Nucleotide sequences of the second internal transcribed spacer region (ITS-2) of nuclear ribosomal DNA in Н. contortus and H. placei revealed six (2.6%) nucleotide differences between these two species. The level of the intraspecific difference in ITS-2 in Haemonchus was low. A number of morphological differences together with distinctive ITS-2 sequences signatures at the molecular level clearly differentiate H. placei from Н. contortus in the genus Haemonchus.
