Data were generated from a mesocosm experiment to determine the extent to which non-reservoir hosts impact the maintenance and transmission of infections from parasites supported by reservoir hosts. The three host species were salamanders, Tree frogs (Hyla meridiensis) and Spiny toads (Bufo spinosus). The infection used was Batrachochytrium dendrobatidis (Bd). The experiment was executed in the late summer of 2017, at the Centre for Captive Breeding of Threatened Amphibians, located in Rascafria, Spain.

The dataset contains values on the prevalence and mean intensity of Batrachochytrium dendrobatidis (Bd) infection and ranavirus (Rv) infections in different combinations of common frog (Rana temporaria) and common toad (Bufo bufo) during mesocosm experiments executed in the summer of 2018, at the Institute of Zoology, Zoological Society of London (ZSL).
