First case of Trichinella nativa infection in wild boar in Central Europe—molecular characterization of the parasite

The examination of wild boars gained in Poland shows for the first time occurrence of Trichinella nativa, freeze-resistant species of Trichinella in this host from the central Europe region. This finding is not only one of several cases of T. nativa invasion in wild boars all over the world but also one of the very few cases of T. nativa detected so far beyond the known boundary of occurrence of this species. The molecular characterization of discovered larvae based on analysis of partial genes: 5s rDNA-ISR and CO1 confirm the findings. Moreover, the analyzed DNA sequences of both genes present new haplotypes of T. nativa in comparison to that described previously.
