DETECTION OF ANTI- T. GONDII AND ANTI- N. CANINUM IMMUNOGLOBULINS IN CATTLE IN THE STATE OF RIO GRANDE DO SUL

Abstract

Neosporosis and toxoplasmosis are diseases of importance in the reproductive sphere and public health. Seroprevalence data for these protozoa in regions with major bovine productive chains in Brazil, such as the South, are necessary to understand the extent of the problems caused by these diseases, as well as to improve the use of prophylactic and control measures. The results of the serological survey carried out by this study, using the Indirect Immunofluorescence (IFI) reaction to detect antibodies against T. gondii and anti-N. caninum, showed positive animals for infection by T. gondii(7.2%) and N. caninum (7,6%), below those mentioned in the literature in the State of Rio Grande do Sul, which seems to have lower prevalences when compared to other regions of Brazil, characterizing moderate dissemination of these agents.
