The Crayfish Plague Pathogen Aphanomyces astaci in Ireland [PDF]
MicroorganismsCrayfish plague is a devastating disease of European freshwater crayfish and is caused by the oomycete Aphanomyces astaci (Ap. astaci), believed to have been introduced to Europe around 1860. All European species of freshwater crayfish are susceptible to

Prevalence and diversity of Aphanomyces astaci in cambarid crayfish of Pennsylvania: where native and introduced hosts meet [PDF]
ParasitologyThe crayfish plague pathogen Aphanomyces astaci (Oomycota: Saprolegniales) is native to North America but expanded with its crayfish hosts to other regions. In most of its invaded range, A. astaci haplotypes are associated with specific American crayfish,

Mitochondrial genomes and comparative genomics of Aphanomyces astaci and Aphanomyces invadans. [PDF]
Sci Rep, 2016 AbstractThe genus Aphanomyces (Saprolegniales, Oomycetes) includes species with a variety of ecologies from saprotrophs to plant and animal parasites. Two important species in this genus are A. astaci, the cause of crayfish plague and its close relative, A. invadans, which causes the epizootic ulcerative syndrome on fish.

LACK OF SPECIFICITY OF THE MOLECULAR DIAGNOSTIC METHOD FOR IDENTIFICATION OF APHANOMYCES ASTACI [PDF]
Knowledge and Management of Aquatic Ecosystems, 2007 A recent PCR-test developed for identification of Aphanomyces astaci, the organism responsible for crayfish plague, provided false positives for Aphanomyces frigidophilus, Aphanomyces repetans, and some Saprolegnia spp. Real-time PCR showed that with the

Recovering Turkish narrow clawed crayfish (Astacus leptodactylus) populations carry Aphanomyces astaci [PDF]
Knowledge and Management of Aquatic Ecosystems, 2012 Crayfish stocks collapsed in Turkey in mid 1980’s due to crayfish plague epidemics, with up to 25% survival in some cases. The collapsed stocks have then recovered slowly and commercial crayfish fishery was reinitiated gradually ...
