| Zusammenfassung: | © 2016 John Wiley & Sons Ltd. Systemic amoebiasis of sole is caused by Endolimax piscium, a cryptic parasitic archamoeba whose epidemiology and pathogeny are yet unknown. To establish reliable detection methods for this parasite, a battery of molecular diagnostic tools (ISH, PCR and qPCR) were developed and evaluated with a panel of clinical samples from symptomatic diseased fish and from apparently normal animals of different stocks. As there is neither enough background information on the epidemiology of the disease nor a validated reference method, comparison of tests used a composite reference method approach. The ISH technique was the most specific and sensitive in intestine samples and particularly useful as a reference confirmatory method, while the best method in muscle samples was qPCR. Application of the tests to asymptomatic fish demonstrated presence of parasites in a large proportion (>25%) of their intestines, suggesting that this is the point of entry of the amoebae and the initial stage in the development of the disease. The triggering factors that facilitate the breaching of the intestinal barrier by E. piscium, causing granulomatous lesions in other organs and systemic spreading, are not completely understood but our results point to the connective tissue as a preferential target for parasite development and migration |
