Eurytrematosis is a helminthic disease caused by trematodes belonging to the genus Eurytrema spp. that parasitize the pancreas of many animals and humans. This parasitosis causes chronic fibrosing pancreatitis, fat infiltration in the pancreatic parenchyma, besides damaging the exocrine pancreas, which is similar to that found in patients with Diabetes Mellitus type 1 (DM1). The current work aimed to evaluate the use of bovine pancreas infected with E. coelomaticum as a model to study DM1 pathophysiology. It was carried out macroscopic analyses, parasite identification, total pancreatic lipid determination and oxidative damage biomarkers levels of pancreas naturally infected with E. coelomaticum. Macroscopically, we observed that the infected pancreas had duct obstruction, organ stiffness due to the visible presence of fibrosis, increased adipose tissue deposition, increased protein and lipid damage, as well as increased antioxidant biomarkers (GSH, CAT and VIT C). Thus, it is possible to show that DM1 may have pancreatic parasitism as a possible primary origin. However, more studies are needed to better investigate this possible primary origin; the results obtained here suggest that the use of pancreas parasitized by E. coelomaticum could be a model to investigate DM1 pathophysiology.
