The introduction and dissemination of this pathogen is attributed to the spread of invasive North American crayfish, which can act as carriers for <jats:italic>A. astaci<\/jats:italic>. As native European crayfish often succumb to infection with <jats:italic>A. astaci<\/jats:italic>, determining the prevalence of this pathogen in non-native crayfish is vital to prioritize native crayfish populations for managed translocation. In the current study, 23 populations of invasive signal crayfish (<jats:italic>Pacifastacus leniusculus<\/jats:italic>) from the UK were tested for <jats:italic>A. astaci<\/jats:italic> presence using quantitative PCR. Altogether, 13 out of 23 (56\u00b75%) populations were found to be infected, and pathogen prevalence within infected sites varied from 3 to 80%. Microsatellite pathogen genotyping revealed that at least one UK signal crayfish population was infected with the <jats:italic>A. astaci<\/jats:italic> genotype group B, known to include virulent strains. Based on recent crayfish distribution records and the average rate of signal crayfish population dispersal, we identified one native white-clawed crayfish (<jats:italic>Austropotamobius pallipes<\/jats:italic>) population predicted to come into contact with infected signal crayfish within 5 years. This population should be considered as a priority for translocation.<\/jats:p>","DOI":"10.1017\/s0031182016002419","type":"journal-article","created":{"date-parts":[[2017,1,12]],"date-time":"2017-01-12T09:51:18Z","timestamp":1484214678000},"page":"411-418","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":17,"title":["The prevalence of <i>Aphanomyces astaci<\/i> in invasive signal crayfish from the UK and implications for native crayfish conservation"],"prefix":"10.1017","volume":"144","author":[{"given":"J.","family":"JAMES","sequence":"first","affiliation":[]},{"given":"S.","family":"NUTBEAM-TUFFS","sequence":"additional","affiliation":[]},{"given":"J.","family":"CABLE","sequence":"additional","affiliation":[]},{"given":"A.","family":"MRUGA\u0141A","sequence":"additional","affiliation":[]},{"given":"N.","family":"VI\u00d1UELA-RODRIGUEZ","sequence":"additional","affiliation":[]},{"given":"A.","family":"PETRUSEK","sequence":"additional","affiliation":[]},{"given":"B.","family":"OIDTMANN","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2017,1,12]]},"reference":[{"key":"S0031182016002419_ref59","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0587.2002.250107.x"},{"key":"S0031182016002419_ref58","unstructured":"Weinl\u00e4nder M. and F\u00fcreder L.
