“…Reports of EM found in wild boars [21,22] were not considered sufficient for estimation of the design prevalence. However, wild boars are expected to be more exposed to EM than domestic pigs, hence it was decided to use twice the design prevalence of pigs, i.e .…”

BackgroundThe fox tapeworm Echinococcus multilocularis has foxes and other canids as definitive host and rodents as intermediate hosts. However, most mammals can be accidental intermediate hosts and the larval stage may cause serious disease in humans. The parasite has never been detected in Sweden, Finland and mainland Norway. All three countries require currently an anthelminthic treatment for dogs and cats prior to entry in order to prevent introduction of the parasite. Documentation of freedom from E. multilocularis is necessary for justification of the present import requirements.MethodsThe probability that Sweden, Finland and mainland Norway were free from E. multilocularis and the sensitivity of the surveillance systems were estimated using scenario trees. Surveillance data from five animal species were included in the study: red fox (Vulpes vulpes), raccoon dog (Nyctereutes procyonoides), domestic pig, wild boar (Sus scrofa) and voles and lemmings (Arvicolinae).ResultsThe cumulative probability of freedom from EM in December 2009 was high in all three countries, 0.98 (95% CI 0.96-0.99) in Finland and 0.99 (0.97-0.995) in Sweden and 0.98 (0.95-0.99) in Norway.ConclusionsResults from the model confirm that there is a high probability that in 2009 the countries were free from E. multilocularis. The sensitivity analyses showed that the choice of the design prevalences in different infected populations was influential. Therefore more knowledge on expected prevalences for E. multilocularis in infected populations of different species is desirable to reduce residual uncertainty of the results.

“…Neben den zum obligaten Wirtswechselzyklus zählenden Kleinnagern gibt es mittlerweile zahlreiche Berichte über so genannte Fehlzwischenwirte, in denen sich der Parasit nicht oder nur bedingt weiterentwickeln kann (Romig et al, 1999;Pfister et al, 1993). Dazu gehören beispielsweise Hausschwein, Wildschwein, Pferd und in wenigen dokumentierten Fällen auch der domestizierte Hund.…”

“…Histopathology is required for the confirmation of the aetiology of the lesions observed (Houin et al, 1982). Development of the larva is incomplete (no protoscolex) in some intermediate or aberrant hosts, as has been reported in pig and wild boar (Pfister et al, 1993;Sydler et al, 1998;Boucher et al, 2005;Deplazes et al, 2005). As an aid to diagnosis, identification of small or atypical lesions can be done using molecular biology or immunohistochemistry (Lightowlers and Gottstein, 1995;.…”
