, a kind of obligate intracellular Gram-negative bacteria, can infect humans and animals worldwide, including pigs. However, the information on infection is unavailable in pigs in Shandong province, eastern China. To assess the seroprevalence and risk factors of infection in pigs in Shandong province, eastern China, a total of 2108 serum samples of slaughter pigs were collected between January 2017 and December 2018, and specific antibodies against were detected by the indirect hemagglutination assay. The overall seroprevalence was 24.15% (509/2108, 95% confidence interval: 22.32-25.97). Species, sampling regions, and rearing systems of pigs were considered as risk factors for infection through statistical analysis by SAS analysis ( < 0.05). These results indicated that is highly prevalent in slaughter pigs in Shandong province, eastern China, and may pose a potential risk for human health. To our knowledge, this is the first investigation of seroprevalence in slaughter pigs in Shandong province, eastern China. Moreover, this is the first report to compare the seroprevalence between domestic pigs and farmed wild boars in a same study, which may provide important data for preventing and controlling infection in pigs in China.
猪霍乱弧菌，一种专性细胞内革兰氏阴性菌，可感染全世界的人类和动物，包括猪。然而，在中国东部的山东省，有关猪感染的信息尚不清楚。为评估中国东部山东省猪感染的血清流行率和风险因素，我们于 2017 年 1 月至 2018 年 12 月间采集了 2108 份屠宰猪血清样本，通过间接血凝试验检测了针对猪霍乱弧菌的特异性抗体。总的血清阳性率为 24.15%（509/2108，95%置信区间：22.32-25.97）。通过 SAS 分析进行的统计分析表明，猪的种类、采样区域和养殖系统是感染的风险因素（ < 0.05）。这些结果表明，猪霍乱弧菌在中国东部的山东省屠宰猪中高度流行，可能对人类健康构成潜在威胁。据我们所知，这是首次对山东省屠宰猪进行猪霍乱弧菌血清流行率调查。此外，这是首次在同一研究中比较家猪和养殖野猪之间的猪霍乱弧菌血清流行率，这可能为中国猪感染的预防和控制提供重要数据。
