Herpes simplex virus (HSV-2, DNA virus) in cellular vacuoles and cytoplasm of peripheral blood lymphocyte (Herpesviridae Family). Two virus particles are seen adjacent to the cell membrane in the upper left of the image. The membrane near each virus is depressed and clatharin coated. This represents the classical receptor mediated endocytosis of virus particles. Herpes simplex is a viral infection. HSV-2 causes most of the genital herpes cases. Magnification*: x7,125 Type: TEM
