ABSTRACT

The incidence and intensity of metazoan parasites in 3 species of Iraqi amphibians were studied. The amphibians were Rana ridibunda, Bufo viridis and Hyla arborea. Twenty-four species of helminths were encountered, including 16 trematodes, 1 cestode and 7 nematodes. Their respective names are: Polystoma integerrimum, Prosotocus confusus, P. fuelleborni, Pleurogenoides gastroporus, P. medians, Sonsinotrema tacapense, Opisthioglyphe ranae, Haplometra cylindracea, Haematoloechus volgensis, H. vitelloconfluentum, H. similis, H. asper, Gorgoderina vitelliloba, Gorgodera euzeti, G. amplicava, Nematotaenia dispar, Cosmocerca ornata, C. commutata, Aplectana acuminata, Aplectana sp., Oxysomatium sp., Ozwaldocruzia filiformis and Rhabdias bufonis. Collection localities, infection sites and rates and parasite burdens were determined throughout the species list. The highest and lowest rates of infection were for R. bufonis in B. viridis and O. ranae in R. ridibunda, while the highest and lowest worm burdens were for C. ornata in R. ridibunda and P. integerrimum in B. viridis. Seven of the species included in this study are thought to be new for Iraq.
