细菌 L 型在临床上存在相当广泛,它是细菌因变异而产生的细胞壁不同程度缺损型,常在使用抗生素后产生。由于细胞壁缺损,细菌的形态及生物学性状发生改变,用常规方法不能检出。细菌 L 型早在1935年 Klienberger 在研究 Streptobacillusmonilformis 培养实验中发现用肉眼仅能看到的小菌落,因不明其生长意义,仅以所在研究所 Lister(英)字首命名。接着 Bacterial L-type exists in a wide range of clinical clinics, it is due to bacterial changes caused by varying degrees of cell wall defects, often after the use of antibiotics. Due to cell wall defects, the morphological and biological characteristics of bacteria change, using conventional methods can not be detected. Bacterial L As early as 1935 Klienberger in the study of Streptobacillusmonilformis culture experiments found only with the naked eye can see small colonies, because of unknown growth significance, only in the institute named Lister (British). then
