<div>Strain isolation and identification. (a) Virus inoculation in PAMs detected via IFA. (b) Electron micrograph of SL-01 (indicated by arrows). Magnification, 200,000x. (c) Cytopathic conditions and IFA revealing the reactivity of a monoclonal antibody against the PRRSV-N protein from SL-01 at 24, 48, 72, and 96 hr postinfection (hpi). Magnification, 400x. (d) SL-01 viral titer detection at 12, 24, 36, 48, 60, 72, 84, and 96 hpi. (e) Growth kinetics of SL-01.</div>
