Enzootic pneumonia caused by Mycoplasma hyopneumoniae is a severe disease of pigs, causing significant economic losses to the pig industry worldwide, including the tropical and subtropical regions. In order to obtain the baseline prevalence of M. hyopneumoniae in pigs from intensive farms in southern China, double-sandwich enzyme-linked immunosorbent assay (ELISA) was used to detect M. hyoneumoniae antibodies in 460 pig serum samples collected from 12 administrative cities in China's southern Guangdong province. According to the proportions of the infected animals, among the 12 intensive farms, only two of them showed no infection of M. hyoneumoniae and the seroprevalence ranged from 0% to 90%, with an averaged prevalence of 45.7%. The highest prevalence was found in breeding boars (68.8%), followed by sows (54.5%). These data showed that the infection of pigs with M. hyopneumoniae is severe, and boars might be more important carriers and transfers of M. hyoneumoniae than sows. Integrated strategies and measures should be taken to control the infection of pigs with M. hyopneumoniae in southern China.
猪肺炎支原体引起的地方性肺炎是猪的一种严重疾病，给包括热带和亚热带地区在内的全球养猪业造成了重大经济损失。为了获得中国南方集约化猪场猪肺炎支原体的基线流行率，采用双夹心酶联免疫吸附测定（ELISA）法对从中国广东省南部12个行政市采集的460份猪血清样本中的猪肺炎支原体抗体进行检测。根据感染动物的比例，在12个集约化猪场中，只有两个猪场未感染猪肺炎支原体，血清阳性率为0%至90%，平均阳性率为45.7%。阳性率最高的是种公猪（68.8%），其次是母猪（54.5%）。这些数据表明，猪肺炎支原体对猪的感染情况严重，公猪可能比母猪更重要的猪肺炎支原体携带者和传播者。应采取综合策略和措施来控制中国南方猪肺炎支原体对猪的感染。
