在英格兰,一项对子的控制政策在四年内显著降低了56%的牛结核病率. 这凸显了管理大种群的重要性,以控制牛结核病的传播.
科学领域:
- 兽医流行病学 兽医流行病学
- 野生动物疾病生态学 野生动物疾病生态学
- 传染病控制和控制传染病
背景情况:
- 英国牛的持续性结核病 (TB) 与与大 (Meles meles) 交换感染有关.
- 2013年实施了一项控制政策 (BCP),以减少种群和减轻对牛的结核病传播.
研究的目的:
- 估计与BCP相关的牛结核病发病率的变化.
- 确定在鸟种群干预后结核病减少的时间和规模.
主要方法:
- 分析了52个BCP干预区域 (200-1600公里2) 的监测数据.
- 差异差异分析的差异,以考虑非随机区域选择和干预开始时间.
- 估计结核病发病率变化相对于每个地区的BCP开始日期.
主要成果:
- 在BCP实施后的第四年,牛群结核病发病率减少了56% (95% CI 41-69%).
- 最显著的结核病发病率下降发生在BCP的第二年和第三年.
- 除了四年之外,进一步减少的证据是不够的.
结论:
- 减少子种群密度对于降低牛群结核病发病率至关重要.
- 这些发现提供了与鸟向干预相关的结核病下降的精确估计.
- 其他控制策略,如子疫苗接种,生育控制和农场生物安全,也可能减少结核病的传播.
