RESUMO:

Wild boars represent a potential source of dissemination of pathogens of importance to public and animal health, since they can be reservoirs of several pathogens. The objective of this study was to evaluate the health profile of wild boars hunted for population control in the state of Santa Catarina, located in southern Brazil. For this study, 61 wild boar tissue and blood samples were collected of hunted for population control from October 2017 to November 2018. The 61 blood serum samples were screened for antibodies by different assays, yielding the following seroprevalence: porcine circovirus type 2 (52%), Mycoplasma hyopneumoniae (20%), Influenza A virus (10%), Leptospira spp. (21%) and Hepatitis E virus (14%). For Brucella spp. and classical swine fever were not seroreactive. At necropsy, the main lesions observed were evidence of pulmonary parasites (metastrongylides), hemorrhagic lymph nodes and white-spotted liver. Histopathological analyzes showed mainly interstitial pneumonia, bronchopneumonia and BALT hyperplasia. There was a significant association between metastrongylid pulmonary parasitism and BALT hyperplasia. Pathological findings of wild boars indicate that the individuals assessed were not exposed to notifiable pathogens / diseases, which cause economic damage by non-tariff trade barriers such as classical swine fever, african swine fever and foot-and-mouth disease. However, the detection of antibodies against PCV2 and Mhyo, pathogens that impact commercial production, indicates the circulation of these agents, varying in frequency in wild populations, which characterizes the potential risk of disease/pathogen transmission among domestic swine populations and free-living in both directions. The detection of antibodies against zoonotic agents such as hepatitis E virus, Influenza A virus and Leptospira spp., besides characterizing the circulation of the agents in these populations, suggest a potential risk to public health and/or pig farming, depending on the interactions they establish with the environment, humans and domestic pigs. With the results of this work, it is recommended to increase the biosecurity of commercial farms, as well as care in the handling of carcasses of these animals and the deepening of studies of the health profile of wild boars in Santa Catarina state and in Brazil and its implications for the environment, livestock and public health.
