Order Artiodactyla

Mammals from this order are rarely studied in the wild concerning their putative role played on the transmission cycle of T. cruzi. Despite that, a study conducted in the Pantanal region of Brazil observed an interesting situation represented by the feral pig (Fig. 11.7), which are domestic pigs (Sus scrofa) that returned to the wild environment in the Brazilian Pantanal: these animals were infected with the DTU TcI genotype of Trypanosoma cruzi and described as important maintenance reservoir hosts of the parasite in nature.80 In the same study, two sympatric species of wild boar (Tayassu tajacu and Tayassu pecari) were also found infected, as demonstrated by the presence of anti-T. cruzi antibodies in their serum.
