BARBOSA DA SILVA, Jenevaldo et al. Detection of a high prevalence of antibodies against Toxoplasma gondii in cattle in Northern and Midwestern Brazil. Rev Salud Anim. [online]. 2015, vol.37, n.1, pp. 52-56. ISSN 2224-4700.

The aim of this study was to determine the prevalence of Toxoplasma gondii in cattle from the Northern and Midwestern regions of Brazil. Serum samples were collected from 1789 animals and tested by indirect enzyme-linked immunosorbent assay (ELISA). The overall prevalence of T. gondii was 83.40% (1492/1789). The prevalence rates of T. gondii-seropositive animals observed in the states of Pará, Tocantins and, Mato Grosso were 87.45%, 87.79% and 73.06%, respectively. The detection of high prevalence rates of T. gondii in cattle deserves special attention because they are the main source of high biological value protein for humans. This finding indicates the need for further studies on the risk that these animals may pose to public health.
