Maximum Likelihood phylogenetic tree depicting the relationships of the Spirometra isolate from a captive meerkat (Case 1; MH350843) from the United States, and isolates of Spirometra from various hosts worldwide based on a fragment of the cytochrome c subunit 1 gene. Branches with less than 50% bootstrap support were collapsed. Bootstrap support shown besides branches are based on 1000 replicates. When available, common name of animal host and geographic origin are included following GenBank accession number. ARG = Argentina, AUS = Australia, BRA = Brazil, CHI = China, ETH = Ethiopia, FIN = Finland, IND = India, INDO= Indonesia, IRA = Iran, JAP = Japan, KOR = South Korea, NZE = New Zealand, POL = Poland, SSU = South Sudan, TZN = Tanzania, UKR = Ukraine, USA = United States of America, VEN = Venezuela, VIET= Vietnam.
