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.

Prevalence of the pathogen Aphanomyces astaci in freshwater crayfish populations in Croatia

open access: yesDiseases of Aquatic Organisms, 2016
The Oomycete Aphanomyces astaci is an obligate crayfish parasite that co-evolved with American crayfish species, and they therefore generally live in a balanced relationship. On the contrary, European native crayfish are highly susceptible to A. astaci, and infestation with it causes development of the lethal disease termed crayfish plague.

Survey of the crayfish plague pathogen presence in the Netherlands reveals a new Aphanomyces astaci carrier

open access: yesJournal of Invertebrate Pathology, 2014
North American crayfish species as hosts for the crayfish plague pathogen Aphanomyces astaci contribute to the decline of native European crayfish populations. At least six American crayfish species have been reported in the Netherlands but the presence of this pathogenic oomycete with substantial conservational impact has not yet been confirmed in the

Aphanomyces astaci genotypes involved in recent crayfish plague outbreaks in central Italy

Diseases of Aquatic Organisms, 2018
The oomycete Aphanomyces astaci is the causative agent of crayfish plague in native European freshwater crayfish. Molecular analyses showed that several distinct genotype groups of this pathogen, apparently associated with different original host taxa, are present in Europe.

Diversity and distribution of Aphanomyces astaci in a European hotspot of ornamental crayfish introductions

open access: yesJournal of Invertebrate Pathology
Ornamental trade has become an important introduction pathway of non-native aquatic species worldwide. Correspondingly, there has been an alarming increase in the number of established crayfish of aquarium origin in Europe over the previous decade. The oomycete Aphanomyces astaci, the pathogen causing crayfish plague responsible for serious declines of

Hostitelé a přenos původce račího moru Aphanomyces astaci [PDF]

open access: yes, 2015
The crayfish plague pathogen, the oomycete Aphanomyces astaci, has been decimating populations of European crayfish species for more than 150 years, and is therefore considered one of the 100 worst world's invasive species. A. astaci is highly specialised for a parasitic life, but it can be isolated from moribund crayfish and grown on synthetic media ...
