“…The pancreas were macroscopically analyzed and images were collected to confirm the parasite contamination. The collected parasites were fixed in Railliet and Henry's solution (930 mL of distilled water, 6 g of sodium chloride, 50 mL of formalin and 20 mL of glacial acetic acid) (Fernandez et al, 2006). Subsequently, the trematodes were cleared with 80% acetic acid for the species' microscopic confirmation.…”

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.

introduction:The Baixada Maranhense Microregion currently has the highest prevalence of schistosomiasis in the State of Maranhão, likely because this parasitosis is characterized as an occupational disease, and increased contact with water increases the risk of infection by Schistosoma mansoni. This paper reports the results of the fi rst comprehensive freshwater malacological survey performed in the Baixada Maranhense Microregion. Methods: Freshwater mollusks were collected from the twenty-one municipalities of the Baixada Maranhense Microregion and from Bacurituba and Cajapió and were evaluated for infection by trematodes. Results: A total of 9,129 mollusks were collected (sixteen species), which included the fi rst records of six species in the State of Maranhão: Gundlachia radiata, G. ticaga, Hebetancylus moricandi, Plesiophysa guadeloupensis, Pomacea bridgesii diffusa and Omalonyx sp. Biomphalaria glabrata was found in fi ve municipalities, whereas B. straminea was found in nine. Biomphalaria glabrata and B. straminea were observed in syntopy in Pinheiro and São Bento. Of the 990 specimens of B. glabrata and the 2,109 specimens of B. straminea that were exposed to and/or analyzed for the presence of larval trematodes, only a single specimen of B. glabrata (0.1%) from São Bento shed S. mansoni . Other larval trematodes were fi rst observed in mollusks from the State of Maranhão. Conclusions: These results indicate that the study area is epidemiologically important due to the presence of two natural vectors of schistosomiasis and the active transmission of schistosomiasis, which was confi rmed in the infected specimen that was collected in this study.
