Percentage identity of Tci-pgp-9-IBDA sequence variants.

The percentage identity between the Tci-pgp-9-IBDA sequence variants from the UK and NZ strains of T. circumcincta were calculated from the number of base substitutions per site from between sequences. Analyses were conducted in MEGA7 (Kumar et al., 2016), using the Kimura 2-parameter model (Kimura, 1980). Fewer than 5% alignment gaps, missing data and ambiguous bases were allowed at any position. The sequence variants with the identity >95% (shaded) formed the basis for the numbered classification of the corresponding UK sequence variants. Note that UKv11-UKv14 had no corresponding NZ variant with >90% identity.
