Summary of field samples collected by location and species, the number of confirmed positive infections (+), the percentage of samples identified as positive (in parentheses), and the corresponding number of sequences used (n) in diversity and phylogenetic analyses (i.e. sequences used = the number of sequences with bi-directional coverage of 386 base pairs and no ambiguous bases) are indicated.
