The plasmid content of twenty-nine Neisseria meningitidis strains, isolated from CSF and blood cultures, was investigated by agarose gel electrophoresis. The strains (twenty-seven from serogroup B and two from serogroup C) were sensitive to antibiotics, but 50% were resistant to sulphonamide (MIC greater than or equal to 16 mg/l). Two serogroup-B strains from CSF harboured an extrachromosomal element. These two cryptic plasmids differed in size: 8.4 Kb for pNMT1 and 82 Kb for pNMT2.
通过琼脂糖凝胶电泳研究了从脑脊液和血培养物中分离出的29株脑膜炎奈瑟菌的质粒含量。这些菌株（27株来自B血清群，2株来自C血清群）对抗生素敏感，但50%对磺胺类药物耐药（最低抑菌浓度大于或等于16mg/L）。来自脑脊液的2株B血清群菌株携带一种染色体外元件。这两种隐蔽质粒大小不同：pNMT1为8.4kb，pNMT2为82kb。
