How European hibernating bats cope with white-nose syndrome which kills millions of North American bats
Fungal diseases are a major threat to wildlife, sometimes resulting in significant population declines or even causing the extirpation of populations or species. ten führten.

White-nose syndrome, caused by the cold-loving fungus Pseudogymnoascus destructans, has become a major cause of death for hibernating bats in North America. European bats survive when infected by the same fungus during hibernation. What are the reasons for such a contrast in outcomes? A scientist team led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) has now analysed the humoral innate immune defence of European greater mouse-eared bats to the fungus. In contrast to North American bats, European bats have sufficient baseline levels of key immune parameters and thus tolerate a certain level of infection throughout hibernation. The results are published in the journal “Developmental and Comparative Immunology”.
