The cytology and life-history of bacteria cytologylifehist00biss Year: 1955 120 THE CYTOLOGY AND LIFE-HISTORY OF BACTERIA Resting Stages Swarm Vegetative Reproduction THE LIFE-CYCLE IN EUBACTERIA AND MYXOBACTERIA be too keen to permit of the immediate success of a single transplant, of this kind. New substrates are more frequently introduced to micro-organisms already present, than vice versa, and are thus inoculated with a considerable number of spores or resting cells, derived from the last period of growth in the same area. In effect, therefore, the unit of growth and reproduction, in eubacteria as in myxobacteria, is the swarm or bacterial culture. The culture grows and ages, physically and physiologically, exactly Hke a multicellular organism, and differs from one mainly in the lack of speciaHsation of its component cells, hi myxobacteria some degree of speciahsation has been achieved in the formation of the various parts of the fruiting body, but in eubacteria all cells have an equal reproductive potential. The similarity between the cytology of the reproductive processes of the two groups makes it apparent that their life-cycles are basically ahke, and this similarity is increased by the existence o( the cytophagas which appear to be intermediate between them in many respects ; resembhng eubacteria in their saprophytic habit and absence o{ fruiting bodies, myxobacteria in the large microcyst and the morphology of the bacterium.
