| BACKGROUND: Skin nodules of O. fasciata are a common finding in dromedary camels, though with a minimal clinical impact. There is little information about the molecular pathological impact of this parasite. OBJECTIVES: The present study was conducted to evaluate the prevalence and pathology of O. fasciata. METHODS: After their slaughter, 456 dromedary camels of different ages were carefully inspected individually for infection with O. fasciata nodules. Tissue samples were collected for histopathology, stained with hematoxylin and eosin whereas male and female specimens were fixed and morphologically examined. RESULTS: A total of 138 (30.26%) camels were infected with O. fasciata nodules one or several O. fasciata nodules 1.2-2.2 cm in diameter and 507-845 mg in weight were also identified in the infected animals. Moreover, histopathological investigations showed multiple granulomas, and different sections of Onchocerca l microfilariae were observed in the center of granulomas. The inflammatory reactions surrounding the parasites involved a large number of neutrophils and necrotic debris followed by lymphocytes, macrophages, epithelioid, giant cells and connective tissues, respectively. CONCLUSION: The present study found a high prevalence of onchocerciasis in the skin lesions of the camels in Iran. Therefore, the result of our study can be used for preventive measures and reduce economic losses caused by the parasite. | ||
