ABSTRACT
Background and Aim: There is a large amount of information on intestinal parasites in stray dogs and golden jackals (Canis aureus) in Mazandaran Province, Iran. However, there is little information about foxes and wolves, which have a potential role in the spread of dangerous parasitic diseases, such as echinococcosis and toxocariasis. The aim of the present study was to identify the genus or species of parasitic worms in stool samples obtained from carnivores in Mazandaran Province, Iran, from August 2017 to April 2018.
Materials and Methods: A total of 274 fecal samples were collected from carnivores, including dog, fox, wolf, and C. aureus in three areas of Mazandaran Province, Iran. All specimens were examined by centrifugal fecal flotation using a solution of Sheather's sugar to detect helminths eggs. Then, all samples were assessed using a light microscope. Data analysis was performed by SPSS version. 18 (Chicago, IL, USA).
Results: In this study, seven genera of helminths were observed, including Ancylostoma, Uncinaria, Toxocara, Dipylidium, Toxascaris, Taenia, and Spirocerca. The prevalence of helminth infections was 97.7% (127 out of 130), 56.7% (51 out of 90), 51.4% (18 out of 35), and 52.6% (10 out of 19), among dogs, C. aureus, foxes, and wolves, respectively. The highest prevalence of Ancylostoma and Toxocara infections occurred in the eastern and central areas of the province (42.1% and 35.7%, respectively).
Conclusion: Based on the results of this study, the infection with intestinal zoonotic helminths in carnivores was an important public health factor in Mazandaran. Therefore, these infections can be potentially harmful to humans and other animals.
