Phaeoacremonium tuscanicum and Phaeoacremonium indicum sp. nov. associated with subcutaneous phaeohyphomycosis

mycolabadmin

Researchers identified and described two rare fungal infections caused by Phaeoacremonium species in human patients. One case involved a previously unknown fungal species in humans called Phaeoacremonium indicum, discovered in an Indian transplant patient with a knee infection. Both cases were successfully treated with surgery, with one patient also receiving antifungal medication, demonstrating effective treatment approaches for these unusual infections.

Different Infection Structures and Point Mutation of Diaporthe citri Showing Resistant against Systemic Fungicides

mycolabadmin

Citrus melanose, a serious fungal disease affecting citrus crops, is increasingly difficult to control due to the development of fungicide-resistant fungal strains. This study examined how resistant and susceptible Diaporthe citri strains respond to two common fungicides. The researchers found that resistant strains have genetic mutations that allow them to overcome fungicide treatments, particularly a specific change in the β-tubulin gene. Understanding these resistance mechanisms is crucial for developing better strategies to manage citrus diseases.

Four Unrecorded Species of Endophytic Diaporthe (Sordariomycetes) in Korea

mycolabadmin

Researchers in Korea discovered four previously unknown species of Diaporthe fungi living inside plant tissues without causing visible damage. These fungi were identified using genetic analysis and compared to known species from around the world. The findings show that Korea has more fungal diversity than previously documented and suggest these fungi could potentially be used to develop new medicines or help control plant diseases.

Biological characterization and in vitro fungicide screening of a new pathogen of basal stem rot of Schisandra chinensis in Jilin Province, China

mycolabadmin

Researchers discovered that a fungus called Ilyonectria robusta is causing a serious disease in Schisandra chinensis plants grown in northern China. This plant is used to make traditional Chinese medicine. The disease causes the base of the plant stems to rot and die. Scientists tested seven different fungicides (medicines that kill fungi) and found that fluazinam was the most effective at stopping this fungus from growing.

Phaeoacremonium tuscanicum and Phaeoacremonium indicum sp. nov. associated with subcutaneous phaeohyphomycosis

mycolabadmin

Researchers identified two cases of rare fungal skin infections caused by Phaeoacremonium species. One case involved a new fungal species named Phaeoacremonium indicum discovered in an Indian patient, while the second case from Australia represented the first documented human infection with P. tuscanicum. Both patients were successfully treated through surgical removal of the infected tissue, though one patient was immunocompromised from a kidney transplant. This study highlights how genetic testing helps identify rare fungal species that cause human infections.

Phylogenetic and Morphological Analysis of a Novel Allocucurbitaria Species Isolated from Lelia decempunctata in South Korea

mycolabadmin

Scientists in South Korea discovered a new fungal species living on a stink bug. By analyzing its genetic material and physical characteristics, they confirmed it was a previously unknown species and named it Allocucurbitaria koreanum. This is the first time this type of fungus has been found associated with insects, suggesting these fungi may have interesting relationships with insects that researchers need to study further.
