Investigation of ornamental crayfish reveals new carrier species of the crayfish plague pathogen (Aphanomyces astaci)

Aquatic Invasions, 2017
Several North American crayfish species have so far been identified as carriers of the crayfish plague agent Aphanomyces astaci. The pathogen is responsible for the declines of thousands of European crayfish populations. Currently, one of the introduction pathways of North American crayfish species is the aquarium trade which may sometimes be followed ...

Analysis of chitinase expression in the crayfish plague fungus Aphanomyces astaci [PDF]

Diseases of Aquatic Organisms, 2002
Chitinase, as determined by enzymatic activity in the growth medium and by transcription of the chitinase gene AaChi1, is expressed at a high level during vegetative growth of the crayfish pathogen Aphanomyces astaci and expression is not further stimulated by chitin. Expression is not detected in zoospores and it does not increase to high levels until

Investigation of the first recent crayfish plague outbreak in Ireland and its subsequent spread in the Bruskey River and surrounding areas

Knowledge and Management of Aquatic Ecosystems, 2022
White-clawed crayfish (Austropotamobius pallipes) is a keystone species found in western European freshwater bodies, where it has suffered drastic declines due to pathogens, competition with non-indigenous crayfish species (NICS) and habitat ...

Invasive crayfish and crayfish plague on the move: first detection of the plague agent Aphanomyces astaci in the Romanian Danube [PDF]

Diseases of Aquatic Organisms, 2012
Native European crayfish, such as Astacus leptodactylus, are threatened, among other factors, by the crayfish plague agent Aphanomyces astaci, dispersed by invasive North American crayfish. Two of these invaders, Pacifastacus leniusculus and Orconectes limosus, have extended their distribution in the River Danube catchment; the latter was detected for ...

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.

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 ...

First evidence of crayfish plague agent in populations of the marbled crayfish (Procambarus fallax forma virginalis)

Knowledge and Management of Aquatic Ecosystems, 2014
The introduction of non-indigenous species and associated diseases can cause declines in indigenous flora and fauna and threaten local biodiversity.

Chronic crayfish plague infection and eroded swimmeret syndrome in Lake Saimaa (Finland) signal crayfish [PDF]

Freshwater Crayfish, 2017
Abstract We present data and results from a 9-year survey (2009 – 2017) of the Lake Saimaa signal crayfish population in Finland. This population has a history of chronic infection with Aphanomyces astaci. It has now been discovered that female signal crayfish from Lake Saimaa suffer from various stages of eroded swimmeret syndrome (ESS), and male ...
