Molecular detection of Aphanomyces astaci – An improved species specific qPCR assay
Journal of Invertebrate Pathology, 2023 The parasitic oomycete Aphanomyces astaci is the causative agent of crayfish plague, a devastating disease for European freshwater crayfish. Species specific quantitative real-time PCR (qPCR) can offer rapid detection of the pathogen. However, the well established A.
