The Spatial Distribution of Aphanomyces astaci Genotypes Across Europe: Introducing the First Data from Ukraine
Original language description
Aphanomyces astaci is the causative agent of crayfish plague, a disease responsible for numerous mass mortalities of native crayfish across Europe. In this study, we aim to extend knowledge about the A. astaci distribution in Eastern Europe, with specific focus on the River Dnieper (Ukraine), and summarize presently available information about the distribution of genotypes of this pathogen across the Western Palaearctic. We compiled published records about genotype groups of A. astaci, assembled them to a comprehensive map, and added the newly obtained results from Ukraine. The native narrow-clawed crayfish Pontastacus leptodactylus was sampled from the river Dnieper in Svydivok and Kiev, ca 170 km apart, and screened for the pathogen presence in soft cuticles by quantitative PCR. We confirmed infections by A. astaci at both sites, with prevalence exceeding 30% and low to medium agent levels in infected crayfish. Pathogen genotyping confirmed the presence of the A. astaci haplogroup B, associated with the signal crayfish Pacifastacus leniusculus but also known from some chronically infected narrowclawed crayfish from Turkey and Moldova. Our results support the notion that latent A. astaci infections among narrow-clawed crayfish populations may be widespread in Eastern Europe and the Middle East. Copyright (C) 2020 by The Author(s).
