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

<div>Evaluation of viral virulence using mouse models. (a) Study design of mouse experiment. (b) The survival curve of experimental mice challenged with different pseudorabies virus (PRV) strains. (c) Detection of viral DNA in different murine tissues by real-time quantitative PCR. (d) Histological examinations of the murine lungs from different challenged mice (bar = 100 <i>μ</i>m). (e) Histological examinations of murine brains from different challenged mice (bar = 200 <i>μ</i>m).</div>
