Abstract

The first study examined long-term impact of a N. caninum-associated abortion outbreak in a large northern Alberta cow-calf herd.

Blood samples were collected three times from all bred females and from heifer calves born the spring before the outbreak (average age 7-9 months). These blood samples were collected (1) at the time of the outbreak, (2) the following spring, and (3) again the subsequent fall.
