“…Due to close morphological similarities, molecular phylogenetic approaches have been used extensively in association with traditional morphological techniques as reliable methods for confirmation of accurate identification, and differentiation between pinworms infect-ing laboratory rodents (Jacobs et al, 1997;Zhu et al, 1998;Vermund and Wilson, 2000;Morales-Hojas et al, 2001;Nakano et al, 2006;Li et al, 2007;Zhu et al, 2007;Chang et al, 2009). In the present study, a nuclear rDNA region of the recovered parasite species was amplified using the species-specific primers Nem 18SF/Nem 18SR, designed by Floyd et al (2005).…”
