Well Chytrid has been found in captive collections when testing has been used as well as in at least one importer...

See http://www.ncbi.nlm.nih.gov/sites/entrez?cmd=Retrieve&db=PubMed&list_uids=11084755&dopt=AbstractPlus

http://www.jwildlifedis.org/cgi/content/abstract/37/1/1 for some of the discussion.

Often we do not see the mortality in captive animals because the amphibians are usually not necropsied and may usually be kept at temperatures above 75 F (which is above the temperature at which chytrid becomes lethal...) however there is disturbing information coming out of the Zoo community where groups of anurans that have tested negative are suddenly coming up positive with a loss of animals. There is now speculation that there is a resistant spore (which some other chytrids have) that is allowing these infections ot occur. The suspected source of the infection is a resistant spore that comes in with some outside source like cage furnishings or even the water... (but I want to stress that this is still speculation).

I am interested in seeing the actual article post publication to see what was actually done with the treatments as there maybe cofounding issues (such as keeping the frogs say at 82 F which is above the lethal zone for chytrid). The media article is troubling as it lists the frogs as becoming resistant and cured and these two things are not necessarily the same thing....
