The sheep industry, a very important economic activity in Paraná State, can be affected by gastrointestinal parasites. The aim of the present study was to evaluate the occurrence of gastrointestinal parasites in sheep raised in the north region of Paraná State. Fecal samples were collected from 69 animals and processed by flotation and sedimentation techniques. Parasites were observed in 63 (91.3%) animals. The most frequent parasites were strongylid eggs (81.2%), followed by Eimeria sp (42%) and Giardia duodenalis (10.1%). To our knowledge, this is the first report of Giardia duodenalis in sheep raised in Parana State. These results indicate that sanitary management must be improved in order to control infections by these parasites and increase the productivity.
