Coexistence of Malassezia Species and Microsporum canis in the Lesions of Adult with Tinea Capitis

mycolabadmin

A 60-year-old woman developed unusual hair loss and scalp inflammation that looked like dandruff but was actually a fungal infection caused by multiple fungi working together. Doctors found three different fungi in her scalp samples: one dermatophyte and two Malassezia species. Lab experiments showed that the Malassezia fungi actually helped the main disease-causing fungus grow better, which explains why the condition looked different from typical cases. After three months of antifungal medication, her symptoms cleared and her hair grew back.

Phylogenetic placements and cultural characteristics of Tuber species isolated from ectomycorrhizas

Researchers successfully grew truffle fungi in the laboratory by isolating them from the roots of fir trees in Japanese forests. They identified eight different truffle species or lineages and studied how they grew on nutrient agar plates, finding that while they shared basic characteristics like white filamentous colonies, they had many differences in growth rates and hyphal structure. The study shows that collecting truffles from tree roots can be an effective way to obtain pure cultures of these fungi when fruiting bodies cannot be found.

Essential Oils as an Antifungal Alternative to Control Several Species of Fungi Isolated from Musa paradisiaca: Part II

Bananas often develop fungal infections during storage that reduce their quality. Researchers tested whether essential oils from common herbs and spices like cinnamon, clove, and oregano could prevent these fungal infections. The study found that cinnamon, clove, and oregano oils effectively stopped fungal growth at higher concentrations, offering a natural alternative to chemical fungicides that could help keep bananas fresh longer without synthetic chemicals.

Shifting etiological agents of dermatophytosis: a molecular epidemiological study from Iran

mycolabadmin

Researchers in Iran studied fungal infections of the scalp and nails using modern DNA testing methods. They found that the main fungus causing scalp infections (T. tonsurans) remains the most common, but a new species (T. indotineae) is increasingly causing nail infections and is resistant to common antifungal medicines. The study shows that traditional identification methods often misidentify these fungi, highlighting the importance of molecular testing for accurate diagnosis and treatment.

Ventilator-associated pneumonia caused by a new-found opportunistic fungal pathogen—Myceliophthora heterothallica: a case report

mycolabadmin

A 67-year-old woman suffered cardiac arrest and required a breathing machine to survive. While on the ventilator, doctors discovered an unusual fungal infection in her lungs caused by Myceliophthora heterothallica, which had never been documented as a human pathogen before. With standard bacterial antibiotics and supportive care, the patient recovered and was discharged after four weeks, suggesting this fungus may be less dangerous than related species.

Candida vulturna, the Next Fungal Menace? A Narrative Review

mycolabadmin

Candida vulturna is a newly identified fungus that causes serious bloodstream infections, particularly in newborns and hospitalized patients in tropical regions. Unlike many common fungal infections, it resists several antifungal medications, though it remains susceptible to certain antibiotics called echinocandins. Scientists have documented 94 cases worldwide, including three hospital outbreaks, and the infection has a relatively low death rate of 18%. Accurate identification requires genetic testing since standard hospital laboratory tests often misidentify this pathogen.

Unraveling the Fungi–Cancer Connection

mycolabadmin

Fungi living in and around tumors play surprisingly important roles in cancer development and treatment response, yet they have been largely overlooked compared to bacteria. Different cancer types host specific fungal species that can promote tumor growth through immune suppression and toxin production. By better understanding and potentially targeting these tumor-associated fungi, researchers believe we could develop new combination treatments that enhance the effectiveness of existing cancer therapies.

The first report of rhinosinusitis by Rhizopus delemar in a patient with severe COVID-19 in Iran: a case report

mycolabadmin

A 63-year-old man hospitalized with COVID-19 developed a serious fungal sinus infection caused by a rare mold called Rhizopus delemar. Despite surgery to remove infected tissue and treatment with antifungal medication amphotericin B, the infection spread and the patient died after five weeks. This was the first documented case of this particular mold causing sinus infection in a COVID-19 patient in Iran, highlighting how severe fungal infections can occur as dangerous complications of COVID-19.

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 rare fungal bloodstream infection caused by Magnusiomyces capitatus during cancer treatment. The infection was identified through advanced laboratory techniques including DNA sequencing and mass spectrometry. The patient was successfully treated with amphotericin B, highlighting the importance of rapid and accurate fungal identification for better patient outcomes.

Disseminated Lichtheimia ramosa infection in a Japanese Black calf

mycolabadmin

A young beef calf developed severe diarrhea and fever that did not respond to multiple antibiotics. The calf had an underdeveloped immune system (missing thymus gland) and was treated with many antibiotics and steroids, which weakened its immune system further. After death, examination revealed the calf had a widespread fungal infection caused by Lichtheimia ramosa in the liver and digestive tract, representing the first documented case of this type in Japanese Black cattle.
