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

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

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 ...

Cuticular Swabs and eDNA as Non-Invasive Sampling Techniques to Monitor Aphanomyces astaci in Endangered White-Clawed Crayfish (Austropotamobius pallipes Complex) [PDF]

Diversity, 2023
In endangered crayfish conservation projects, it is paramount to map the distribution of the causative agent of crayfish plague, Aphanomyces astaci, in native populations. Considering the inapplicability of the destructive cuticular sampling protocol for

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.

Resistance to the crayfish plague, Aphanomyces astaci (Oomycota) in the endangered freshwater crayfish species, Austropotamobius pallipes. [PDF]

PLoS ONE, 2017
The pathogen Aphanomyces astaci Schikora 1906 is responsible for the decline of the native crayfish species of Europe, and their current endangered status. This pathogenic species is native to North America and only colonizes aquatic decapods.

Dataset of the de novo assembly and annotation of the marbled crayfish and the noble crayfish hepatopancreas transcriptomes [PDF]

BMC Research Notes, 2022
Objectives Crayfish plague disease, caused by the oomycete pathogen Aphanomyces astaci represents one of the greatest risks for the biodiversity of the freshwater crayfish.

Resistance to Crayfish Plague: Assessing the Response of Native Iberian Populations of the White-Clawed Freshwater Crayfish [PDF]

Journal of Fungi, 2022
Crayfish plague, caused by the oomycete pathogen Aphanomyces astaci, is one of the most devastating of the emerging infectious diseases. This disease is responsible for the decline of native European and Asian freshwater crayfish populations.

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 ...
