Classic Trypanosoma cruzi, which is transmitted through excrement from the Reduviid or 'kissing bug' found throughout S. America. Key differentiating features from African trypanosomes (T. rhodesiense and T. gambiense) include the very enlarged posterior kinetoplast, the curved 'C' shape and geography.

T. cruzi. The periorbital swelling indicates proliferation of the amastigotes at that site.
