Table 3. Prevalence of T. cruzi infection in the most sampled alternative host species.

Host species	Species grouping	Number of records	Mean prevalence (%)

The total number of specimens tested is given in parentheses after the number of records, and the full range of prevalence values is given in parentheses after the mean prevalence value.
