Immunoflorescence staining of Vero cells infected with (a) Sing-M105-02 isolate, (b) Sing-M100-02 isolate, and (c) EMCV(Aust) strain. The infected cells were allowed to react with porcine polyclonal antibodies raised against EMCV. The virus-infected Vero cells stained greenish yellow in the cytoplasm (), and at the perinuclear region (), indicating the presence of virus antigens. (d) Uninfected Vero cells stained red with counter stain. Magnification at x60.
