Phylogenetic context


The taxonomy of this species has been revised recently, and there is discussion as to whether the lab strain used by immunologists and parasitologists is H. polygyrus or H. bakeri. Additionally, some authors consider 'bakeri' to be a subspecies of H. polygyrus (i.e. H. p. polygyrus and H. p. bakeri)
