shows that different fungi have different wall architectures made of sugar-like molecules including chitin and various glucans, and that fungi can quickly adapt their walls when exposed to antifungal drugs. These findings could help develop better antifungal treatments by targeting the specific structural features that different fungi rely on for survival.
