[Importation of parasites by tourism and animal trading].
International transport of animals is associated with an enhanced risk of import of a number of parasite species that are not endemic in Germany. Pets accompany tourists on journeys all over the world, but in particular to southern Europe, and dogs are increasingly imported from (sub-)tropical countries for reasons of animal welfare. Veterinary practitioners are thus confronted with parasites that are unusual in their patients. The specific transmission routes determine whether an imported parasite is able to become endemic. Although parasites eradicated in Germany such as Trypanosoma equiperdum and Tritrichomonas foetus may be principally imported they are unlikely to re-establish due to the current epidemiological conditions. Imported animals that harbour parasites which may occur naturally but are currently rare in Germany are a potential source of increased infection risk. Certain areas in Germany have probably become endemic for Babesia canis and the respective vector tick Dermacentor reticulatus has been found. Whether other vector borne parasitic diseases such as leishmaniosis or heartworm disease have the potential to spread into Germany is still a matter of debate.
