SUBMICROSCOPIC STRUCTURE OF PASTEURELLA PESTIS HOLLAND
Abstract
Electron microscopic investigations of capsular forms of P. pestis (vaccine strain) were carried out both on whole capsular cells, negatively stained with phosphotungstic acid, and on ultra-thin sections. On ultrathin sections the capsule is represented in the form of scraps of fibrillar material. Under the capsule there are 2 two-layered membranes: an outer membrane of the cell wall and a cytoplasmic membrane, separated by a layer of moderate electron optic density. In the cytoplasm ribosomes are revealed, as well as membranous structures of the mesosome type, unidentified electron-dense inclusions and nucleoids.
