---

The present study describes lesions caused by Kudoa sp. in the esophageal tissue of mapará catfishes(Hypophthalmus marginatus) collected from Cametá, Tocantins River in the northern Brazil. Fifty refriger-ated H. marginatus specimens were dissected and tissue samples were for embedded in paraffin andstained with hematoxylin-eosi, Masson’s trichrome and Giemsa. Pseudocysts of whitish color wereobserved in the esophagus region. The parasites had four valves and other morphological characteristicsof the genus Kudoa. Microscopic analysis revealed lesions in the mucosa, submucosa, and muscular layers.The Masson staining highlighted the presence of myxosporean cysts in the cytoplasm of the muscularfibers, and marked fibrosis of the muscular and mucous layers. The macro and microscopic findings ofthe present study confirm the presence of necrotic esophagitis in H. marginatus associated with infectionby Kudoa
