Candida blankii: The Difficult Capture of a Fungus With Pathogenic Potential

mycolabadmin

Candida blankii is a rare fungal pathogen that is increasingly being found in hospital patients’ bloodstreams and respiratory tracts. The organism is difficult to identify using standard laboratory tests, which can delay diagnosis and treatment. This case report describes two adult patients with C. blankii infections and highlights the challenges in identifying this emerging pathogen and its resistance to common antifungal medications.

The association of Yarrowia lipolytica with onychomycosis

mycolabadmin

A 20-year-old woman had a persistent toenail infection that did not respond to multiple antifungal treatments. Researchers identified the cause as Yarrowia lipolytica, an unusual yeast that had never been found causing nail infections before. The yeast was resistant to several common antifungal medications, explaining why previous treatments failed. This case shows the importance of identifying the exact fungus causing an infection to develop effective treatment strategies.

Phaeoacremonium iranianum – a new corneal pathogen

mycolabadmin

A 66-year-old man developed a serious eye infection from a fungus called Phaeoacremonium iranianum after his eye was scratched by a leaf. This is the first reported case of this fungus causing a corneal infection. Doctors treated the infection with antifungal eye drops and surgery to remove infected tissue, and the patient’s condition improved over time, though with some permanent scarring of the cornea.

Simplicillium sinense sp. nov., a novel potential pathogen of tinea faciei

mycolabadmin

Researchers identified a new fungal species called Simplicillium sinense that caused a facial skin infection (tinea faciei) in a 46-year-old man with diabetes. The fungus was resistant to most common antifungal medications but responded well to terbinafine treatment. This is the first reported case of a Simplicillium infection causing facial ringworm, expanding our understanding of rare fungal pathogens.

Invasive Saprochaete capitata Infection in an Immunocompromised Patient With Acute Myeloid Leukemia: A Case Report

mycolabadmin

A 46-year-old man with blood cancer developed a serious fungal infection caused by Saprochaete capitata during chemotherapy. This rare but dangerous fungus was found in his blood and lungs, causing fever and breathing problems. The patient was successfully treated with a combination of two antifungal medications and fully recovered, though this infection typically has a high death rate.

Pathogenic characterization of Phialophora submersa, a new black yeast isolated from freshwater sediments in Spain

mycolabadmin

Scientists discovered a new black yeast fungus called Phialophora submersa in Spanish river sediments and tested whether it could infect humans. Using laboratory macrophage (immune cell) models, they found that this environmental fungus exhibits pathogenic potential similar to known disease-causing Phialophora species, though at intermediate levels. The fungus showed resistance to some antifungal drugs and displayed strain-dependent ability to survive various stress conditions. This research suggests that environmental fungal species may pose unexpected health risks despite not being able to grow at normal human body temperature.
