炭疽病人发病3天后,开始产生抗炭疽荚膜抗体,可用免疫荧光法测出。发病4～7天同阳性率增至68.2％,一周后患者大多呈阳性。由于特异性的炭疽荚膜抗体只产生于炭疽显性感染患者体内,故在临床上可用于作炭疽病的早期快速诊断和鉴别诊断以及流行病学的追索诊断,本文结果比较满意。该法准确、快速、简易,值得推广。 Anthrax 3 days after onset, began to produce anti-anthrax capsular antibodies, immunofluorescence can be measured. The incidence of 4 to 7 days with the positive rate increased to 68.2%, most patients were positive after a week. Because specific anthrax capsular antibody is only produced in patients with dominant anthrax infection, it can be used clinically as an early rapid diagnosis and differential diagnosis of anthracnose and epidemiological recourse diagnosis, the results of this paper are satisfactory. The law is accurate, fast, simple, and worth promoting.
