No Bd in Lyciasalamandra (but Bd occurs in Turkey)

A new paper by Bayram Göçmen et al. published in the journal Salamandra (link) suggests that there is no Bd in the terrestrial salamanders of the genus Lyciasalamandra. Earlier this year, Chiari et al. reported in a paper published in Amphibia-Reptilia that there was no Bd in terrestrial Hydromantes salamanders and last year Lötters et al. published a paper in Salamandra showing that there was no Bd in the terrestrial Salamandra atra. Is it a general rule that there is no Bd in terrestrial salamanders?
