Crayfish plague pathogen detected in the Danube Delta - a potential threat to freshwater biodiversity in southeastern Europe

Original language description

The crayfish plague, caused by the oomycete Aphanomyces astaci, is probably the most significant reason for declines in European freshwater crayfish species. One of its hosts, the North American spiny-cheek crayfish Orconectes limosus, extends its rangein the river Danube and recently reached the territory of Romania. We used highly sensitive A. astaci-specific real-time PCR to test if the native narrow-clawed crayfish Astacus leptodactylus in the highly protected Danube Delta about 970 km downstream of the current invasion front of American crayfish is a carrier of the crayfish plague. Thirteen out of 40 analysed native A. leptodactylus tested positive for the crayfish plague pathogen, infected individuals were found at both sampled localities withinthe Danube Delta. Therefore A. astaci has a much wider range in this river than assumed. The pathogen seems to persist in local populations, as neither crayfish mass mortalities nor alien crayfish species have been reported from the regi
