Abstract

A simple enzyme-linked immunosorbent assay was developed for the identification of cultured mycobacteria belonging to the Mycobacterium tuberculosis complex, the Mycobacterium avium complex, and Mycobacterium kansasii. Six monoclonal antibodies were used: two (F23-49 and F24-2) were specific for the M. tuberculosis complex, two (F85-2 and F85-10) were specific for the identification of the M. avium complex, one (F126-22) was specific for M. kansasii, and one (F141-3) was broadly reactive and distinguished mycobacteria from other bacteria. In the enzyme-linked immunosorbent assay only 10(6) to 10(7) bacteria derived from early cultures (2 to 3 weeks) were needed for each monoclonal antibody. For the M. tuberculosis complex the sensitivity and specificity were both 100%. For the M. avium complex the specificity was 100% and the sensitivity was 70%. The three M. kansasii strains tested could all be identified as M. kansasii.

摘要

开发了一种简单的酶联免疫吸附测定法,用于鉴定属于结核分枝杆菌复合群、鸟分枝杆菌复合群和堪萨斯分枝杆菌的培养分枝杆菌。使用了六种单克隆抗体:两种(F23 - 49和F24 - 2)对结核分枝杆菌复合群具有特异性,两种(F85 - 2和F85 - 10)对鸟分枝杆菌复合群的鉴定具有特异性,一种(F126 - 22)对堪萨斯分枝杆菌具有特异性,一种(F141 - 3)具有广泛反应性,可将分枝杆菌与其他细菌区分开来。在酶联免疫吸附测定中,每种单克隆抗体仅需要来自早期培养物(2至3周)的10⁶至10⁷个细菌。对于结核分枝杆菌复合群,敏感性和特异性均为100%。对于鸟分枝杆菌复合群,特异性为100%,敏感性为70%。所测试的三株堪萨斯分枝杆菌均能被鉴定为堪萨斯分枝杆菌。
