The samples were analyzed by IFAT for the detection of anti-Neospora caninum and anti-Toxoplasma gondii IgG antibodies. Forty-five (12%) samples were seropositive to N. caninum, while 102 (26%) samples were seropositive to T. gondii. Only four animals were seropositive to both coccidia. No significant difference was observed between the N. caninum serology and any of the variables studied, such as dairy cattle management, milk production, reproductive problems, feeding, and presence of dogs, cats and rodents. These data suggest that neosporosis is present among dairy cattle in the studied geographic region and the simultaneous detection of serum positive animals to both types of coccidian parasite demonstrates the independent occurrence of these coccidia in dairy cows.
