L型细菌是细菌在受外界某些条件制约而失去细胞壁的状态下,仍能继续繁殖的一类变异细菌的通称。自1935年Klieneberger发现以来,临床方面已有不少报道,但对血液培养中出现的情况报道较少。本文报告我们自1974年以来,在血液培养中发现L型细菌的情况,并对某些问题加以探讨。 L-type bacteria is a common name for a group of bacteria that can continue to multiply under the condition that the bacteria are restricted by certain external conditions and lose the cell wall. Since the discovery of Klieneberger in 1935, there have been many reports on the clinical aspects, but few reports on the occurrence of blood culture. This article reports on the discovery of L-type bacteria in blood cultures since 1974 and discusses some of the issues.
