Plain-English summary
A study found that about 6.4% of dogs in Tennessee tested positive for exposure to Trypanosoma cruzi, the parasite that causes Chagas' disease. This was based on testing 860 dogs from various regions in the state. Factors like age, weight, and whether the dogs lived outdoors were linked to higher chances of exposure. While no differences were noted based on breed or sex, pet owners should be aware of the potential for Chagas' disease, especially if their dog shows symptoms like lethargy or heart issues. If you suspect your dog might be affected, it's important to discuss this with your veterinarian.

Abstract
Trypanosoma cruzi , the etiologic agent of Chagas' disease, is enzootic in animal populations of the southeastern United States. In the United States, T. cruzi prevalence has been reported for over 20 different wildlife species, and 7 autochthonous human cases have been documented since 1955. Previous canine (Canis familiaris) serosurveys have been limited either by small sample size or confined geographic reporting areas. In this study, we report a seroprevalence of 6.4% among 860 canines from 31 counties and 5 ecoregions throughout Tennessee, using an indirect immunofluorescent assay (IFA). Statistically significant associations between seropositivity and age, weight, and outdoor living were noted. Differences in seropositivity were not seen based on American Kennel Club (AKC) group, sex, habitat, land cover, and ecoregion. Greater attention should be given to possible T. cruzi transmission in Tennessee and veterinarians should consider Chagas' disease as a differential diagnosis with compatible signs.
