Cord formation is a characteristic property of the cultured Mycobacterium tuberculosis complex species. We describe a case of Mycobacterium marinum demonstrating robust cord formation. Nontuberculous mycobacteria can form true cords in broth culture but do so rarely, despite the fact that many species contain the cell wall glycolipid that mediates cord formation.
索状形成是培养的结核分枝杆菌复合群物种的一个特征属性。我们描述了一例海分枝杆菌表现出强大索状形成的病例。非结核分枝杆菌在肉汤培养中可形成真正的索状物,但很少见,尽管许多物种都含有介导索状形成的细胞壁糖脂。
