摘要
目的了解2011-2012年广州市禽类经营环境中的职业人群H5及H9亚型禽流感的感染情况,为防治人禽流感提供科学的依据。方法采集广州市12个区从事饲养、销售和屠宰家禽的职业人群的静脉血572份,一般人群血清648份,通过血凝抑制实验进行抗体检测,采集禽类经营外环境标本415份,通过PCR进行核酸检测。结果职业人群中H5N1抗体阳性率为0.52%,一般人群H5N1抗体均为阴性,职业外环境中H5亚型标本阳性率4.10%;H9亚型阳性率1.69%。结论广州市禽类经营环境职业人群存在一定的隐性感染,职业环境中存在H5、H9亚型禽流感病毒的污染,具有感染高致病性禽流感的风险,应加强职业人群的禽流感监测,防止销售病死禽及提供充足个人防护用品,加强健康教育。
Objective To investigate the infection status of H5 and H9 influenza viruses among occupational pop- ulation in poultry environment in Guangzhou from 2011 to 2012, so as to provide scientific basis for the disease control and prevention. Methods 572 serum samples from occupational population （work for the feed, sale and slaughter of poultry）, and 648 serum samples from general population in 12 districts of Guangzhou City were detected with antibodies by hemagglutination inhibition test. Meanwhile, 415 samples collected from the poultry environment were tested with nucleic acid by using PCR technology. Results The antibody positive rate for HSN1 was 0. 52%. In the general population, the antibody of H5N1 were all negative. The positive rate for H5 was 4. 10% in the poultry environments, while it was 1.69% for H9. Conclusions There were la- tent infections of H5 avian influenza virus in occupational population. H5 and H9 avian influenza virus had contaminated the poultry environments, which existed risk of infecting highly pathogenic avian influenza. It in- dicates that the surveillance in occupational population, well management of ill poultry, enough personal pro- tective device and health education are very important for the prevention of the epidemic of avian influenza.
