取６８例临床疑有败血症的患儿血液分别接种普通培养基和高渗Ｌ型细菌培养基。结果普通培养阳性９例，占１３２％；Ｌ型培养阳性３２例，占４７１％，在３２例Ｌ型阳性标本中，同时检出细菌型的有７例，２５例仅分离到Ｌ型，经返祖鉴定有金黄色葡萄球菌Ｌ型２６株，表皮葡萄球菌Ｌ型４株，大肠杆菌Ｌ型２株。本文并对分离到的细菌进行了药敏分析。 Sixty-eight children with suspected clinical sepsis were inoculated with normal medium and hypertonic L-form bacterial culture medium respectively. Results The results of routine culture were positive in 9 cases, accounting for 132%. There were 32 positive cases in L culture, accounting for 471%. Of the 32 positive cases of L type, 7 cases were also detected in bacterial type and 25 cases were only isolated L type, returned to the anomaly identified Staphylococcus aureus L-26 strains, Staphylococcus epidermidis L-4 strains, Escherichia coli L-2 strains. In this paper, the isolated bacteria were analyzed for drug susceptibility.
