Screening microbial inhibitors of Pseudogymnoascus destructans in Northern China

mycolabadmin

Scientists in Northern China have found bacteria living on bat skin and in cave soil that can kill the fungus responsible for white-nose syndrome, a disease devastating bat populations worldwide. These bacteria produce various antifungal compounds including volatile organic compounds that diffuse through the air and damage the fungus’s structure. By analyzing the genetic makeup of these bacteria, researchers identified specific genes responsible for producing these antifungal compounds, offering hope for developing biological control treatments that could protect bats and reduce fungal loads in cave environments.

Insight into the Skin Mycobiota of Myotis myotis: How Age, Sex, and Biometric Traits Correlate with Fungal Diversity

mycolabadmin

Researchers studied fungal colonies living on the skin of Greater mouse-eared bats in autumn, discovering 39 different fungal species. Wing membranes had more fungal diversity than tail membranes, with males carrying more fungi than females. Interestingly, older male bats accumulated more fungal species, while older female bats showed less fungal diversity. The study found no trace of the fungus that causes white-nose syndrome, suggesting caves rather than bats may be the main source of this disease.

Mapping Histoplasma spp. in bats and cave ecosystems: evidence from midwestern Brazil

mycolabadmin

Researchers found that caves in Brazil harbor a dangerous fungus called Histoplasma that can cause a serious lung disease in humans. The study detected the fungus in soil samples from several caves and in multiple bat species living in those caves. The findings show which caves are most dangerous and emphasize the need for warning signs and protective measures for cave visitors and workers in the region.
