For this reason, the international organization Wildlife Conservation Society (WSC) has been concerned with this species and has developed population monitoring and control programs, however, they currently do not have the advice of a veterinarian who determines that Turtles in protection are healthy before release. This aspect influenced the need to verify the health status of protected animals, so the objective of this study was to perform a histopathological analysis of a population of thirty individuals of charapa turtles (Podonecmis unifilis) belonging to 3 communities (Sani Isla, Nueva Providencia and Indillama) that are part of the WCS conservation program, to determine the health status of the animals prior to their release. The investigation was carried out using 10 randomly chosen neonatal individuals within each community who were sacrificed and subjected to necropsy, from these animals samples of liver, gallbladder, pancreas and spleen were collected, fixed, stored in 10 percent buffered formalin, processed to obtain histological sheets, and analyzed by light microscopy. Histopathological analysis determined lesions in 2 organs, the liver being the most affected, where a congestive process was observed mainly in the area adjacent to the centrolobular vein and the portal triad in 36 percent of the samples analyzed, a process of lipidosis in 18, and focal fibrotic lesions were also highlighted near the capsule, in the portal vein and in the lobular area in 15 percent. The Sani Isla community presented a greater number of lesions associated with hepatic lipidosis. The pancreas showed congestive areas in the acinar zone by 10 percent. In conclusion, it was determined that the organs analyzed have slight alterations or histopathological findings mainly in the liver and pancreas, lesions related to physiological processes associated with the nutrition and euthanasia of the animals, and there are no infectious processes determining that the organs of the animals analyzed are apparently healthy. |
