Chytridiomycosis on amphibians - first report from Europe.

: Declining of amphibian populations is a worldwide phenomenon. A cutaneous mycosis as a cause of death in free-living amphibians as well as in captive ones due to an chytrid fungus (Batrachochytrium dendrobatidis) was reported at first in 1998. This infections were reported hitherto from Australia, North, Central and South America. This is the first report on chytrid infections in captive anurans from Europe. Dendrobates auratus and D. pumilo imported from Costa Rica and P. vittatus imported from French Guayana died with chytridiomycosis within a week after arrival in Europe. Batrachocytrium was also found on captive bred frogs in Germany and Belgium. Clinical signs, diagnosis and conclusions for protecting free-living amphibian populations and captive frogs are discussed.
