Abstract

We investigated whether the recombinant Borrelia Western blot test previously described (B. Wilske, C. Habermann, V. Fingerle, B. Hillenbrand, S. Jauris-Heipke, G. Lehnert, I. Pradel, D. Rössler, and U. Schulte-Spechtel, Med. Microbiol. Immunol. 188:139-144, 1999) can be improved by the addition of VlsE and additional DbpA and OspC homologues. By using a panel of sera from 36 neuroborreliosis patients and 67 control patients, the diagnostic sensitivity of the recombinant immunoblot test was significantly increased (86.1% versus 52.7%) without loss of specificity and was higher (86.1% versus 63.8%) than that of the conventional whole-cell lysate immunoblot test (U. Hauser, G. Lehnert, R. Lobentanzer, and B. Wilske, J. Clin. Microbiol. 35:1433-1444, 1997). Improvement was mainly due to the presence of VlsE and DbpA.

摘要

我们研究了先前描述的重组疏螺旋体免疫印迹试验(B. Wilske、C. Habermann、V. Fingerle、B. Hillenbrand、S. Jauris-Heipke、G. Lehnert、I. Pradel、D. Rössler和U. Schulte-Spechtel,《医学微生物学与免疫学》188:139 - 144,1999年)通过添加VlsE以及额外的DbpA和OspC同源物是否能够得到改进。通过使用一组来自36例神经莱姆病患者和67例对照患者的血清,重组免疫印迹试验的诊断敏感性显著提高(从52.7%提高到86.1%),且特异性未降低,并且高于传统全细胞裂解物免疫印迹试验(U. Hauser、G. Lehnert、R. Lobentanzer和B. Wilske,《临床微生物学杂志》35:1433 - 1444,1997年)(从63.8%提高到86.1%)。改进主要归因于VlsE和DbpA的存在。
