摘要:

目的 检测宿主动物血清中鼠疫菌素(Pesticin,Pst)抗体,探究Pst作为鼠疫抗体检测诊断试剂的可能性。方法 采用重组Pst和鼠疫F1抗体间接ELISA法,对351份不同来源的鼠疫宿主动物血清样本进行检测。结果 在鼠疫感染的宿主动物体内可以检测到Pst抗体,Pst抗体水平随着F1抗体水平的升高而明显升高,鼠疫患者血清中20个月时ELISA检测A值为0.438,Pst抗体维持在可检出水平。结论 Pst抗体检测方法可以与传统鼠疫F1 抗体检测相结合,使鼠疫抗体检测方法更具可靠性。

Abstract:

Objective To detect pesticin (Pst) antibody in the sera of plague host animals and to investigate the feasibility of using Pst as the diagnostic reagent in plague antibody detection. Methods A total of 351 serum samples of plague host animals from different sources were subjected to indirect enzyme?linked immunosorbent assay (ELISA) for detection of recombinant Pst antibody and F1 antibody. Results Pst antibody was found in the serum samples of plague host animals, and the serum level of Pst antibody increased significantly as the serum level of F1 antibody rose. The ELISA absorbance value was 0.438 in plague patients 20 months later, and the Pst antibody in serum remained at a detectable level. Conclusion Pst antibody detection can be used along with F1 antibody detection, so as to make plague antibody detection more reliable.
