Aphanomyces astaci isolate from latently infected stone crayfish (Austropotamobius torrentium) population is virulent

Journal of Invertebrate Pathology, 2017
Aphanomyces astaci infection is the cause of crayfish plague in European crayfish. Here the virulence of an A. astaci As strain isolated from apparently healthy stone crayfish (Austropotamobius torrentium) from Slovenia was compared to that of the Psl-Puujärvi A.
