First Molecular Characterization of Aspiculuris tetraptera (Nematoda: Heteroxynematidae) from Mus musculus (Rodentia: Muridae) in India.

Mus musculus (Rodentia: Muridae) were infected by a nematode belonging to the order Oxyurida. According to external morphological characters it was found to be Aspiculuris tetraptera Schulz, 1924. Present communication deals with molecular characterization of A. tetraptera infecting intestine of Mus musculus in Meerut (U.P.), India. A partial sequence of 18S ribosomal and cytochrome c oxidase subunit 1 (Cox 1) mitochondrial DNA analyses were performed. Sequence corresponding to 18S rRNA and mt Cox 1 gene was identical to sequences reported for A. tetraptera on GenBank. These results confirm the taxonomic validation of A. tetraptera parasitizing Mus musculus. This is the first report of molecular study of A. tetraptera in India.
