Estimated frequencies (with 95% confidence interval) of M. hyopneumoniae, A. pleuropneumoniae, P. multocida, H. parasuis and S. suis detection in breeding sows followed in five farrow-to-finish herds (184 sows, 8 sampling times, nasal, tonsillar and oro-pharyngeal swabs, PCR assays, Generalized Estimation Equations models with an autoregressive correlation matrix).
| Herd | Mycoplasma hyopneumoniae | Actinobacillus pleuropneumoniae | Pasteurella multocida | Haemophilus parasuis | Streptococcus suis |
|---|---|---|---|---|---|
| A | 0.6b (0.0;37.3) | 48.0c (34.6;61.7) | 8.4a (3.6;18.5) | 21.6b (13.6;32.3) | 45.9a (30.3;62.3) |
| B | 0.4b (0.1;2.6) | 11.6a (9.3;14.4) | 20.1c (16.2;24.6) | 19.1b (15.7;23.1) | 71.2b,c (65.7;76.1) |
| C | 4.1a (0.1;68.2) | 29.6b (19.2;42.7) | 22.5c (13.4;35.3) | 4.7a (2.2;9.6) | 76.4b (63.4;85.8) |
| D | 5.7a (0.1;75.5) | 34.2b (23.6;46.7) | 45.0b (30.9;60.0) | 50.2c (37.0;63.3) | 54.5a (39.3;68.9) |
| E | 0b (0.0;0.0) | 41.2b,c (27.7;56.3) | 26.9c (15.8;41.9) | 30.1d (19.1;44.0) | 79.1c (66.2;88.0) |
Herds with different subscripts (a, b, c and d) have a significantly different PCR-prevalence (p < 0.05, Generalized Estimation Equations model).
