| bayesian kriging of seroprevalence to mycobacterium avium subspecies paratuberculosis and neospora caninum in alberta beef and dairy cattle. | identifying spatial patterns of risk is important in the study of diseases with ecologic causes. furthermore, relatively complex hierarchical modeling is required to determine how factors that are organized across levels interact, such as how an ecologic cause interacts with farm management and with animal characteristics. the objective of this study was to map the risk for mycobacterium avium subspecies paratuberculosis (map - the causative agent of johne's disease) and neospora caninum (nc - t ... | 2007 | 18189052 |
| seroprevalence of neospora caninum in beef cattle in northern alberta. | blood samples were collected from 1806 pregnancy-tested cows from 174 herds at a northern alberta auction mart in the fall of 1998. one hundred sixty-two (9.0%) of these samples were positive for antibodies to n. caninum. thirty-five of 260 samples (13.5%) collected from the same region in the 1980s were also serologically positive for n. caninum. | 2001 | 11272457 |
