Neospora caninum can cause damage so great that it is believed that reproductive diseases caused by this parasite may have outweighed the damage caused by other diseases such as brucellosis and leptospirosis. Neospora caninum is an obligate intracellular protozoan. Domestic dogs (Canis lupus familiaris), gray wolf (Canis lupus lupus), coyotes (Canis latrans), and dingo (Canis lupus dingo) are definitive hosts of the parasite. The prevalence can vary widely, depending on the type of sampling, the laboratory techniques used, which are varied and the cut-off point chosen. It has been diagnosed in several species that end up being intermediate hosts such as, asininos, equines, cervids, cats, chickens, buffaloes, cattle, goats and sheep. Table 1 shows a survey of the last 5 years of seroprevalence in cattle, sheep and goats and dogs. Neosporosis has been causing damage that is sometimes under-calculated and thus causes immeasurable damage to producers. It is observed that dogs are not the great villains in the properties, knowing that wild animals can also be definitive hosts of the protozoan and the vertical transmission also becomes very important leading to increase the number of seropositive animals of the herd.
