淋病奈瑟菌在盖玻片上的流动细胞以及原代宫颈上皮细胞上形成生物膜。对10例宫颈活检标本进行了电镜研究。淋病感染显示在3个活检标本中有生物膜形成的证据。这些生物膜显示淋球菌在生物膜结构内的细菌膜网络中。在玻璃盖片上形成的生物膜中以及在体外原发性宫颈组织感染后也观察到该发现。用N.淋病菌株1291-msbB,其显示出明显降低的起泡能力。这种突变体在玻璃表面和宫颈上皮细胞上形成的生物膜显著减少,互补显示恢复到野生型生物膜。作为宫颈感染的一部分,淋病生物膜可能参与无症状感染、持续性和抗生素耐药性增加的机制。
Neisseria gonorrhoeae forms a biofilm in flow cells on glass coverslips as well as on primary cervical epithelial cells. Electron microscopic studies of cervical biopsy specimens from 10 patients with culture-proven N. gonorrhoeae infection revealed evidence of biofilm formation in 3 of the biopsy specimens. These biofilms showed gonococci in networks of bacterial membrane within the biofilm structure. This finding was also observed in biofilms formed over glass cover slips and after infection of primary cervical tissue in vitro. The importance of membranous networks in Neisseria biofilm formation was demonstrated with N. gonorrhoeae strain 1291-msbB, which shows a markedly decreased ability to bleb. This mutant formed significantly less biofilm over glass surfaces and cervical epithelial cells, and complementation showed reversion to wild-type biofilms. Gonoccal biofilms, as part of the cervical infection, may be involved in the mechanisms by which asymptomatic infections, persistence, and increased antibiotic resistance occur.
