title: [Peculiarities of cell wall ultrastructure of Nocardia dassonvilei].
abstract: Peculiarities of cell wall building and chemical content of Nocardia dassonvilei have been studied in conditions of culture growth and development. It has been established that according to the phases of actinomyces a mass of cell wall changes. In particular, it is maximal in logarithmic phase and minimal - in stationary phase. In the phase of dying an insignificant increase of cell wall is noted. It appears to be a result of the increase of amino acid content in peptic fraction of peptide-glycane in this phase. At the same time it has been established that according to the growth phases, in cell wall of the studied actynomyces the amount of teihoic acid appears to be a changeable value. In particular, it decreases from logarithmic to the phase of dying. The content of cell wall free polysaccharides also changes; their synthesis begins in logarithmic phase, reaches to maximum in stationary phase and is minimal in the phase of dying. According to the results of our investigations it has been established that chemical content of Nocardia dassonvilei cell wall is qualitatively stable in the dynamics of culture growth.
