Porcine enzootic pneumonia caused by Mycoplasma hyopneumoniae affects the global pig industry with significant economic losses. It is yet to know whether wild boars in China were infected with M. hyopneumoniae. The present study was conducted to examine the seroprevalence and to evaluate risk factors of M. hyopneumoniae infection in farmed wild boars in China. A total of 882 serum samples were collected from farmed wild boars in Jilin City, Siping City and Baishan City in Jilin Province, northeastern China from April 2015 to February 2016, and were examined by the double sandwich enzyme-linked immunosorbent assay (ELISA). Seventy-eight out of 882 (8.8%) serum samples were M. hyopneumoniae-seropositive. Among region groups, wild boars from Jilin city (11.7%, 33/281) had the highest seropositivity, followed by Siping city (11%, 29/263) and Baishan city (4.7%, 16/338), and the difference was statistically significant (P = 0.0031). The M. hyopneumoniae seroprevalence in the female wild boars (9.0%, 75/831) was higher than that in the male wild boars (5.9%, 3/51) (P = 0.4429). The results of this investigation showed that farmed wild boars were susceptible to M. hyopneumoniae. Logistic regression analysis showed that there is a significant correlation between the geographical area and M. hyopneumoniae infection, which may be related to the regional environment. This is the first report of M. hyopneumoniae seroprevalence in farmed wild boars in China, which provided baseline information for further studies and control of M. hyopneumoniae infection in wild boars in China.
由猪肺炎支原体引起的猪地方流行性肺炎影响着全球养猪业，造成了巨大的经济损失。目前尚不清楚中国的野猪是否感染了猪肺炎支原体。本研究旨在检测中国养殖野猪中猪肺炎支原体的血清流行率，并评估其感染的风险因素。2015年4月至2016年2月，在中国东北吉林省的吉林市、四平市和白山市的养殖野猪中，共采集了882份血清样本，并采用双夹心酶联免疫吸附试验（ELISA）进行检测。882份血清样本中，有78份（8.8%）猪肺炎支原体血清学阳性。在不同地区组中，吉林市的野猪血清阳性率最高（11.7%，33/281），其次是四平市（11%，29/263）和白山市（4.7%，16/338），差异具有统计学意义（P = 0.0031）。雌性野猪的猪肺炎支原体血清流行率（9.0%，75/831）高于雄性野猪（5.9%，3/51）（P = 0.4429）。本调查结果表明，养殖野猪易感染猪肺炎支原体。逻辑回归分析表明，地理区域与猪肺炎支原体感染之间存在显著相关性，这可能与区域环境有关。这是中国养殖野猪中猪肺炎支原体血清流行率的首次报告，为进一步研究和控制中国野猪中猪肺炎支原体感染提供了基线信息。
