山西省2000年不同地区人群流行性感冒抗体水平检测

Survey of Influenza Virus Antibodies in Healthy Population in Different Districts of Shanxi Province in 2000

为了解流行性感冒 (流感 )病毒抗体在不同的人群、地区及时间的分布情况 ,用血凝抑制试验测定了太原、长治、昔阳 3个地区不同年龄组的 5 36份健康人群血清标本。经过 1999年的流行期 ,山西省 2 0 0 0年健康人群中甲1型、甲3 型及乙型流感抗体阳性率分别达到了 77 80 %、80 78%和 76 4 9%。经t检验 ,不同地区间和各年龄组间甲1型及甲3 型流感抗体滴度有所不同 ,长治明显高于太原、昔阳。乙型流感抗体滴度除太原较低外 ,其它两地间差异无显著的统计学意义。人“O”型血球用于测定流感抗体与其它血球相比 ,具有易采集。

In order to understand th e distribution of influenza virus antibodies in different districts and different people,we tested the antibody titers of 536 healthy per sons in three districts (Taiyuan,Ch angzhi,Xiyang) by using hemagglutin ation inhibition(HAI)test The posi tive rates of A1、A3 and B antibodi es were 77 81%,80 78% and 76 49% r espectively among the population t ested in 2000 By t test,influenza A1,A3 antibody titers were higher in Changzhi than that in Daiyuan a nd Xiyang,the titer of influenza B was lower in Taiyuan but had no si gnificant statistical difference in Changzhi and Xiyang.The human“O”ty pe blood cell is more convenient to collect than blood of chicken,guinea pig and turkey and it has no non-s pecific agglutination reaction wit h human serum But there is differe nt sensitivity to HA from different p erson’s“O”blood cell,it should be tested ahead of time
