✦ Synopsis

The ultrastructure of microbial colonies was studied. Inside the colonics three types of intercellular contacts wcre demonstrated. In the colonies of Gram-negative bacteria, the cells were found to be connected by tight adhesions of outer membranes of the cell walls and membrane bridges. In the colonies of Gram-positive bacteria. the intercellular contacts were formed by fusion of peptidoglucan layers of the cell walls. Bacterial cells were differentiated by the presence of a capsule-like envelope. The obtained data indicate the existence of clements of cellular cooperation and specialization in microbial colonies.
