![]() However, the effects of chytridiomycosis on amphibian species and even within one species are variable. respiration and the maintainance of the water balance, and is often lethal. This fungal infection disturbs the vital function of the skin, e.g. The chytridiomycete fungus, Batrachochytrium dendrobatidis, found to parasitize on amphibian skin, was identified as prevailing cause of these amphibian declines (see e.g. Especially in biodiversity hotspots like Central America, the Caribbean and Australia, amphibians expirienced “enigmatic” declines. In the late nineties, sudden mass mortalities in amphibian populations from pristine or protected areas were observed. Habitat destruction, alteration and fragmentation, commercial over-exploitation for pet-trade and food, introduction of non-native species, infectious diseases and climate disturbance have been identified as stressors of decline. According the latest assessment of the IUCN Red List of Threatened Species (update 2015) at least 41% of all extant amphibian species is at risk of extinction. Furthermore, we pinpoint areas in which more detailed studies are necessary or which have not received the attention they merit.Īmphibians worldwide are dwindling both in numbers and distribution area. salamandrivorans with the host’s skin are integrated. With this review we aim to provide the reader with a state-of-the art of host-pathogen interactions for both fungi, in which new data pertaining to the interaction of B. Other striking differences between both fungi include gross pathology and thermal preferences. salamandrivorans it is limited to European salamanders. ![]() dendrobatidis is mainly limited to Australian, neotropical, South European and West American amphibians, while for B. salamandrivorans seems limited to urodeles. dendrobatidis infects the skin of a large range of anurans, urodeles and caecilians, whereas to date the host range of B. The clinical outcome of infection is highly dependent on the amphibian host, the fungal virulence and environmental determinants. Not all amphibians respond equally to infection and host responses might range from resistant, over tolerant to susceptible. The skin disease caused by these fungi is named chytridiomycosis and affects the vital function of amphibian skin. Infectious drivers of these declines include the recently emerged fungal pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans (Chytridiomycota).
