摘要
淋病是我国近期流行的主要性传播疾病之一,常规进行淋球菌的分离培养以进行诊断,但费时费事。本研究利用金黄色葡萄球菌A蛋白(SPA)具有吸附IgG的Fc段的特性,建立了淋球菌的协同凝集(COA)试验。该法用于临床标本的检测和淋球菌菌株的鉴定,被证明为一种快速的鉴定淋球菌和诊断淋病的方法。
Gonococcal coagglutination assay reagent was produced on the basis of a SPA absorbent of specific antibody against Neisseria gonorrhoeae reference strains. Using this reagent, the assay could detect a minimum bacterial concentration of 10~6 CFU/ml. No crossreactivity was found with bacteria such as Escherichia coli, Staphylococcus aureus, Branhamella catarrhalis, Streptococcus faecalis, Pseudomonas aeruginosa and Neisseria meningitidis. Fifty-five Neisseria gonorrhoeae strains isolated from patient discharges in 1989 were screened in parallel wing Phadebact monoclonal coagglutination assay reagent and our reagent, the resulting correspondence rate was 100%. We examined 71 suspected gonorrhoea patients by detecting urethral discharges and cervical secretions with our reagent and compared the results with those of the standard culture method: the results were equivalent. It is concluded that this reagent can be used for the rapid identification of N. gonorrhoeae and for the rapid diagnosis of acute infective patients.
