The aim of this study was to determine seroprevalence of Neospora caninum in dairy cattle ranches with higher abortion rates and co-existence of Neospora caninum, Toxoplasma gondii, Brucella abortus, and Listeria monocytogenes antibodies. The blood samples were collected from dairy cows with history of abortion (n = 234) as well as from pregnant cows that were (n = 323) kept in the same ranches. N. caninum seroprevalence was 10.77% (60/557). The co-existence rate of N. caninum seropositivity with T. gondii, B. abortus and L. monocytagenes was 24.77% (138/557), 13.82% (77/557) and 42.85% (162/378), respectively. Only one animal had significant antibody titers for all analyzed infectious agents. The seroprevalence of N. caninum and T. gondii were significantly higher in pregnant cows than aborted cows (p < 0.05 and p < 0.001, respectively). As a result, the comprehensive data generated through this study can significantly contribute to understanding of serologic association of N. caninum with T gondii, B. abortus and L monocytogenes in pregnant and aborted dairy cows.
