| 摘 要： | 从1株临床分离的淋病奈瑟菌(N.gonorrheae,Ng)分别检测出耐氨苄青霉素(AMPr)及四环素(TCr)的2种质粒(R质粒),其分子量分别为25.2 Mu和4.5 Mu.进一步研究发现,编码TCr的质粒也编码普通菌毛,因而与其粘附性有关.消除此R质粒不但细菌的TCr消失,电镜下观察其菌毛几乎全部消失,其粘附性也显著降低,故此R质粒也被确认为是粘附性质粒(Adh质粒). |
| 关 键 词： | 淋病奈瑟菌 粘附性 质粒 |

| Abstract: | Two R plasmids encoding with tetracycline resistance TC r of MW 25.2 Mu and 4.5 Mu ampicillin resistance AMP r were detected from a Neisseria gonorrheae strain N.g 141 respectively. The R plasmids were found to encode ordinary pili as well as adherence of bacteria to urinary epithelia in further study. After curing the plasmids both of TC r and adherence disappeared, observation under electromicroscope no pili were found. These indicated that the R plasmids were adherence plasmids. |
| Keywords: | Neisseria gonorrheae adherence plasmid |
