【摘要】 目的　了解某军校学员诺瓦克样病毒抗体水平 ,同时调查分析与血型、入学前家庭所在地等的关系。方法　利用酶联免疫吸附试验检测血清中的诺瓦克样病毒rNV、rMX和r387特异性IgG抗体水平。结果　rNV、rMX和r387IgG抗体总检出率分别为 88 9% ,5 4 1%和 90 0 %。其中rMX抗体阳性率不同血型之间存在显著性差异 (P<0 0 5 ) ,以O型抗体阳性率最高 6 2 5 % (115 / 184 ) ,B型最低 4 9 1% (16 0 / 2 16 ) ,而rNV和r387抗体阳性率未见显著性差异。不同入学前家庭所在地 3种抗体阳性率均有显著性差异 ,其中以农村籍学员抗体阳性率最高 ,城市最低。结论　该军校人群中诺瓦克样病毒感染普遍 ,血型及入学前家庭所在地可能是影响诺瓦克样病毒抗体水平的因素更多还原

【Abstract】 Objective To investigate serum antibodies against Norwalk-like viruses of a military university and the concerned factors ;such as blood type and the family locus before enrolling.Methods Serum specimens are tested by an indirect enzyme-linked immunosorbent assay(ELISA) for specific IgG respectively to rNV,rMX and r387.Results The seroprevalence is 88.9% for rNV,54.1% for rMX and 90.0% for r387.There is significant difference between blood types for rMX of which the type O prevalence is the highest(62.5%),and the type B is the lowest(49.1%).And there is significant difference between the family locus before enrolling for rNV,rMX and r387.Conclusion The data indicates that infections of Norwalk-like viruses in the military university are very common.And blood type and family locus before enrolling may be the risk factors of the serum antibodies of Norwalk-like viruses.更多还原
