Phylogenetic relationship of the pinworms of the genus Syphacia from murines of Indonesia and some other regions inferred by molecular analysis

Sequencing of partial cytochroine c oxidase subunit 1 gene (Cox-1) of initochondrial DNA and 28S ribosomal RNA gene (rDNA) of nuclear DNA was attempted for pinworms of the genus Syphacia from murines of Indonesia in order to compare with those from other regions. Cox-1 sequence of Syphacia rifaii from Bunomys penitus of Sulawesi was characteristic by having deletions of three consecutive nucleotides at two loci in addition to numerous substitutions, rcsulting in very long branch in phylogenetic trees. Nevertheless, both in Cox-1 and 28S rDNA trees, S. rifaii formed a clade with Syphacia muris. Three Syphacia species parasitic in Apodemus, Syphacia emileromani, Syphacia stroma and Syphacia agraria, formed one clade in 28S rDNA phylograms, suggesting co-evolutionary relationship with their hosts. Indonesian examples of S. muris were rather diverged from those in the laboratory rats, Rattus norvegicus, both in Cox-1 and 28S rDNA, presumably reflecting the process of geographical dispersal or host Rattus spp. with this pinworm over the world.
