金葡菌L型是细菌变异而产生的细胞壁缺陷型。细菌变成L型后,其菌落、形态、生物学特性、致病性、药物敏感性均不同于细菌型。金葡菌L型败血症国内已有报告,引起呼吸道及肺部感染尚少见。本文报告10例有支气管和肺部感染的患者,他们的痰、血、骨髓普通肉汤培养阴性,只有L型培养生长典型的油煎蛋样的菌落。 Staphylococcus aureus L-type is caused by bacterial cell wall defects. Bacteria become L type, its colony, morphology, biological characteristics, pathogenicity, drug sensitivity are different from the bacterial type. Staphylococcus aureus L-type sepsis has been reported in the country, causing respiratory and lung infections are rare. This article reports 10 patients with bronchial and pulmonary infections, their sputum, blood, bone marrow normal broth culture negative, only the L-type culture of typical growth of egg-like colonies.
