目前环境中细菌对抗菌素的耐药性有了显著增加;免疫损伤宿主中的进行性感染也变得愈来愈重要;同时又出现了一些抗病毒治疗的新方法。这些都迫切需要人们能对疾病做出特异、快速的诊断和及时、有针对性的治疗。一、单克隆抗体技术晚近,单克隆抗体(McAb)使人对免疫学方法在诊断传染病上的作用有了新的估价。在Kohler和Milstein所做的开创性研究的基础上, At present, the bacterial resistance to antibiotics in the environment has been significantly increased; progressive infections in immunocompromised hosts have also become increasingly important; and at the same time, some new methods of antiviral therapy have emerged. These urgently need people to make specific and rapid diagnosis of the disease and timely and targeted treatment. Monoclonal Antibody Technology Recently, monoclonal antibodies (McAbs) have given new insights into the role of immunological methods in the diagnosis of infectious diseases. Building on groundbreaking research by Kohler and Milstein,
