AbstractThis study was conducted to investigate Anoplocephalidia Cestoda in sheep and goat and evaluate the 18s rRNA to genetically differentiate the genera of this family. Sixty sample tapeworms were collected from small intestines of 30 sheep and 30 goats from different slaughterhouses in Al-Najaf and Al-Qadisiyah provinces, during September, 2016 to February, 2017. Based on polymerase chain reaction (PCR) and 18s rRNA gene partial sequencing (18sGPS) methods used, tapeworm infection of sheep and goat’s intestines was 32.9% and 31.4%, respectively. The partial gene sequencing of the 18S rRNA gene showed two closely related isolates of M. benedeni which are aligned distinctly to an NCBI isolate of the same species from China. For T. giardia, the outcomes of the phylogenetic analysis unveiled three distinct local isolates which were similar to an NCBI database isolate from China. The current data ensure the importance of the molecular techniques in differentiating between Thysaniezia (Helictometra) giardi and Moniezia species that were identified for their presence in the small intestines of sheep and goats.
