中文摘要:
      本文报告了用自己建立的BA-ELISA法和CoA法检测嗜肺性军团菌血清Ⅰ型(LP1)感染豚鼠和病人尿标本的结果。BA-ELISA法的灵敏度为0.1ng蛋白/ml,CoA法为60ng蛋白/ml。两法综合判断,军团病人的检出比为7/7。BA-ELISA法特异性较强,CoA法有4%的假阳性。
英文摘要:
      This article reported a Biotin-Avidin Enzyme-Linked Immunosorbent Assay (BA-ELISA) and a Coagglutination test (CoA) to detect Legionella-Soluble antigens in urine specimens of 38 artificially infected guinea pigs and 63 pati ents. The BA-ELISA was found to be able to detect as little as 0.1 ng protein/ml, and the CoA was 60 ng protein/ml.
The urine specimens of 7 patients with Legionnaires' Disease diagnosed by indirect fluorescent assay (IFA) were found to have positive result in both tests. No false positive result was found in BA-ELISA in patients suffering from Pneumonia other than Legionellosis as well as ‘healthy’ persons. 2 patients and 2 ‘healthy’ individuals, however, revealed false positive in CoA test.
