Abstract
Debates continue over the extent to which the parasitic trichostrongyl ids Haemonchus placei and Haemonchus contortus hybridise in nature, an d whether they deserve species status. Mitochondrial ND4 gene sequence s from individuals of each putative species collected from populations around the United States indicate that the two species are highly dif ferentiated at the mtDNA level. Furthermore, there was no evidence of introgressive hybridisation occurring in wild populations. (C) 1997 Au stralian Society for Parasitology. Published by Elsevier Science Ltd.
