Parasitic Infections of Wild Boars (Sus scrofa) in Iran: A Literature Review

Background: Swine species are an important source of meat production worldwide, except in Islamic countries where pig breeding and pork consumption are forbidden. Hence, they are often neglected in these regions. A considerable number of wild boars (Sus scrofa) inhabit Iranian territories, particularly in dense forests of north, west and southwest of the country, but our knowledge regarding their parasites is very limited. Objective: The lack of a comprehensive record in this connection encouraged us to review the whole works of literature in the country. Methods: The current review presents all the information about the parasitic diseases of wild boar in Iran extracted from articles available in both Persian and English databases until June 2017. Results: So far, 8 genera of protozoa (Toxoplasma, Balanthidium, Tritrichomonas, Blastocystis, Entamoeba, Iodamoeba, Chilomastix and Sarcocystis) and 20 helminth species, including four cestode species, two trematode species, thirteen nematode species as well as a single species of Acanthocephala have been described in Iranian wild boars. Conclusion: This review sheds light on the veterinary and public health aspects of the parasitic diseases of wild boars in the country and alerts authorities for future preventive measures.
