细菌 L 型是细菌胞壁缺失后的一种变异现象,由 KLienebergier 首先发现,近年来,人们已逐渐认识了它的临床价值。国内、外已有大量资料佐证细菌 L 型主要由抗生素引起。细菌变为 L 型后,其生物学性状随之改变,常易造成漏检误诊。本文报道136例小儿细菌感染标本中分离出L 型细菌15株,并着重对其意义与特性作初步观察分析。 Bacterial L-type bacterial cell wall deletion is a variation of the phenomenon, first discovered by KLienebergier, in recent years, people have gradually realized its clinical value. There are a lot of data both at home and abroad to prove that the bacterial L type is mainly caused by antibiotics. After the bacteria become L type, its biological properties change, often misdiagnosis missed. In this paper, 15 strains of L-type bacteria isolated from 136 cases of bacterial infection in children were reported, and their significance and characteristics were emphatically analyzed.
