Comparison of partial nucleotide sequence of the hypervariable region of cytochrome c oxidase subunit 1 (cox1). A Multiple sequence alignment of partial hypervariable cox1 region (A) with related sequences identified by species name and accession GenBank number. Only the fully overlapping region is shown (250 nt). Identical residues are depicted as dots. B Pairwise comparison of Eucoleus [Capillaria] sp. (cat) cox1 with related Capillaria spp. using both number of differences and percent identity. The calculation was based on the alignment region shown in A
