First European Interlaboratory Ring Test Study to Detect DNA of Crayfish and the Crayfish Plague Pathogen From Water Samples

Environmental DNA
In recent years, European countries have intensified efforts to control or limit the spread of invasive freshwater crayfish and the crayfish plague pathogen Aphanomyces astaci, while working to conserve native species such as the noble crayfish (Astacus ...

Long-term changes in the prevalence of the crayfish plague pathogen and its genotyping in invasive crayfish species in Czechia [PDF]

NeoBiota, 2022
The widespread presence of North American alien crayfish in Europe is a major driver of native crayfish population declines, mainly because they are chronic carriers of the oomycete Aphanomyces astaci responsible for crayfish plague.

Differentiation and Pathogenicity within the Saprolegniaceae [Elektronisk resurs] : Studies on Physiology and Gene Expression Patterns in Saprolegnia parasitica and Aphanomyces astaci

, 2001
Saprolegnia parasitica and Aphanomyces astaci are parasitic water moulds belonging to the Oomycetes. Despite their importance as parasites they are very little studied at the molecular level and the work described in this thesis was aimed at increasing ...

Coexistence of Two Invasive Species, Procambarus clarkii and Aphanomyces astaci, in Brackish Waters of a Mediterranean Coastal Lagoon

Frontiers in Ecology and Evolution, 2021
Procambarus clarkii is a worldwide freshwater invasive crustacean from North America and was first introduced into Europe the 1970s. Along with P. clarkii, another invasive alien species was also spreading: Aphanomyces astaci.

Controlled Infection Experiment With Aphanomyces astaci Provides Additional Evidence for Latent Infections and Resistance in Freshwater Crayfish

Frontiers in Ecology and Evolution, 2021
For 150 years the crayfish plague disease agent Aphanomyces astaci has been the cause of mass mortalities among native European crayfish populations. However, recently several studies have highlighted the great variability of A.

Preliminary survey of Aphanomyces sp. associated with native and invasive crayfish in the Lower Susquehanna watershed of South Central Pennsylvania

Journal of Freshwater Ecology, 2020
The oomycete species, Aphanomyces astaci, is well known as the devastating causal agent of European crayfish plague. Despite assumptions of a North American origin, the prevalence and distribution of A. astaci in its presumed native range is unknown.

Exploring the eDNA dynamics of the host-pathogen pair Pacifastacus leniusculus (Decapoda) and Aphanomyces astaci (Saprolegniales) under experimental conditions [PDF]

NeoBiota, 2022
The oomycete Aphanomyces astaci causes crayfish plague, a disease threatening native European crayfish. It is carried and transmitted by American crayfish species, which are the original hosts of A. astaci.

First record of the stone crayfish in the Romanian lowlands

Knowledge and Management of Aquatic Ecosystems, 2021
The stone crayfish is a native European freshwater species with significant population declines caused by anthropogenic pressure onto its habitats, climate change and spreading of non-indigenous invasive crayfish and their pathogens (e.g., Aphanomyces ...

May atyid shrimps act as potential vectors of crayfish plague? [PDF]

NeoBiota, 2019
The causative agent of crayfish plague, Aphanomyces astaci Schikora, was long considered to be a specialist pathogen whose host range is limited to freshwater crayfish.
