infection is prevalent in humans and animals worldwide. In the present study, a total of 612 serum samples were examined using indirect hemagglutination test (IHAT) for infection. Antibodies to were detected in 49 (8.0%, confidence interval [95% CI]: 5.9-10.2) serum samples (IHA titer ≥1:16). The seroprevalence ranged from 4.4% (95% CI: 0-10.5) to 14.3% (95% CI: 0-40.2) among different regions in Hunan province of subtropical China. The highest seroprevalence was found in breeding sows (18.8%). The seroprevalence was higher in winter (18.3%, 95% CI: 8.5-28.1) and spring (10.9%, 95% CI: 5.7-16.1) than in summer (6.4%, 95% CI: 2.8-10.1) and autumn (4.9%, 95% CI: 2.2-7.7), and the differences were statistically significant excepting summer. In addition, developmental stage and season were identified as risk factors for infection. Our findings revealed the seroprevalence of in growth stages of pigs in the Hunan province of subtropical China, indicating that it may cause public health and economic problems. To our knowledge, this is the first report of the comprehensive survey of seroprevalence in pigs in the Hunan province of subtropical China.
感染在全球范围内的人类和动物中普遍存在。在本研究中，使用间接血凝试验（IHAT）检测了总共 612 份血清样本，以检查 感染情况。在 49 份（8.0%，置信区间[95%CI]：5.9-10.2）血清样本中检测到针对 的抗体（IHA 滴度≥1：16）。在中国亚热带湖南不同地区， 的血清流行率范围为 4.4%（95%CI：0-10.5）至 14.3%（95%CI：0-40.2）。最高的血清流行率出现在繁殖母猪中（18.8%）。冬季（18.3%，95%CI：8.5-28.1）和春季（10.9%，95%CI：5.7-16.1）的 血清流行率高于夏季（6.4%，95%CI：2.8-10.1）和秋季（4.9%，95%CI：2.2-7.7），除夏季外，差异均有统计学意义。此外，发育阶段和季节被确定为 感染的危险因素。我们的研究结果显示了中国亚热带湖南地区猪生长阶段 的血清流行率，表明它可能会引起公共卫生和经济问题。据我们所知，这是中国亚热带湖南地区猪 的血清流行率的首次全面调查报道。
