摘　　要：【目的】了解广西猪群中猪流感(SI)的流行情况,为科学防控广西SI提供参考依据。【方法】以猪流感病毒(SIV)H1N2亚型毒株为抗原,采用微量血凝抑制试验(HI)方法,对2009年7月～2011年3月在广西12个市采集的997份猪血清进行SIV的血清学调查。【结果】2009年的H1N2亚型抗体阳性率为33.4%,比2010年和2011年1～3月的高;广西各市的H1N2亚型抗体阳性率为0～83.1%,其中河池和百色两市的H1N2亚型抗体阳性率较高,分别为83.1%和51.1%,崇左市为零,其他市的H1N2亚型抗体阳性为4.0%～32.1%。【结论】广西地区猪群在2009～2011年均受到猪源H1N2亚型不同程度的感染。[ Objective ]The present study was conducted to investigate the prevalent state of swine influenza in Guangxi in order to provide reference for developing its control measures. [Method ]About one thousand swine blood samples were collected from twelve cities of Guangxi from July, 2009 to March, 2011, and were investigated serologically using trace hemagglutination inhibition （HI） test. H1N2 subtype strain of swine influenza was used as antigen. [Result]The antibodies against the subtype H 1 N2 were found higher in 2009 （positive rate 33.4% ） compared to 2010 and 2011. The positive rate in all cities of Guangxi ranged from 0 to 83.1%. The antibody positive rate of H1N2 subtype in Baise and Hechi cities was 51.1 and 83.1%, respectively, and that of the other cities ranged from 4.0-32.1%, except in Chongzuo where it was zero （0）. [Conclusion]The results demonstrated that swinery in various regions of Guangxi were infected in different degrees with H1N2 subtype of SIV at different times.
