L型细菌的特点为菌细胞的细胞壁不同程度的缺陷。细胞壁缺陷后,细菌呈多形性,可通过0.45μ除菌滤膜,革兰氏染色阳转阴,大多要在高渗环境中繁殖,菌落呈“油煎蛋”样为其特征,其形成与长期使用抗生素有关。抗体、补体、溶菌酶等对其形成亦有影响,多数文献均论述L菌与长期慢性反复发作的疾病有关。我室在作临床标本的L型菌的分离培养中发现1例烧伤败 L-type bacteria are characterized by different degrees of cell wall defects. After cell wall defects, the bacteria was pleomorphic, through 0.45μ bacteria filter, Gram staining positive and negative, mostly to reproduce in hypertonic environment, the colony was “fried egg” as its characteristics, the formation of And long-term use of antibiotics. Antibodies, complement, lysozyme also affect its formation, most of the literature discusses the L bacteria and long-term chronic recurrent disease. My room in clinical specimens for the isolation and culture of L-type bacteria found in 1 case of burn defeat
