玉龙县鼠疫疫源地高危人群鼠疫菌F1抗体水平调查

Investigation on F1 antibody level of Yersinia pestis among high risk populations in plague foci of Yulong County

目的了解玉龙县鼠疫疫源地高危人群中的鼠疫菌F1抗体水平及隐性感染情况。方法对疫区高危人群进行随机采集血液样本100份,应用间接血凝试验、胶体金标试验和酶联免疫吸附试验三种方法分别进行鼠疫菌特异性F1抗体检测。结果三种方法检测鼠疫菌F1抗体均为阴性。结论玉龙县鼠疫疫源地高危人群中未发现鼠疫菌隐性感染的现象,但该疫区高危人群的鼠疫抗体监测仍需继续开展。

Objective To investigate the F1 antibody level of Yersinia pestis and hidden infections situation among high risk populations in plague foci of Yulong County.Methods One hundred blood samples were randomly collected from high-risk population in epidemic area.Indirect hemagglutination assay,colloidal gold labeling test and enzyme-linked immunosorbent assay(ELISA)were used to detect the specific F1 antibody of Yersinia pestis.Results The F1 antibody of Yersinia pestis were tested to be negative with three methods.Conclusion No hidden infections situation of Yersinia pestis is found in the high-risk population in Yulong County,while the monitoring of the plague antibody in high-risk population of Yulong County remain to continue.
