Experimental infection of a US spike-insertion deletion porcine epidemic diarrhea virus in conventional nursing piglets and cross-protection to the original US PEDV infection

Although the original US porcine epidemic diarrhea virus (PEDV) was confirmed as highly virulent by multiple studies, the virulence of spike-insertion deletion (S-INDEL) PEDV strains is undefined. In this study, 3–4 day-old conventional suckling piglets were inoculated with S-INDEL PEDV Iowa106 (4 pig litters) to study its virulence. Two litters of age-matched piglets were ...

Determination of the infectious titer and virulence of an original US porcine epidemic diarrhea virus PC22A strain

The infectious dose of a virus pool of original US PEDV strain PC22A was determined in 4-day-old, cesarean-derived, colostrum-deprived (CDCD) piglets. The median pig diarrhea dose (PDD 50 ) of the virus pool was determined as 7.35 log 10 PDD 50 /mL, similar to the cell culture infectious titer, 7.75 log 10 plaque-forming units (PFU)/mL. 100 PDD 50 caused watery diarrhea in all ...
