当机体受到布氏菌(抗原)的刺激,首先引起非特异性免疫反应,激活淋巴细胞后,建立特异性体液免疫反应,产生相应的血清抗体。不同时期的血清抗体反应,对于临床诊断、治疗、判断机体或群体感染状态,指导防治工作都有重要意义。为此我们选择不同时期布鲁氏菌病(下称布病)患者,用试管凝集试验(SAT)、补体结合试验(CFT)、酶联 When the body is stimulated by brucella (antigen), the first non-specific immune response caused by activation of lymphocytes, the establishment of specific humoral immune response, resulting in the corresponding serum antibodies. Serum antibody responses in different periods are of great significance for clinical diagnosis, treatment, judgment of the infection status of the organism or population, and prevention and control work. To this end, we selected patients with brucellosis at different stages (hereinafter referred to as brucellosis), using the tube agglutination test (SAT), complement fixation test (CFT)
