Abstract

The humoral responses to recombinant MPT-51 and GlcB was determined by using an enzyme-linked immunosorbent assay. Levels of immunoglobulin M (IgM) against MPT-51 and IgG against GlcB were higher among tuberculosis (TB) patients than among control individuals. When the MPT-51 and GlcB assays were combined, 90.8% specificity and 75.5% sensitivity were observed. MPT-51 and GlcB were recognized in the humoral responses of Brazilian TB patients.

摘要

通过酶联免疫吸附测定法确定对重组MPT - 51和GlcB的体液免疫反应。结核病(TB)患者中针对MPT - 51的免疫球蛋白M(IgM)水平和针对GlcB的IgG水平高于对照个体。当将MPT - 51和GlcB检测相结合时,观察到特异性为90.8%,敏感性为75.5%。在巴西结核病患者的体液免疫反应中识别出了MPT - 51和GlcB。
