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

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.

Confirmation of crayfish plague in Italy: detection of Aphanomyces astaci in white clawed crayfish [PDF]

Diseases of Aquatic Organisms, 2010
In the summer of 2009, high levels of mortality among white clawed crayfish Austropotamobius pallipes were observed in 3 watercourses of central Italy. PCR and culture methods were used to detect the causative agent of the disease. Two strains of Aphanomyces spp.

A Comprehensive Review on Crustaceans’ Immune System With a Focus on Freshwater Crayfish in Relation to Crayfish Plague Disease [PDF]

Frontiers in Immunology, 2021
Freshwater crayfish immunity has received great attention due to the need for urgent conservation. This concern has increased the understanding of the cellular and humoral defense systems, although the regulatory mechanisms involved in these processes ...

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

The North American crayfish Procambarus clarkii is the carrier of the oomycete Aphanomyces astaci in Italy [PDF]

Biological Invasions, 2010
Aphanomyces astaci (Saprolegniales, Oomycetes) is classified among the 100 world’s worst invasive species. This species is endemic to North America and has been introduced into Europe by imports of their hosts, the North American crayfish species. As a consequence, extensive mass mortalities involved several populations of the European crayfish.

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 ...

Seasonality affects key physiological pathways in Pontastacus leptodactylus during an Aphanomyces astaci epidemic outbreak [PDF]

Scientific Reports
Freshwater crayfish Pontastacus leptodactylus is an indigenous European species of considerable ecological and commercial significance. However, it is highly susceptible to the oomycete Aphanomyces astaci, the causative agent of crayfish plague. Although

New Insight into the Crayfish Procambarus clarkii (Girard, 1852) (Crustacea, Cambaridae): A Morphometric Combined Approach to Describe the Case of a Mediterranean Population [PDF]

Animals
We adopted a morphometric approach to provide statistical support for the description of two different morphotypes (I, reproductive, II, non-reproductive) firstly observed in Procambarus clarkii specimens caught in a population from Sardinia Island ...

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.

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 ...
