The interaction of cells in microbial colonies has been studied by electron-microscopic techniques. Two types of contacts between cells have been found to exist in the colonies of Gram-negative bacteria of the genera Escherichia, Shigella and Salmonella: close cell adhesion due to the fusion of cell-wall outer membranes and the formation of intersections consisting of membranous tubules. At the sites of close adhesion the fusion of cytoplasmic and outer membranes have been found to occur in Bayer's zones. In the colonies of Gram-positive bacteria of the genera Staphylococcus and Brevibacterium only one type of contacts has been revealed: the fusion of the peptidoglycan layers of the cell walls. The results of this study indicate that in colonies bacteria are not completely isolated; their interaction leads to the formation of a three-dimensional structure denoted as a cooperative cell system.
