摘要: The present study characterised seven species of the Chabertiidae (Nematoda: Strongyloidea) belonging to either subfamily Oesophagostominae (Oesophagostomum radiatum, Oesophagostomum venulosum, dentatum, quadrispinulatum, columbianum, bifurcum) or Chabertiinae (Chabertia ovina) by their second internal transcribed spacer rDNA sequence, assessed extent intraspecific variation and interspecific differences in inferred phylogenetic relationship C. ovina with respect members Oesophagostominae. In both phenetic cladistic analyses sequence data, Chabertia was nested within Oesophagostomum, suggesting that examined represent same genus, alternatively, may more than one genus.
