摘要: Neosporosis is an emergent disease responsible for considerable economic impact due to reproductive losses. Its zoonotic potential remains unknown. This study involved a survey of antibodies Neospora caninum in slaughtered sheep and their association with epidemiological variables. Serum samples from 596 the states Sao Paulo Rio Grande do Sul, Brazil, were collected two slaughterhouses located evaluated by indirect fluorescence antibody test (IFAT), using cut-off titers 25. Among these samples, 353/596 (59.23%; 95%CI 55.23-63.10) positive 263/353 (74.50%; 69.71-78.77%) Sul. Statistical associations determined univariate analysis between serological results sex, breed municipality origin. Sheep that came extensive breeding system showed higher chance (OR=2.09) presenting N. relation those semi-intensive system. Higher was also observed different studied breeds, except Bergamacia, Hampshire Down. The revealed presence infection slaughterhouses.
