N2  - Prevalence of trematode cercariae within freshwater snails at the Ross River reservoir is presented, with special attention to Trichobilharzia sp(p). (Digenea:Schistosomatidae), known causative agents of schistosome dermatitis. Three pulmonate snails-a lymnaeid, Austropeplea lessoni, and two planorbids, Gyraulus gilberti and Amerianna carinata-and one prosobranch snail, Thiara balonnensis, were common in the reservoir. These snails were infected with trematode cercariae representing six different families. Both Austropeplea lessoni (4.5%) and G. gilberti (1.8%) act as intermediate hosts of Trichobilharzia sp(p). Trematode infection levels increased as snail size increased. The implication for surveillance techniques is that only the larger snails (A. lessoni > 10 mm, G. gilberti > 3 mm and Amerianna carinata >6 mm) require dissection to determine the prevalence of trematode infections.
