Presence of the Fungus B. dendrobatidis, but not B. salamandrivorans, in Wild Pyrenean Brook Newts (Calotriton asper) in Spain and France

摘要: In the last 20 years, emergence of chytridiomycosis due to chytrid fungi Batrachochytrium dendrobatidis (Bd), and more recently described salamandrivorans (Bsal), has caused severe amphibian population regressions across planet (Bosch et al. 2001; Spitzen-van der Sluijs 2016; Scheele 2019). This generated an increase in scientific interest decipher complex interaction between environment, fungus hosts, increased surveillance efforts many localities (Canessa 2020). spp. affect vital function skin, leading lethargy or skin discoloration, hyperkeratosis, erosions (even ulcerations Bsal) epidermis, eventually death (Berger 1998; Weldon 2004; Stuart Wake Vredenburg 2010; Martel 2013). Bd is currently found on all continents where amphibians are present (Skerratt 2007), affecting than 700 species within three orders been considered a major threat biodiversity worldwide (Crawford Fisher 2012; Olson 2013; Ronnenberg 2014).
