The study of helminth parasites of Ranidae (Amphibia: Anura) from the vicinity of Sanandaj

The amphibians are an important class in the vertebrates with great role in the ecosystem. Their health will be affected by many factors such as the habitat distraction, climate changes and pathogens. There are reports of pathogenicity by helminth parasites in the frogs. More than ۲۰ species of Monogenea, Digenea, Cestoda and Nematoda have been reported from amphibians of Iran. The most reports are on the two common species in the region, the marsh frog, pelophylax ridibundus (Pallas, ۱۷۷۱) and green toad, Bufo viridis (Laurenti, ۱۷۶۸). The aim of the study is to investigate the fauna of helminth parasites in the family Ranidae around Sanandaj. So far, a total of ۳۰ specimens of marsh frogs were collected from different stations of the region in the summer and fall ۲۰۲۰. All organ systems of the hosts were examined for the parasites. To study morphological features, the digenean were examined as permanent mounts and nematodes as temporary mounts. The prevalence of infection for a species of oxurid nematode, Pharyngodonidae in the rectum was ۱۰۰%. In addition, two species of digenean trematode were found, one in the lungs and other in the intestine. The identification of parasite taxa to species level is carrying out.
