Chytridiomycose
The chytridiomycose is a fatal Infectious illness affecting the Amphibiens, caused by the chytridiomycète - Batrachochytrium dendrobatidis . The chytridiomycose was related to the spectacular declines, and even extinctions, of populations in North America, Central America, South America, and the east of Australia. There is no effective measure to control the disease among the wild populations. The disease contributes to decline of the populations of Amphibians in the whole world, and has apparently affected 30% of the world species of Amphibians.
Although certain falls of population were allotted to the mushroom B. dendrobatidis , there exist certain species resistant to the infection and certain studies showed that some populations can survive with a low level of persistence of the disease. Moreover, the majority of the studies in laboratory are not ecologically reliable, which returns the application of their conclusions on the ground delicate.
The first reported cases of infection of Batrachochytrium come from the smooth Xénope Xenopus laevis . As this species was very largely widespread throughout the world, it constitutes a potential vector of the transmission of the B. dendrobatidis .
Studies in laboratory suggest that the mushroom tolerates the high temperatures badly, and that to expose the Amphibians infected to high temperatures can eliminate mushroom. This can explain why the chytridiomycose develops mainly under the fresh climates.
