Detection of Aphanomyces astaci in North American crayfish by polymerase chain reaction [PDF]

Diseases of Aquatic Organisms, 2006
We present a PCR based method to detect Aphanomyces astaci in North American crayfish. Primers were designed to specifically amplify parts of the internal transcribed spacer (ITS) regions and the 5.8 rRNA gene of A. astaci. A single round and a semi-nested assay were tested for their sensitivity and specificity. Specificity of the PCR assays was tested

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 ...

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 ...

Simultaneous detection of native and invasive crayfish and Aphanomyces astaci from environmental DNA samples in a wide range of habitats in Central Europe [PDF]

NeoBiota, 2020
Crayfish of North American origin are amongst the most prominent high-impact invasive invertebrates in European freshwaters. They contribute to the decline of European native crayfish species by spreading the pathogen causing crayfish plague, the ...

The crayfish plague fungus(Aphanomyces astaci)in Spain [PDF]

Bulletin Français de la Pêche et de la Pisciculture, 1997
Depuis 1978, une serie d'epizooties correspondant a la «peste» des ecrevisses, dont l'agent responsable est le champignon Aphanomyces astaci, s'est produite en Espagne. En consequence, la plupart des populations de l'ecrevisse patrimoniale Austropotamobius pallipes a ete decimee par cette maladie. Cet article decrit l'etat actuel de la maladie dans les

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 ...

Invasive Chinese mitten crab (Eriocheir sinensis) transmits crayfish plague pathogen (Aphanomyces astaci)

Aquatic Invasions, 2014
The Chinese mitten crab ( Eriocheir sinensis) is a vector of the fatal crayfish plague pathogen (Aphanomyces astaci). Both species are listed among the worlds 100 worst invasive species. From its origin in China the Chinese mitten crab was introduced to Europe, presumably via ballast water from ships. A.

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 ...
