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.

Sera samples were collected from 330 water buffaloes on Marajó Island, state of Pará, Brazil, to assess the presence of antibodies against Borrelia burgdorferi by indirect Enzyme Linked Immunosorbent Assay. Approximately 45% of the animals had antibodies against B. burgdoferi. The prevalence of seropositive buffaloes, 72% (85/118), was statistically higher in the city of Soure than in the other municipalities tested. Murrah breed animals were significantly more seropositive (Prevalence Ratio (PR) = 1.84, p = 0.000) than those of the Mediterranean breed. Among the animals diagnosed positive for tuberculosis, 33% (4/12), were also seropositive for B. burgdoferi. Animals positive for tuberculosis had a significantly lower level of B. burgdorferi...
