Abstract

Bacteroides forsythus is the first wild-type or mutant bacterium found to require exogenous N-acetylmuramic acid for proliferation and maintenance of cell shape. This implies so far unknown pathways for peptidoglycan synthesis and a strict dependence of B. forsythus on other bacteria in its oral habitat. Addition of N-acetylmuramic acid to conventional bacteriological media allows routine cultivation of this fastidious organism.

摘要

福赛斯坦纳菌是首个被发现的野生型或突变型细菌,其增殖和维持细胞形态需要外源性N - 乙酰胞壁酸。这意味着肽聚糖合成存在迄今未知的途径,且福赛斯坦纳菌在口腔栖息地对其他细菌有严格的依赖性。在传统细菌学培养基中添加N - 乙酰胞壁酸可实现这种苛求菌的常规培养。
