Evolutionary relationships based on the full-length VP1 sequences belonging to the types E19, E2, E12 and E24. The samples from this study are in red with their respective collection site. The other sequences are named by using their respective GenBank accession number, country (ISO 3166-1 alpha-3 codes) and year of sampling, when known; some lineages have been collapsed for better legibility. The evolutionary history was inferred in MEGA X by using the Maximum Likelihood method and Tamura-Nei model. Initial tree(s) for the heuristic search were obtained automatically by applying Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances estimated using the Tamura-Nei model, and then selecting the topology with superior log likelihood value. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches; bootstrap values < 90% were hidden
