Plain-English summary
A dog in Brazil was diagnosed with Chagas disease after showing signs of multisystem failure, which means multiple organs were not working properly. Tests revealed the presence of the Trypanosoma cruzi parasite in the dog's blood and other tissues. Unfortunately, despite the diagnosis, the dog did not survive. This case highlights the importance of awareness about Chagas disease in pets, especially in areas where it is common, as dogs can spread the infection to humans.

Abstract
SUMMARY It is estimated that about 10 million people are infected with Trypanosoma cruzi worldwide, mostly in Latin America and more than 25 million are at risk of acquiring this infection in endemic areas. Dogs are an important reservoir for this pathogen and thus, considered a risk factor for human populations. This report describes one case of Chagas disease in a dog from Cuiabá, Mato Grosso State, Brazil. The diagnosis was obtained by direct examination of trypomastigote forms in blood smears. Amastigotes forms were visualized in microscopy of the bone marrow, lymph nodes, kidneys, liver and brain. The T. cruzi (ZIII) infection was confirmed by Polymerase Chain Reaction, and sequencing. The animal presented multisystemic failure and died. Although acute Chagas disease in humans is not reported in Cuiabá, this is the first report of a canine case in this region. This case represents a warning, to health professionals and authorities, to the possibility of transmission of this zoonosis in Cuiabá.
