摘要 目的比较微量凝集试验(MAT)与酶联免疫吸附试验(ELISA)检测血清中嗜肺型军团菌(Legionella pneumophila,Lp)抗体的优缺点。方法用MAT法和ELISA法检测400份南京地区公共场所从业人员的血清标本中嗜肺军团菌抗体,采用描述流行病学方法进行分析。结果 MAT法检出阳性标本51份,阳性率为12.75%,ELISA法共检出阳性标本47份,总阳性率为11.75%,差异无统计学意义(χ2=0.186,P>0.05),结果高度一致(k=0.930,u=32.75)。ELISA法检出LpIgM阳性标本28份,阳性率为7.00%,与MAT法检测结果差异有统计学意义(χ2=7.430,P<0.05);ELISA法检出Lp-IgG阳性42份,阳性率为10.50%,与MAT法检测结果差异无统计学意义(χ2=0.986,P>0.05);ELISA法检出Lp-IgM和LpIgG阳性率差异无统计学意义(χ2=3.188,P>0.05)。结论 ELISA法快速、操作简便,与MAT法检测嗜肺军团菌抗体结果高度一致,可应用于大批量标本检测。
