Abstract

The first description of pili of the gram positive bacteria, Corynebacterium renale was completed. The number and length of pili were different among types of C. renale. Generally, type I strains possessed only a few pili, 0.1~4μ long, while type II strains possessed numerous long pili, 1〜10μ. Pili of type II strains tended to form thick bundles, attached side by side. Occasionally the bundles attained a length of several ten micron. Piliation of type III strains was various, many strains possessed pili similar to those of type I strains, 0.1~2μ long, but some possessed many pili. The diameter of the pili was, regardless of types, approximately 25~30Å. Existence of an outer-most layer of cell wall and a well developed intracytoplasmic membrane system was also noticeable.
