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), respect...
