Table 2 Trypanosoma cruzi natural infection in free-living wild mammals from the Amazon Forest biome: taxonomic identification of the examined mammals, results of hemocultures, indirect immunofluorescence tests and characterization of parasites. In the case of insufficient blood for hemocultures and serological tests, we prioritized the blood cultures
