Results Several amino acid substitutions located in antigenic sites or receptor binding sites were found more in the isolates than the current vaccine virus or the isolates from previous year. Amino acid substitution was found in 3, 140, 142, 144, 145, 158, 159, 189, 192, 193, 198, 204, 225, 226 and 227 positions in the isolates during 2003-2008, more amino acid substitutions took place in antigenic determinant A, B and receptor binding site.

结果 每个流行期分离的毒株都较当年的疫苗株或前一年的毒株出现了位于不同抗原决定簇或者受体结合位点的氨基酸替换。2003-2008年不同流行期分离株在3，140、142、144、145、158、159、189、192、193、198、204，225、226和227位点氨基酸发生了变化，多数的改变发生在抗原决定簇A、B及RBS。

The sensitivity and specificity of catalase was 25% and 100%, and of HAP2 was 90.6% and 60%. The results showed that the antigenicity of HAP2 is sensitive in detecting false negative sera group and may be applied to serodiagnosis in combination with other immunodominant antigens.

其中catalase的灵敏度和准确度为25％和100％，而HAP2则为90.6％及60％，显示HAP2具有较佳的抗原性，并对伪阴性血清样本有很高的灵敏度，未来可与其他高抗原性蛋白组合应用於幽门螺旋杆菌感染的检测。
