Abstract : Microglial cells in the hypothalamus of mice 2 to 4 days after inoculation of the JBE virus were observed in thin sections with the electron microscope. Virus particles 30 to 36 mu in diameter are found in vesicles, as dense spherical particles in OsO4-fixation and less dense in permanganate-fixation. Precursor particles 20 millimicrons in diameter have been noticed, which are originated from the nuclei. (Author)
