“…The current scattered distribution of Bsal in Europe (Dalbeck et al, 2018; Spitzen‐van der Sluijs et al, 2016), the poor detectability of sick and deceased individuals (unpubl. data) and the variable prevalence in wild salamander and newt populations (Dalbeck et al, 2018; Spitzen‐van der Sluijs et al, 2016; 2018; Yuan et al, 2018), is factors that make active surveillance for Bsal cost‐ineffective, while Bsal has the potential to further expand (Beukema et al, 2018) either via anthropogenic or natural pathways (e.g., Fitzpatrick, Pasmans, Martel, & Cunningham, 2018; Stegen et al, 2017). Active surveillance for Bsal is performed by collecting skin swabs from the amphibian host (Hyatt et al, 2007), and then analyzing these swabs for the presence of Bsal DNA using quantitative PCR (qPCR) techniques (Blooi et al, 2015a; 2015b).…”
