Abstract

No major differences have been found in series of Staphylococcus aureus strains which reverted from 'L'-phase, either by pyrolysis mass spectrometry or by phage-typing or sensitivity testing. In 'L'-phase they have been subcultured for a long time or transformed/reverted many times into/from 'L'-phase. Plasmids were lost during transformations/reversions, but there was some difference between the tetracycline-connected plasmids on the one hand and the erythromycin-connected ones on the other.

摘要

通过热解质谱分析、噬菌体分型或敏感性测试发现,从“L”型回复的金黄色葡萄球菌菌株系列中未发现重大差异。在“L”型状态下,它们已被长期传代培养,或多次转化/回复为“L”型或从“L”型回复。在转化/回复过程中质粒丢失,但一方面与四环素相关的质粒和另一方面与红霉素相关的质粒之间存在一些差异。
