摘要: Sequences of the first internal transcribed spacer rDNA were characterised for four veterinary important species gastrointestinal nematodes from genus Nematodirus. The sequence data combined with previously published second to determine whether these regions provided a suitable number informative characters phylogenetic relationships within genus. A total 32 alignment positions set and 33 in analyses. Irrespective each analysed separately or combined, only one most parsimonious tree was produced, fully resolved. In addition, several conservatism among Nematodirus suggests that this region may also provide information higher taxonomic levels Molineoidea.
