On the Adaptation of Aphanomyces astaci as a Parasite
Physiologia Plantarum, 1969AbstractThe crayfish plague parasite Aphanomyces astaci was compared with some other species of Aphanomyces in several physiological respects to detect signs of specialization in the plague fungus which could be connected with its life as a parasite.Thus, A. astaci showed good growth in crayfish serum in contrast to the other species.

Aphanomyces astaci genotypes involved in recent crayfish plague outbreaks in central Italy
Diseases of Aquatic Organisms, 2018The oomycete Aphanomyces astaci is the causative agent of crayfish plague in native European freshwater crayfish. Molecular analyses showed that several distinct genotype groups of this pathogen, apparently associated with different original host taxa, are present in Europe.

Mycoplasma-Like Structures in the Aquatic Fungus Aphanomyces astaci
Science, 1974The hyphae of a nonzoosporulating strain of Aphanomyces astaci contain numerous structures which most closely resemble published micrographs of certain mycoplasmas. Two normal strains of the same species do not contain these mycoplasma-like bodies.

Aphanomyces astaci: isolation and culture
Journal of Fish Diseases, 1986Abstract. Methods for the isolation and culture of Aphanomyces astaci, the causative organism of crayfish plague, are presented. The sensitivity of the pathogen to various antimicrobial agents was investigated, and a combination of penicillin G and oxolinic acid was chosen to provide a selective medium for isolation. A full description of the pathogen

Wound reactions and Aphanomyces astaci growth in crayfish cuticle
Journal of Invertebrate Pathology, 1980Abstract Superficial wounding of crayfish soft cuticle by removal of the epicuticle caused hemocyte aggregation beneath the wound. The aggregation seemed to be induced by osmotic factors. Subsequently, melanin was only formed in parts of the wound region.

Prevalence of the pathogen Aphanomyces astaci in freshwater crayfish populations in Croatia
Diseases of Aquatic Organisms, 2016The Oomycete Aphanomyces astaci is an obligate crayfish parasite that co-evolved with American crayfish species, and they therefore generally live in a balanced relationship. On the contrary, European native crayfish are highly susceptible to A. astaci, and infestation with it causes development of the lethal disease termed crayfish plague.

Physiological Variation in Strains of Aphanomyces astaci
Physiologia Plantarum, 1971AbstractPhysiological variation was found both between and within strains of the crayfish plague fungus, Aphanomyces astaci, in culture.The loss of capacity to produce spores was irreversible while losses of motility and virulence to the crayfish were reversible changes.

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 ...

Resistance to the crayfish plague pathogen, Aphanomyces astaci, in two freshwater shrimps
Journal of Invertebrate Pathology, 2014Aphanomyces astaci, the causal agent of the crayfish plague, has recently been confirmed to infect also freshwater-inhabiting crabs. We experimentally tested the resistance of freshwater shrimps, another important decapod group inhabiting freshwaters, to this pathogen.
