Abstract

To better understand the epizootiology of caprine paratuberculosis in the North of Portugal, a cross-sectional study was conducted from 2014 to 2015. The seroprevalence and risk factors for Mycobacterium avium subsp. paratuberculosis (Map) seropositivity were evaluated. Antibodies against Map were determined by a commercial ELISA. In 936 sera tested from 56 goat herds, 120 (12.8%, 95% CI: 10.8-15.1%) goats and 34 (60.7%, 95% CI: 47.6-72.4%) herds were positive. Risk factors for seropositivity were investigated by logistic regression models. The odds of Map seropositivity were found to be higher for animals with clinical signs, OR = 5.1 (95% CI: 2.7-9.6%), animals belonging to herds with previous wasting disease, OR = 2.3 (95% CI: 1.1-4.8%), and accumulation of manure in the herd, OR = 3.1 (95% CI: 1.7-5.7%). The potential risk factors identified in this study support the current recommendations for the control of paratuberculosis in these and other animals.

葡萄牙北部山羊副结核分枝杆菌感染血清调查。
为了更好地了解葡萄牙北部地区山羊副结核病的流行病学,2014 年至 2015 年期间进行了一项横断面研究。研究评估了副结核分枝杆菌(Map)血清阳性的血清流行率和风险因素。通过商用酶联免疫吸附法测定 Map 抗体。在 56 个山羊群检测的 936 份血清中,120 只(12.8%,95% CI:10.8-15.1%)山羊和 34 个(60.7%,95% CI:47.6-72.4%)羊群的血清呈阳性。通过逻辑回归模型研究了血清阳性的风险因素。结果发现,有临床症状的动物(OR = 5.1 (95% CI: 2.7-9.6%))、曾患过消瘦病的畜群(OR = 2.3 (95% CI: 1.1-4.8%))和畜群中粪便堆积的动物(OR = 3.1 (95% CI: 1.7-5.7%))出现马普血清阳性的几率更高。本研究发现的潜在风险因素支持目前对这些动物和其他动物副结核病的控制建议。
