The number of sequences were obtained by cloning and sequencing from pooled DNA extracted from individual worms from each of the eight H. contortus populations.
The number of haplotypes and haplotype diversity (Hd) and nucleotide diversity (π) of partial β-tubulin isotype-1 gene sequences were defined using the program DnaSP5.1.
