title: Comparative analyses of the complete mitochondrial genomes of the two murine pinworms Aspiculuris tetraptera and Syphacia obvelata.
abstract: Pinworms Aspiculuris tetraptera and Syphacia obvelata are important parasitic nematodes of laboratory mice, rat and other rodents. However, the mitochondrial (mt) genome of these parasites have not been known yet. In the present study, the complete mt genomes of A. tetraptera and S. obvelata were sequenced, which were 13,669 bp and 14,235 bp in size, respectively. Both genomes included 12 protein-coding genes, two rRNA genes, 22 tRNA genes and one non-coding region. The mt genomes of A. tetraptera and S. obvelata preferred bases A and T, with the highest for T and the lowest for C. The mt gene arrangements of the two pinworms were the same as that of the GA8 type. Phylogenetic analysis using mtDNA data revealed that the Bayesian inference (BI) trees contained two big branches: species from Oxyuridomorpha, Rhabditomorpha and Ascaridomorpha formed one branch, and those from Spiruromorpha formed another branch with high statistical support. The two murine pinworms A. tetraptera and S. obvelata have closer relationship than to other pinworms. This study provides a foundation for studying the population genetics, systematics and molecular phylogeny of pinworms.
