Neospora caninum and Leptospira serovar serostatus in dairy cattle in Ontario.
No significant association existed between Neospora caninum titer and serostatus to Leptospira serovar hardjo, icterohaemorrhagiae, or pomona in cattle on 78 dairy herds in Ontario. Leptospira titer increased with parity. Amongst herds not vaccinated against Leptospira, the proportions of herds with > or = 1 animal seropositive to serovar hardjo, icterohaemorrhagiae, or pomona were 45%, 42%, and 58%, respectively.
