【摘要】：为了解近年来我国猪群中流感病毒的感染与流行情况,本研究分别对2013年11~12月期间采集于福建等9个重点养猪省份的2 198份以及2014年3~4月期间采自于广东和湖南两省的3 654份猪血清样品进行了血凝抑制(HI)抗体的检测。选取欧亚类禽型猪H1N1(EA H1N1)、2009甲型H1N1(2009/H1N1)、H3N2亚型猪流感病毒(SIV)、H5N1禽流感病毒(AIV)、H9N2 AIV及H7N9流感病毒制备的HI标准抗原作为检测抗原。结果显示,2013年我国猪群中EA H1N1、2009/H1N1、H3N2 SIV、H5N1 AIV、H9N2 AIV及H7N9流感病毒平均抗体阳性率分别为49.73%、11.87%、1.71%、0、0、1.36%;2014年分别为48.52%、12.10%、1.04%、0、0、2.05%。检测结果表明2013年~2014年间我国猪群中H1N1亚型SIV感染比较普遍,H3N2、H9N2流感病毒抗体阳性率较低,未检测到H5N1、H7N9流感病毒抗体。
[Abstract]:In order to understand the infection and prevalence of influenza virus in swine herd in China in recent years, From November to December 2013, 2 198 pig serum samples collected from 9 key pig breeding provinces including Fujian and 3 654 pig serum samples collected from Guangdong and Hunan provinces from March to April 2014 were tested for HI antibody. The HI standard antigens of H1N1(EA H9N2 AIV and H7N9 influenza virus of 2009 / 2009 H3N2 subtype swine influenza virus (H3N2) of Eurasian avian pigs were selected as detection antigens. The results showed that the average antibody positive rates of EA H1 N 1 / 2009 H 1 N 1 / H 3N 2 SIVP H5N1 AIVN 2 AIV and H7N9 influenza virus in 2013 were 49.73 and 11.87 1.71 respectively, and in 2014 were 48.5212.101.04 and 1.044.05, respectively. The results showed that the positive rate of H3N2H9N2 influenza virus antibody was lower than that of H1N1 subtype SIV infection in Chinese pigs from 2013 to 2014, and no H5N1 H7N9 influenza virus antibody was detected.
