Individual animal and herd seroprevalence for Mycobacterium avium subspecies paratuberculosis (MAP) and Neospora caninum (NC) among adult cattle (2nd calf and older cows, 3-year and older bulls) in beef cow-calf herds in Alberta
| Serologic assay | Individual (seropositive) % (95% CI) | Herd (≥ 1 seropositive) % (95% CI) | Herda (≥ 2 seropositive) % (95% CI) |
|---|---|---|---|
| MAP (n = 2996 animals in 100 herds) | 1.5 (0.9–2.5) | 28.5 (17.3–43.0) | 7.9 (2.3–23.4) |
| NC (n = 2996 animals in 100 herds) | 9.7 (7.6–12.3) | 91.0 (85.4–94.6) | — |

Herd positivity based on ≥ 2 seropositive animals applies only to the MAP-tested animals and herds
