随着医学检验技术的发展,对伤寒副伤寒的诊断从病原学诊断,肥达氏反应逐渐发展有对流免疫电泳法,杀菌抗体试验法,炭凝集试验法、酶联免疫吸附试验法、胶孔凝集试验法和SPA(甲型副伤寒杆菌)协同凝集法等多种诊断方法,这些方法的建立有利于伤寒的早期诊断,也大大提高了伤寒副伤寒的诊断率。但是目前在我国伤寒副伤寒的病原学诊断和肥达氏反应仍被广泛使用。特别是缺乏细菌室的广大基层医院(如乡镇医 With the development of medical testing technology, the diagnosis of typhoid fever paratyphoid diagnosis from the etiology, Wadda’s response to the progressive development of convective immuno-electrophoresis, bactericidal antibody test, carbon agglutination test, enzyme-linked immunosorbent assay, gel Agglutination test and SPA (Salmonella paratyphi A) co-agglutination and other diagnostic methods, the establishment of these methods is conducive to the early diagnosis of typhoid fever, but also greatly enhance the diagnosis of typhoid and paratyphoid fever. However, the etiological diagnosis of typhoid and paratyphoid fever and Widal reaction in China are still widely used. In particular, the majority of grass-roots hospitals lacking a bacterial room (such as township doctors
