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

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

Confirmation of crayfish plague in Italy: detection of Aphanomyces astaci in white clawed crayfish [PDF]
Diseases of Aquatic Organisms, 2010 In the summer of 2009, high levels of mortality among white clawed crayfish Austropotamobius pallipes were observed in 3 watercourses of central Italy. PCR and culture methods were used to detect the causative agent of the disease. Two strains of Aphanomyces spp.

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

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.

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.
