抗脆弱类杆菌和产气荚膜杆菌McAb池在外科感染快速诊断中的应用

目的 制备抗脆弱杆菌和抗产气荚膜杆菌单克隆抗体池，并用于快速诊断及时指导临床治疗。方法 采用间接免疫荧光抗体染色法（IFA）和免疫酶标抗体染色法（ELA）对我院1998～1999年191例外科感染患者的标本进行细菌学检测，并与常规培养法进行比较。结果 3种方法从191份标本中分别检出脆弱类杆菌53株（27.7%）和55株（28.8%）以及25株（13.1%）；检出产气荚膜杆菌12株（6.3%）和11株（5.8%)以及6株（3.1%）。IFA和ELA法2种厌氧菌检出率明显高于CM法。但IFA和ELA法之间检出率差异无显著性。结论 自制脆弱类杆菌和抗产气荚膜杆菌的McAb池，检测平时常见的脆弱类杆菌和战时常见的产气荚膜杆菌，敏感性高，简便，快速、便于推广。

Application of monoclonal antibody pool against Bacteroides fragilis and Clostridium perfringens in rapid diagnosis in surgical infection

Objective To prepare monoclonal antibody (McAb) pool against Bacteroides fragilis and Clostridium perfringens and evaluated its effect in rapid diagnosis in surgical infection. Methods After the preparation of monoclonal antibodies against B. fragilis and C. perfringens , 191 specimens collected from infectious patients was detected with indirect immunofluorescent antibody (IFA) and enzyme labeled antibody (ELA). The results were compared with routine cultural method (CM). Results Among the 191 specimens, 53 (27.7%), 55 (28.8%) and 25 (13.1%)strains of B. fragilis were detected with IFA, ELA and CM respectively, and for C.perfringens , 12(6.3%), 11(5.8%), and 6 (3.1%) strains were found. The detectable rate of anaerobic bacteria by IFA and ELA was higher than by CM, but no difference was found between these 2. Conclusion The self made McAb pool against B.fagilis and C.perfringens might be a rapid, specific, sensitive and simple McAb pool for detecting B.fragilis in surgical infection and C.perfringens in wartime.
