%X The pathology induced in turkeys (Meleagris gallopavo) by one cestode species Hymenolepis cantaniana is described together with data on prevalence, mean infection and range of worm burdens. H. cantaniana occurred with a prevalence of 5.0 % in the 40 examined hosts in a range of 14-21 specimens and a mean intensity of 17.5. Gross lesions were not observed in the parasitized birds. Lesions due to H cantaniana mainly consisted of multiple segments of parasites, together with a mild mixed inflammatory reaction with the presence ofmononuclear cells and heterophils or severe transmural inflammatory processes, characterized by the presence ofmononuclear cells along the muscular and serosa layers of the intestinal villi and crypts. These are the first pathological findings related to the presence ofcestodes in turkeys to be reported in Brazil so far. Raillietina tetragona, not pathogenic to the present investigated turkeys, occurred with a low prevalence and range of infection of 2.5% and 1-2 worms, respectively. Duas especies de cest車ides em perus, Meleagris gallopavo (Galliformes, Phasianidae), no Brazil: patologia induzida por Hymenolepis cantaniana e ocor那ncia de Raillietina tetragona. A patologia induzida em perus pelo cest車ide H. cantaniana 谷 descrita, com dados sobre preval那ncia, intensidade media e amplitude das cargas parasitarias. H. cantaniana ocorreu com urna preval那ncia de 5.0%  as 40 aves examinadas, com intensidade media de 17.5 e amplitude de 14-21 esp谷cimes de cest車ides. N o foram observadas les es macrosc車picas nos perus parasitados. As les es provocadas por H. cantaniana eram representadas, principalmente, ou por m迆ltiplos segmentos dos par芍sitos, acompanhados por discreta rea  o inflamatoria mista com a presera de c谷lulas mononucleares e heter車filos, ou por severos processos inflamatorios transmurais, caracterizados pela presera de c谷lulas mononucleares, ao longo das carnadas muscular e serosa das vilosidades e criptas intestinais. Estes representam os primeiros achados patol車gicos relacionados a presera de cest車ides em perus a serem relatados no Brasil. Raillietina tetragona, n o patog那nica para as aves investigadas, ocorreu com baixa preval那ncia e amplitude de infec  o de 2.5% e 1-2 par芍sitos, respectivamente.
