RIEKEHR JUNIOR, L.E. et al. Comparative parameters of plasma biochemical indicators of two populations of Coati (Nasuanasua - LINNAEUS, 1766) with and without human action. Arq. Bras. Med. Vet. Zootec. [online]. 2017, vol.69, n.3, pp.659-666. ISSN 1678-4162.

The coatis, carnivorous mammals of the Procyonidae family, are omnivorous animals, found in North, Central and South America and are widely distributed in Brazil. The objective of this study was to analyze changes in blood parameters in two different populations of coatis (Nasua nasua), of the western region of Paraná, and to evaluate the quality of life and the human interference in eating habits of these animals. Serologic analysis was performed in two different populations of coatis (Nasua nasua) inhabiting two conservation units in different areas in the city of Foz do Iguaçu. In one population, approximately fifty individuals were visualized, revealing themselves in direct exposure to humans as well as another minor population of about thirty individuals, which have no direct exposure to humans, which revealed important indicatives of the quality of life and health of these animals. Biochemical assessments of ten adults coatis serum were perfomred, five animals in group 1, population exposed to humans and five animals of the group 2, population less exposed. With the obtained results, comparisons were made between the groups’ biochemical values and the reference values found in the literature. Biochemical tests revealed significant changes in glucose levels and total protein and changes in plasma levels of triglycerides in coatis captured in the population in direct contact with humans. It follows that the health of animals that have direct exposure to humans is being affected by the consumption of a diet high in carbohydrates and fats, coming from processed foods provided by tourists.
