[Morphogenesis of Chlamydia].
A morphological investigation was carried out on more than 12 chlamydia strains of avian and mammalian origin, multiplied in chick embryos. A number of investigations were carried out under an electronic microscope, including 674 samples of concentrated and purified chlamydia as well as yolk sacs in ultrathin sections and in negatively contrasted preparations. In the cytoplasm of the cells we proved the presence of a chlamydial matrix, an autonomous synthesis of chlamydial bodies, the morphology and polymorphism of the chlamydiae, as well as the degenerative changes in the endodermal and endothelial cells in the yolk sacs of the chick embryos. Conclusions were drawn out that in the development of chlamydia in the chick embryos no intertransformation of chlamydial bodies and no binary divisions are observed, i.e. there are no proofs of the so-called cycle of development. The development of chlamydia in chick embryos takes place in the form of specific chlamydia morphogenesis which is characterized by an autonomous synthesis and morphogenesis of chlamydia bodies on the basis of a multivacuolated matrix.
