Abstract

We describe the occurrence of the trematode Renicola sp. associated with kidney lesions in a Cabot’s Tern Thalasseus acuflavidus from Brazil. During necropsy, we observed renal paleness, subpleural hemorrhage at the edges of the organ, and severe dilation of both ureters. Histological analysis revealed distension of the branches of the ureters, with partial obstruction due to the presence of the parasites and compression of adjacent tubules. The infection did not likely cause the tern's death.
