Improved method for genotyping the causative agent of crayfish plague (Aphanomyces astaci) based on mitochondrial DNA

Parasitology, 2019
Aphanomyces astaci causes crayfish plague, which is a devastating disease of European freshwater crayfish. The likely first introduction of A. astaci into Europe was in the mid-19th century in Italy, presumably with the introduction of North American ...

On the Adaptation of Aphanomyces astaci as a Parasite

Physiologia Plantarum, 1969
AbstractThe crayfish plague parasite Aphanomyces astaci was compared with some other species of Aphanomyces in several physiological respects to detect signs of specialization in the plague fungus which could be connected with its life as a parasite.Thus, A. astaci showed good growth in crayfish serum in contrast to the other species.

Studies on the Crayfish Plague Fungus Aphanomyces astaci

Physiologia Plantarum, 1966
AbstractA mycelial suspension of the crayfish plague fungus, Aphanomyces astaci, was able to produce large numbers of zoospores, when transferred to redistilled water, at 20°C, even after storage for months at 2°C. Spore production was greater in redistilled water than in tap water and heavier under shake conditions than under stationary ones.

Laboratory investigations of the pathogenicity of Aphanomyces astaci for Irish freshwater crayfish

Hydrobiologia, 1990
Crayfish plague, caused by the oomycete Aphanomyces astaci, was first diagnosed in Irish stocks of Austropotamobius pallipes from a midlands limestone lake and crayfish farm in October, 1987. Behavioural activity of infected crayfish was monitored and the position at death noted.

Blood reactions in vitro in crayfish against a fungal parasite, Aphanomyces astaci

Journal of Invertebrate Pathology, 1972
Abstract The immediate and subsequent reactions in crayfish blood upon making contact with hyphae of the crayfish plague fungus were observed in vitro. Blood cells agglomerated and clumped rapidly on the hyphae in streaming blood. Very brief contact by chance with a hypha, or with cell extensions from cells or a cell clump on the hypha, caused ...
