Phylogenetic tree based on an alignment of a 352 bp region of the NAD1 mitochondrial gene from Taenia species, including 7 sequences derived from isolates from cats in the current study. The tree is a consensus of 100 bootstrap iterations of neighbor-joined trees created from distance matrices calculated using the F84 option in dnadist. The tree is rooted with Echinococcus felidis, and nodes with bootstrap values of > 50% are indicated. Province of origin of the study sequences is indicated by either SK (Saskatchewan) or AB (Alberta), and GenBank accession numbers are indicated in parentheses.
