Characterization of Pseudorabies Virus Associated with Severe Respiratory and Neuronal Signs in Old Pigs

<div>Biological characteristics of different pseudorabies virus strains. (a) Virus titers of different pseudorabies virus (PRV) strains at different passages on PK-15 cells. (b) One-step growth curves of different pseudorabies virus (PRV) strains at different passages on PK-15 cells. (c) Plaques caused by different PRV strains on PK-15 cells observed under an electron microscope (bar = 1000 <i>μ</i>m). (d) Sizes of plaques caused by different PRV strains on PK-15 cells quantified using the ImageJ software.</div>
