Declining of amphibian populations is a worldwide phenomenon. A cutaneous m
ycosis 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, N
orth, Central and South America. This is the first report on chytrid infect
ions in captive anurans from Europe. Dendrobates auratus and D. pumilo impo
rted from Costa Rica and P. vittatus imported from French Guayana died with
chytridiomycosis within a week after arrival in Europe. Batrachocytrium wa
s 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.
