Abstract	Many amphibians are known to suffer embryonic die-offs as a consequence of Saprolegnia infections; however, little is known about the action mechanisms of Saprolegnia and the host–pathogen relationships. In this study, we have isolated and characterized the species of Saprolegnia responsible for infections of embryos of natterjack toad (Bufo calamita) and Western spadefoot toad (Pelobates cultripes) in mountainous areas of Central Spain. We also assessed the influence of the developmental stage within the embryonic period on the susceptibility to the Saprolegnia species identified. Only one strain of Saprolegnia was isolated from B. calamita and identified as S. diclina. For P. cultripes, both S. diclina and S. ferax were identified. Healthy embryos of both amphibian species suffered increased mortality rates when exposed to the Saprolegnia strains isolated from individuals of the same population. Embryonic developmental stage was crucial in determining the sensitivity of embryos to Saprolegnia infection. The mortalities of P. cultripes and B. calamita embryos exposed at Gosner stages 15 (rotation) and 19 (heart beating) were almost total 72 h after challenge with Saprolegnia, while those exposed at stage 12 (late gastrula) showed no significant effects at that time. This is the first study to demonstrate the role of embryonic development on the sensitivity of amphibians to Saprolegnia.
