The Cytology of Smooth and Rough Variation in Bacteria Free

Abstract

Summary: In those members of the genera and studied, the constituent bacteria of Smooth cultures are typically unicellular, containing two chromatinic bodies. On division, a membranous septum is first formed, the bacillus subsequently dividing by constriction at this point.

The constituent bacteria of Rough cultures may comprise several cellular units, typically four, each containing a single chromatinic body and separated by membranous septa which, as growth proceeds, are transformed into true cell-wall septa, by the splitting of which the bacillus divides.
