  • Title: [Electron microscopic study of the An-750 strain of Powassan virus isolated in the Soviet Union].
    Author: Sobolev SG, Shestopalova NM, Linev MB, Rubin SG.
    Journal: Vopr Virusol; 1978; (3):359-66. PubMed ID: 211734.
    Abstract:
    Electron microscopic examinations of brains of white mice inoculated with the An 750 strain isolated for the first time from adult mosquitoes and with the prototype LB strain of Powassan virus were carried out. The method of combination of light and electron microscopy used in the study permitted to compare ultrastructural changes in one cell with the results of light microscopy. Sizes of virions and their localizations in the brain cells were determined. Virus particles were found in large and small neurons as well as in glial elements. Subcellular changes in neurons associated with virus multiplication are described. The causes of differences in sizes of virions measured in ultrathin sections are discussed.
