title: [Heteromorphism of corynebacteria. I. Macrocells].
abstract: A possibility of formation of macrocells (MaC) of diphtheria bacilli was expressed to a different degree; the extreme expression are giant and supergiant forms. Giant forms with section dimension of 3--5micron retained their capacity to disorderly septation with the resultant formation of microcells (MiC). Apparently some of the septa were not realized. Supergiant forms were revealed as a layer and its transverse section. The length of the latter reached 30micron with the transverse section of 2--3micron. The layer has festooned contours with shallow invaginations, but marked day-like cuttings into the body (in case of transverse layer section). Septation of supergiant form was abortive in character. Both forms had homogeneous cytoplasm surrounded by a cell wall. In the supergiant form the latter was morphologically defective in the deepest part of the invaginates. The ultrastructure of both bacterial forms pointed to their rapid growth; however, the supergiant form was likely to be doomed to degeneration and chaotic disintegration.
