Résumé : | The current case-control study was designed to highlight Rhodococcus equi pneumonia risk factors linked to the farm structur and husbandry practices in Basse-Normandie and to compare these results with those obtained from research in other countries. Data from 93 farms (29 endemically affected farms and 69 unaffected farms) were collected and compared by unvariate analysis then conditional logistic regression analysis. In rhodococcosis affected farms, a global analysis model evidenced 4 main risk factors (reaching or exceeding of the maximal broodmare capacity, late birth (in May and/or June), the shared use of medical (ultrasound and/or insemination) facilities by both transient and resident mares and the potential foal exposure to dust). The influence of exceeding maximal broodmare capacity may confirm the recognized impact of animal population on the possible R. equi infection. Fostering early foalings has been an usual recommendation for prevention of R. equi. The shared use of medical facilities reflects animals mixing and may be related to the contagious aspect of R. equi pneumonia. Potential foal exposition to dust, doubtless correlated to the concept of an infectious challenge by virulent R. equi in the air, seems to be the preponderant risk factor here. Further studies are needed to quantify the virulent R. equi aerosol forms in the foal environment in affected and control farms in order to propose some prophylactic efficient measures. |
