[Morphological heterogeneity of Bordetella pertussis populations and clones (based on electron microscopy data)].
Populations belonging to different serovars of B. pertussis museum strains and antibiotic-resistant clones obtained from them have been studied by electron microscopy. As a result, morphological heterogeneity and differences in the ultrastructure of the cells with respect to the cell-wall structure, the character of the cytoplasm, the size of the cells, cytoplasmic inclusions and intracellular links have been demonstrated and, proceeding from these data, two main morphological variants of the cells have been defined. The cells of the morphological variant characterized by the pliciform surface of the outer membrane and the pronounced periplasmic space prevail among the populations of the museum strains. The possibility of the isolation of antibiotic-resistant clones, differing in their morphological structure and functional properties from the initial population, has been shown. The morphological diversity of B. pertussis population is the necessary condition for the existence and development of microbial populations.
