Microscopy screening showed presence trypomastigotes blood and bone marrow postmortem histopathology found damage at cardiac, lung, kidney spleen levels. Collected specimens were tested nested-PCR positive for spp., but negative T. cruzi. High-throughput sequencing determined that infecting species closely related equiperdom/evansi subsequent phylogenetic analysis confirmed sample evansi. area highlights need increased surveillance assess impact surra develop measures prevent socioeconomic resulting from infections domestic farm animals as well zoonotic transmission.
