３０株ＰＣＲ鉴定为淋球菌的变异株，与人工诱导的淋球菌Ｌ型相似。其形态为Ｇ＋和Ｇ－膨大双球菌或偶呈葡萄状，有细胞壁缺损及可滤过性。触酶试验（９３．３％）阳性、葡萄糖和氧化酶试验（９６．７％）转阴。形态及生化有与金葡菌相似处，借助ＤＮＡ酶和卵磷脂酶试验初步定鉴。金葡菌均为性阳，淋球菌变异株均为阴性，其中少数（３．３％）菌株ＤＮＡ酶试验阳性，故同时用ＰＣＲ检测可大大提高淋球菌检出率及准确率。 Thirty strains of PCR were identified as gonococcal variants, similar to the gonococcal L-form induced by humans. The form of G + and G-dilated meningitis or even grape-like, with cell wall defects and filterability. The catalase test (93.3%) was positive, and the glucose and oxidase tests (96.7%) turned negative. Morphology and biochemistry and Staphylococcus aureus are similar, with DNA and lecithin test preliminary Ding Kam. Staphylococcus aureus were all sexually positive, Neisseria gonorrhoeae variants were negative, a small number (3.3%) strains DNase test positive, so while using PCR detection can greatly increase the detection rate and accuracy of Neisseria gonorrhoeae.
