Abstract:

A field trials were conducted to assess the helminth parasites of ۱۲ marsh frogs (Rana ridibunda ridibunda) in the Anzali, Astara and Aghbaba regions in the north of Iran in May ۱۹۹۴. Experimental results showed that ۸۳.۸% of the Anzali marsh frogs were infected by one or two kinds of metacercarian cysts of digenetic trematodes. The helminth parasites were included Skrjabinoeces breviansa, S. smilis, Gorgodera dollfusi, Opisthioglyphe ranae, Prosotocus confusus, Encyclometra colubrimurorum and Codonocephalus urniger. Frogs collected from the Astara region was infected by the helminth parasites such as Diplodiscus subclavatus, P. confusus, C. urniger and Cosmocerca ornata. There were only one digenetic trematodes cysts such as Pleurogenoides medians in the Aghbaba region. In this paper, except the S. smilis, C. urniger and O. ranae we report ۷ new helminth parasites in the north Iranian freshwater system for the first time.
