Autochthonous spp. in European Mammals: A Brief Journey amongst the Neglected Trypanosomes.

The genus includes flagellated protozoa belonging to the family Trypanosomatidae (Euglenozoa, Kinetoplastida) that can infect humans and several animal species. The most studied species are those causing severe human pathology, such as Chagas disease in South and Central America, and the human African trypanosomiasis (HAT), or infections highly affecting animal health, such as nagana in Africa and surra with a wider geographical distribution. The presence of these species in Europe has been thus far linked only to travel/immigration history of the human patients or introduction of infected animals. On the contrary, little is known about the epidemiological status of trypanosomes endemically infecting mammals in Europe, such as in ruminants and in rodents and other sporadically reported species. This brief review provides an updated collection of scientific data on the presence of autochthonous spp. in mammals on the European territory, in order to support epidemiological and diagnostic studies on Trypanosomatid parasites.
