eDNA‐Based Detection of Invasive Crayfish and Crayfish Plague in Estonia

Environmental DNA
In Estonia, three invasive North American crayfish species—Pacifastacus leniusculus, Faxonius limosus, and Procambarus virginalis—have been detected through the annual monitoring program.

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.

Aphanomyces astaci in Mexico: a new haplotype from dwarf crayfish Cambarellus montezumae.

Journal of Invertebrate Pathology, 2023
The crayfish plague is an emerging infectious disease caused by the pathogen Aphanomyces astaci (Oomycota), which is responsible for the decimation of Eurasian freshwater crayfish. This pathogen can coexist with the North American crayfish. These are chronic carriers of the disease as consequence of an immune response that can contain the growth of the

May Cherax destructor contribute to Aphanomyces astaci spread in Central Europe

Aquatic Invasions, 2016
Transmission of the crayfish plague pathogen Aphanomyces astaci endangers native European crayfish. This pathogen, spread mainly by its natural hosts, North American crayfish, has also been detected in the aquarium trade in Europe.

Better Alone Than in Bad Company: Trophic Ecology of Co-Occurring Invasive and Native Crayfish. [PDF]

Ecol Evol
This study investigated and compared trophic interactions between invasive signal crayfish and native white‐clawed crayfish at sites of co‐occurrence and in allopatry. The presence of crayfish plague, body condition, and trophic niche traits were explored as possible factors that make invasive signal crayfish a strong competitor, enhancing its ...

Protocols for studying the crayfish plague pathogen, Aphanomyces astaci, and its host-pathogen interactions.

Journal of Invertebrate Pathology, 2023
The crayfish plague caused by the pathogen Aphanomyces astaci has decimated the European and Asian populations of freshwater crayfish and represents an important threat to the other highly susceptible crayfish species in the world, such as the Australian, Madagascar, and South American species.

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.

Host Resistance and Behavior Determine Invasion Dynamics of a Detrimental Aquatic Disease. [PDF]

Ecol Evol
To control emerging diseases, we need to understand the effects of variation in host resistance and the multitude of transmission modes of parasites combined with hosts' complex behavioral interactions. Based on a discrete stage model, we propose that even if the infection is fatal, coexistence of the host and the parasite can be facilitated by ...

Genomic Data Reveal Multiple Introduction Sources and Limited Post-Colonization Gene Flow in Southeast Michigan Invasive Red Swamp Crayfish (<i>Procambarus clarkii</i>). [PDF]

Ecol Evol
Examining the genetic patterns of invasive Red Swamp Crayfish in southeast Michigan, we found evidence of multiple separate introductions along with limited natural dispersal between geographic–genetic groups. We detected evidence of secondary dispersal from early invasive populations consistent with a bridgehead effect and little evidence the heavily ...

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.
