Plain-English summary
A dog in Peru was brought to the vet with severe symptoms and sadly passed away due to an infection caused by a parasite called Trypanosoma evansi. Tests showed the parasite was present in the dog's blood and caused significant damage to vital organs like the heart, lungs, kidneys, and spleen. This case is significant as it marks the first reported instance of this type of infection in dogs in Peru, highlighting the need for better monitoring and prevention strategies for this disease in both pets and livestock.

Abstract
This study presents the first case report of canine trypanosomiasis caused by Trypanosoma evansi in Peru. The case was admitted to a veterinary clinic in the Peruvian Amazon region of San Martin with severe clinical symptomatology which resulted in the dog's death. Microscopy screening showed the presence of trypomastigotes in blood and bone marrow and postmortem histopathology found damage at the cardiac, lung, kidney and spleen levels. Collected specimens were tested by nested-PCR which were positive for Trypanosoma spp., but negative for T. cruzi. High-throughput sequencing determined that the infecting species was closely related to T. equiperdom/evansi and subsequent phylogenetic analysis confirmed that the sample was related to T. evansi. The presence of T. evansi in the area highlights the need for increased surveillance to assess the impact of surra in the region and to develop measures to prevent socioeconomic damage resulting from infections in domestic and farm animals as well as prevent zoonotic transmission.
