EnglishWild boars (Sus scrofa) have become an important invasive species in all Brazilian regions. Increase in their population causes damage to rural properties, as they invade and destroy crops. To protect their crops and farm animals, producers hunt wild boars and often consume the product without any sanitary control, becoming exposed to various types of pathogens, including Toxoplasma gondii. Sanitary evaluations of these animals are scarce, especially in relation to the protozoan T. gondii. This study aimed to evaluate the occurrence of this pathogen in wild boars in Brazil. We analyzed 122 blood samples from wild boars (blood clots and serum), collected between 2014 and 2016 in five Brazilian states, using polymerase chain reaction (PCR) and indirect hemagglutination (IH) techniques. In total, 33 (27%) samples were positive by at least one test, 16 (13.1%) were positive by PCR, 19 (15.6%) were positive by IH, and only 2 (1.6%) were positive by both tests. The lack of sanitary management of feral animals increases the incidence of infections, and the consumption of raw or inadequately cooked meat may become a potential source of infection for humans in Brazil.

Com o aumento de sua populacao causam danos em propriedades rurais, invadindo e destruindo lavouras. Como alternativa para proteger suas culturas e criacoes, os produtores os cacam e muitas vezes consomem o produto sem qualquer tipo de controle sanitario, expondo esses consumidores a diversos tipos de patogenos, entre eles o Toxoplasma gondii. Avaliacoes sanitarias destes animais sao escassas, principalmente, em relacao ao protozoario T. gondii. Este trabalho teve como objetivo avaliar a ocorrencia deste patogeno em javalis de vida livre no Brasil. Foram analisadas 122 amostras de sangue de javalis (coagulos sanguineos e soro), coletadas entre os anos de 2014 a 2016, de cinco estados do Brasil, atraves da tecnica da Reacao em Cadeia da Polimerase (PCR) e da tecnica de hemaglutinacao indireta (HI). No total, 33 (27%) amostras foram positivas em pelo menos um teste, sendo 16 (13,1%) na PCR e 19 (15,6%) na IH e apenas 2 (1,6%) em ambos os testes. A falta de manejo sanitario dos animais ferais aumenta a incidencia de possiveis infeccoes e o consumo da carne crua ou sem coccao adequada pode vir a ser potencial fonte de infeccao para humanos.
