The morphology, ultrastructure of cells and the structure of microbial populations of various bacteria of the @entity5092 genus were estimated by electron microscopy. The strain 503 has been found to produce a bacterial population that is most homogeneous in shape and size. It contains microbes of only round and avoid forms, 0.5-0.6 micron in size. In addition of oval and round microbes there are ellipsoid and rod-shaped ones in the strains 15/3M, A. Cole 120, 117, etc. The largest @entity6588 microbes are typical of the strain Schu. The bacteria of all strains are covered by a capsule-like coat with well-defined borders. A thick capsule (0.12-0.35 micron) is specific for virulent strains whereas a thin capsular coat (0.06-0.12 micron) is encountered in vaccinal and avirulent microbes. The cells of the strain 503 were also shown to have the thickest envelope. All @entity6588 microbes have an asymmetric structure in the outer and cytoplasmic membranes due to the location of the bulk of intramembrane particles on their inner hydrophobic surfaces. Some @entity5092 microbes are able to produce keel-like protrusions on the outer membrane. The microbial @entity377 occupies 55-65% of the cytoplasmic volume and forms about 20-30 DNA-membrane contacts. Under unfavourable conditions, the microbes are capable of producing cell envelop protrusions and involutional cells, 0.1-0.3 micron in size.
