Abstract: Neospora caninum is a world-wide coccidian protozoa which causes considerable damages at animals breeding. To survey the frequence of anti-N. caninum antibodies in bovine milkmen in Parauapebas county, Southeast Mesoregion of Pará State, Northern Brazil, 465 serum samples coming from 45 farmers were submitted to indirect immunofluorescence reaction (cutting point 1:100); 62 (13,33%) samples have demonstrated the presence of anti-N. caninum antibodies, with the following distribution: 27 (43,55%) in 1:100 dilution; 14 (22,58%) in 1:200 dilution; 16 (25,80%) in 1:400; and 5 (8,07%) in 1:800 dilution. None serum had tittle in over 1:800 dilution. In a high percentage there was only an animal with anti-N. caninum antibodies; the major frequence was observed between females, but was’nt observed significative difference between animal sexes; animals with equal or over five years old presented major percentage of positive serum proporcionaly to number of positives serum of younger animals. The results have demonstrated that bovine milkmen of Parauapebas county had a considerable frequence of anti-N. caninum antibodies. Sanitary surveillance measures are necessary to prevent the entrance of N. caninum and to control the difusion of this protozoa at the regional bovine milkmen.
