摘要：

Saprolegnia parasitica isolated from freshwater crayfish Astacus leptodactylus was investigated for its ability to infect and kill three different species of crayfish, Astacus astacus, Pacifastacus leniusculus and Procambarus clarkii. Healthy (non-injured) crayfish challenged with zoospores of S. parasitica became infected and ca. 20% died as a result of such infection. If the epicuticle of the crayfish was abrased gently before challenge with zoo-spores, mortality increased significantly, ca. 3 times. There were no significant differences in susceptibility between the three species of crayfish tested against S. parasitica.
