The crayfish plague fungus(Aphanomyces astaci)in Spain [PDF]
Depuis 1978, une serie d'epizooties correspondant a la «peste» des ecrevisses, dont l'agent responsable est le champignon Aphanomyces astaci, s'est produite en Espagne. En consequence, la plupart des populations de l'ecrevisse patrimoniale Austropotamobius pallipes a ete decimee par cette maladie. Cet article decrit l'etat actuel de la maladie dans les

Detection of Aphanomyces astaci in North American crayfish by polymerase chain reaction [PDF]
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
