Abstract：
A systematic review and meta-analysis were conducted to idetnify the relative contributions of the sources of Campylobacter in poultry live production to Campylobacter prevalence of broiler meat. The keywords of Campylobacter, prevalence, live production, and broiler were used in Google Scholar to address the research interest. A total of 16,800 citations were identified, and 63 relevant citations were included in the meta-analysis after applying predetermined inclusion and exclusion criteria. A generalized linear mixed model approach combined with logit transformation was used in the current meta-analysis to stabilize the variance. The analysis revealed that Campylobacter is ubiquitous in the poultry house exterior environment including surroundings, wildlife, domestic animals, and farm vehicle, with a predicted prevalence of 14%. The recovery of Campylobacter in the interior environment of the poultry house is far less abundant than in the exterior, with a prevalence of 2%, including litter, water, insects, mice, feed, and air. A lack of evidence was observed for vertical transmission due to the day-old chicks being free of Campylobacter from 4 studies identified. Live birds are the predominant carrier of Campylobacter, with a predicted prevalence of 41%. Transportation equipment used for live haul had an overall prevalence of 39%, with vehicles showing a predicted prevalence of 44% and crates with a predicted prevalence of 22%. The results of this meta-analysis highlight the need to implement effective biosecurity measures to minimize the risk of Campylobacter in poultry meat, as human activity appears to be the primary factor for Campylobacter introduction.
摘要：
进行了系统评价和荟萃分析，以明确家禽活生产中弯曲杆菌来源对肉鸡肉弯曲杆菌流行率的相对贡献。弯曲杆菌的关键词，患病率,现场生产，和肉鸡在谷歌学者中被用来解决研究兴趣。总共确定了16,800条引文，在应用预定的纳入和排除标准后,将63篇相关引文纳入荟萃分析.在当前的荟萃分析中使用了一种结合Logit变换的广义线性混合模型方法来稳定方差。分析显示，弯曲杆菌在禽舍外部环境包括周围环境中普遍存在，野生动物,家畜,和农用车辆，预测患病率为14%。在禽舍内部环境中的弯曲杆菌的回收率远没有在外部丰富，患病率为2%，包括垃圾,水,昆虫,老鼠,饲料，和空气。从4项确定的研究中，由于一天大的雏鸡没有弯曲杆菌，因此缺乏垂直传播的证据。活的鸟类是弯曲杆菌的主要携带者，预测患病率为41%。用于现场运输的运输设备的总体患病率为39％，车辆的预测患病率为44％，板条箱的预测患病率为22％。这项荟萃分析的结果强调了需要实施有效的生物安全措施，以最大程度地降低禽肉中弯曲杆菌的风险，因为人类活动似乎是弯曲杆菌引入的主要因素。
