Diversity of Trichinella species in relation to the host species and geographical location

摘要

Trichinella nematodes still circulate in various hosts in both domestic and sylvatic environments. Recently, in Europe, the transmission of Trichinella spp. to humans has been attributed more to wild animals than to domestic animals. However, domestic animals could still be a source of human infections in some regions. Therefore, our aim was to determine the species composition of Trichinella and the prevalence and intensity of infections in animal populations from the domestic cycle, namely pigs (Sus scrofa f. domestica); the synantropic cycle, in the form of rats (Rattus norvegicus); and the sylvatic cycle, namely wild boars (Sus scrofa) and red foxes (Vulpes vulpes), in Poland.
