Successful Treatment of Fungal Dermatitis in a Bottlenose Dolphin (Tursiops truncatus)

mycolabadmin

A bottlenose dolphin at a Japanese aquarium developed a serious fungal infection on its tail fin while suffering from severe digestive problems and weight loss. The infection was caused by two types of fungi that are normally hard to treat because they resist many antifungal medications. Veterinarians successfully treated the dolphin using a combination of two antifungal drugs (voriconazole and terbinafine), surgical removal of dead tissue, and daily wound cleaning with special solutions. The dolphin’s wound eventually healed completely, and this is the first documented successful treatment of these particular fungal infections in bottlenose dolphins.

Airborne Fungal Spore Diversity Assessment Using Culture-Dependent and Metabarcoding Approaches in Bat-Inhabited Natural and Anthropogenic Roosts in Portugal

mycolabadmin

Researchers studied fungal diversity in bat caves across Portugal using two methods: growing fungi in labs and analyzing DNA from air samples. They found over 280 different types of fungi, with some being common decomposers and others potentially harmful to human health. The study revealed that bat activity and human visits significantly influence which fungi live in caves, highlighting the importance of protecting these unique underground ecosystems.

First Report of Diaporthe goulteri on Soybean in Germany

mycolabadmin

Researchers in Germany discovered a fungal disease called Diaporthe goulteri infecting soybean plants for the first time. This fungus, previously known only from sunflowers in Australia, was isolated from a soybean seed and confirmed through genetic testing. Laboratory experiments showed the fungus can infect soybean stems and cause dark discoloration and tissue damage. This finding is important for soybean farmers as it indicates a new disease threat that may need to be monitored and managed.

Bioprospecting of four Beauveria bassiana strains and their potential as biological control agents for Anastrepha ludens Loew 1873 (Diptera: Tephritidae)

mycolabadmin

Researchers tested four strains of a beneficial fungus called Beauveria bassiana from Mexico to see if they could control the Mexican fruit fly, a major pest that damages mango and orange crops. The fungus naturally infects insects and kills them. Tests showed that all four strains were very effective at killing adult fruit flies, with the best performance at higher spore concentrations. These locally adapted fungal strains may work better than imported alternatives for farmers in the Veracruz region.

Magnusiomyces capitatus bloodstream infection in a patient with acute monocytic leukemia: A rare case report

mycolabadmin

A 26-year-old patient with acute leukemia developed a serious fungal blood infection caused by Magnusiomyces capitatus, a rare organism found in environmental sources. The infection was confirmed using advanced molecular techniques and showed resistance to common antifungal drugs but responded to amphotericin B treatment. This case highlights how important it is for doctors to consider unusual fungi in severely immunocompromised patients and to use modern diagnostic methods for accurate identification and tailored treatment.

Insights into Physicochemical Characteristics, Flavor Development, and Microbial Succession During the Natural Fermentation of Sichuan-Style Black Soybean Soy Sauce

mycolabadmin

This research reveals how Sichuan-style black soybean soy sauce develops its distinctive complex flavor over six months of natural fermentation. The study tracked changes in taste and aroma compounds, identifying key flavor contributors like methional (sauce-like) and 1-octen-3-ol (mushroom-like). Different microorganisms dominate at different fermentation stages, with early-stage fungi breaking down proteins and later-stage bacteria and yeasts creating aromatic compounds. The findings provide insights for improving traditional soy sauce production methods.

Deep cutaneous fungal infection in an immunocompetent individual caused by a biological pesticide: a rare case report

mycolabadmin

A 66-year-old farmer developed a deep skin fungal infection from a biological pesticide she used for over 10 years. The pesticide contained a fungus called Purpureocillium lilacinum, which is normally harmless to healthy people but caused repeated skin lesions on her face and arms. She was successfully treated with antifungal medication (itraconazole) for three months, and her skin fully healed without returning. This is the first reported case showing that biological pesticides can pose health risks to workers who handle them regularly.

Disseminated Lichtheimia ramosa infection in a Japanese Black calf

mycolabadmin

A young cow developed a severe fungal infection caused by Lichtheimia ramosa, a rare type of mold. The infection spread throughout the cow’s body, affecting the liver and digestive system. The cow had an underdeveloped immune system (thymus hypoplasia) and was given multiple antibiotics for weeks, which actually made the fungal infection worse by killing normal protective bacteria. Despite various treatments, the cow’s condition worsened and it had to be euthanized.

Feline Cryptococcosis due to Cryptococcus gattii VGII (Recently Renamed as C. deuterogattii) in an FIV-Positive Cat With Demodicosis From Manaus, Central Amazon, Brazil

mycolabadmin

A 20-month-old cat from Brazil’s Amazon region presented with nasal discharge, skin lesions, and a neck mass and was diagnosed with cryptococcosis caused by a dangerous fungus called C. deuterogattii. The cat was also infected with feline immunodeficiency virus (FIV), which weakened its immune system and made it vulnerable to the fungal infection. Treatment with the antifungal medication fluconazole successfully cured the infection within 8 weeks, and the cat made a full recovery.

Detection of Pestalotiopsis abbreviata sp. nov., the Causal Agent of Pestalotiopsis Leaf Blight on Camellia japonica Based on Metagenomic Analysis

mycolabadmin

Researchers discovered a new fungal species called Pestalotiopsis abbreviata that causes leaf disease on Camellia japonica, an ornamental tree popular in Korea. Instead of using traditional time-consuming laboratory methods, they used advanced genetic sequencing (metagenomic analysis) to quickly identify the fungus among hundreds of other microbes living on the tree leaves. This new approach is faster and more accurate than old methods, making it easier to monitor and manage plant diseases in the future.
