In this paper, European common toad (Bufo bufo), European green toad (Bufo viridis) and marsh frog (Rana ridibunda) were collected in Canakkale Province (northwestern Turkey) between 2000 and 2003, and examined for helminths. Three of three (100%) B. bufo, 22 of 22 (100%) B. viridis, and 13 of 14 (92.86%) R. ridibunda were infected with one or more helminths. The helminths of B. bufo included two nematodes (Cosmocerca ornata and Oxysomatium brevicaudatum). The helminth fauna of B. viridis comprised six species: one species of monogenca (Polystoma viridis), one species of digenea (Pleurogenoides medians), one species of cestode (Nematotaenia dispar) and three species of nematodes (Oswaldocruzia filiformis, Cosmocerca ornata, and Oxysomatium brevicaudatutn). The helminth fauna of R. ridibunda comprised seven species: five species of trematodes (Diplodiscus subclavatus, Gorgodera cygnoides, G. vitelliloba, Bracylwoelium salamandrae and P. medians), and two species of nematodes (C. ornata, and O. brevicaudatum). Cosmocerca ornata and O. brevicaudatum were collected from three host species, and P. medians was recorded a second time from B. viridis in Turkey.
