“…Whatever the refractili t y or osmotic stability of these bodies may be, we feel that any set of parameters for determining whether or not a round body is a microcyst must include the ability to germinate. By direct observation under conditions suitable for microcyst germination we have never been able to demonstrate that these bodies, or similar bodies prepared by exposing vegetative cells to the sporulation medium of Adye & Powelson (1961), are capable of germination.…”

SUMMARYAn investigation has been made of the sequence of morphological events involved in the proccsses of microcyst formation and germination in the fruiting myxobacterium A4yxococcus xanthus. By using time-lapse photomicrographs and phase-contrast microscopy of living cells, microcyst formation is shown to involve a shortening and thickening of the entire vegetative cell with a subsequent increase of refractility. Germination is preceded by the casting off of a sheath followed by the gradual elongation and loss of refractility of the cell. Vegetative rods will readily form spheroplasts when exposed to a variety of conditions including sulphydryl compounds. The necessity for distinguishing between spheroplasts and microcysts is pointed out.
