Summary
Electron microscopic examination of thin sections of vegetative cells and microcysts of S. myxococcoides indicates that the vegetative cells have a fine structure basically identical to that of other gram-negative bacteria. Microcysts, on the other hand, possess not only an extensive internal membrane system, an additional “intermediate layer” interposed between the plasma membrane and cell wall, but also a thick fibrillar outer coat or capsule.
