Aspects and Applications of Epidemiological Chain of Bovine Neosporosis as Prophylaxis Tool on Rural Properties

Bovine Neosporosis (NB) directly interferes with the reproductive indices of bovine farming, being the main cause of abortions in bovine herds not only in Brazil, but also throughout the world.Given the importance of this disease for animal health, the present work points to the need for a reflection about the knowledge of the epidemiological chain of NB as a prophylactic tool in rural properties.The objectives of this work were to describe and point out the importance of knowledge about the biology and epidemiology of Neospora caninum, in order to subsidize effective measures of prophylaxis in rural properties.In the face of the analysis, it was possible to observe that in addition to the reproductive impacts, NB can cause abnormalities and neurological disorders in newborn calves, resulting in a reduced weight gain and growth delay, which generates large financial and sanitary losses to breeders.Measures such as the use of diagnostic tests for the identification of cases, sealing the presence of dogs in the production areas in order to avoid infection through feces in contact with water or food, as well as preventing the ingestion of placental remains or dead animals in the areas of the site are effective actions of prophylaxis of NB.In addition, integrated actions of sanitary, reproductive, nutritional and environmental handling represent tools to avoid the disorders caused by NB.
