title: [Morphological characteristics of lytic plaques produced by the SP1 strain of the equine herpes virus type 1].
abstract: Lytic plaques produced by three different strains of EHV 1 were morphologically compared. The local isolated SP1 strain was compared with the tissue culture adapted Kentucky B (Ky Bcc) strain, and the through hamster passages modified Kentucky B (Ky Ba) strain, both reference strains. Ky Bcc produced small, irregular in size and shape, lytic plaques of around 1 mm. In the case of Ky Ba, the plaques were uniform in size and shape, with a diameter of 2 to 3 mm. SP1 strain originated lytic plaques similar to those produced by Ky Bcc. It is concluded that SP1 is a wild abortigenic strain, similar to Ky Bcc regarding its lytic properties.
