Recent acute crayfish mortality reveals Aphanomyces astaci presence in Bosnia and Herzegovina
Journal of Invertebrate Pathology, 2017Although the introduction of the crayfish plague pathogen Aphanomyces astaci to Europe is responsible for substantial declines in native crayfish populations throughout the whole continent, its presence has never been officially confirmed in many European regions, including most of the Balkan Peninsula. We demonstrate that the recent crayfish mortality

Ornamental trade has become an important introduction pathway of non-native aquatic species worldwide. Correspondingly, there has been an alarming increase in the number of established crayfish of aquarium origin in Europe over the previous decade. The oomycete Aphanomyces astaci, the pathogen causing crayfish plague responsible for serious declines of

Crayfish plague Aphanomyces astaci detected in redclaw crayfish, Cherax quadricarinatus in Taiwan
Journal of Invertebrate Pathology, 2016Between December 2013 and January 2014, five outbreaks of an unknown disease with moderate to high cumulative mortality were observed among the freshwater redclaw crayfish (Cherax quadricarinatus) populations at four crayfish farms in Miaoli and Changhua counties (northern Taiwan) and at one crayfish farm in Pingtung County (southern Taiwan ...

North American crayfish species as hosts for the crayfish plague pathogen Aphanomyces astaci contribute to the decline of native European crayfish populations. At least six American crayfish species have been reported in the Netherlands but the presence of this pathogenic oomycete with substantial conservational impact has not yet been confirmed in the

Aphanomyces astaci pathogenicity under laboratory and field conditions
Journal of Fish Diseases, 1987Abstract. The high pathogenicity of Aphanomyces astaci to susceptible crayfish has often been mentioned but not well investigated in publications on crayfish plague. This paper presents a study of that pathogenicity and considers the relationships between size of zoospore challenge and challenge temperature, which results in the extremely complex ...

Abstract In the crayfish, Astacus astacus , susceptible to the crayfish plague fungus, penetration of the cuticle by the parasite occurred in the soft cuticle. The zoospore lysed the surface lipid layer, tore it away, and formed an infection peg (germ tube) that penetrated through the epicuticle. A septum was formed in the infection peg, and a hypha

Studies on the Crayfish Plague Fungus Aphanomyces astaci
Physiologia Plantarum, 1966AbstractA mycelial suspension of the crayfish plague fungus, Aphanomyces astaci, was able to produce large numbers of zoospores, when transferred to redistilled water, at 20°C, even after storage for months at 2°C. Spore production was greater in redistilled water than in tap water and heavier under shake conditions than under stationary ones.

Hostitelé a přenos původce račího moru Aphanomyces astaci
2015The crayfish plague pathogen, the oomycete Aphanomyces astaci, has been decimating populations of European crayfish species for more than 150 years, and is therefore considered one of the 100 worst world's invasive species. A. astaci is highly specialised for a parasitic life, but it can be isolated from moribund crayfish and grown on synthetic media ...

Deciphering the mechanisms underlying the inhibition of Aphanomyces astaci by Pseudomonas
Pathogens enter complex interactions with a variety of microbes during their attempts to find and invade the host. Our aim was to investigate the effects of bacterial strains naturally associated with fish and crayfish on the oomycete pathogen Aphanomyces astaci (Oomycota), the causative agent of crayfish plague.Maguire, Ivana +4 more
