我们对哈尔滨1990～1991年布鲁氏病轻、中、重病区,不同职业人群,用 SAT 与 RBPT 血清学方法进行血清抗体监测。在检测的787人中,血清学阳性106人,总血清阳性率13.3%。可见布病自然感染率是很高的。虽然在临床上没有定为病人,但不能排除布病发生的可能。在监测中看到病区内不同职业人群对布病感染率差异性很大, We conducted a surveillance of serum antibody against SAT and RBPT serological tests on patients with mild, moderate, and severe disease and different occupational groups in Harbin from 1990 to 1991. Of the 787 people tested, there were 106 seropositive patients with a total seroprevalence of 13.3%. It can be seen that the natural infection rate of brucellosis is very high. Although not clinically as a patient, but can not rule out the possibility of occurrence of brucellosis. Monitoring in the ward to see different occupational groups on the prevalence of brucellosis is very different,
