Popis: Batrachochytrium dendrobatidis (Bd) is commonly termed the 'amphibian chytrid fungus' but thus far has been documented to be a pathogen of only batrachian amphibians (anurans and caudatans). It is not proven to infect the limbless generally poorly known and mostly soil dwelling caecilians (Gymnophiona). We conducted the largest qPCR survey of Bd in caecilians to date for more than 200 field swabbed specimens from five countries in Africa and South America representing nearly 20 species 12 genera and 8 families. Positive results were recovered for 58 specimens from Tanzania and Cameroon (4 families 6 genera 6+ species). Quantities of Bd were not exceptionally high with genomic equivalent (GE) values of 0.052 17.339. In addition we report the first evidence of lethal chytridiomycosis in caecilians. Mortality in captive (wild caught commercial pet trade) Geotrypetes seraphini was associated with GE scores similar to those we detected for field swabbed wild animals. © 2013 International Association for Ecology and Health.
