Replication characteristics of eight virulent and two attenuated genotype 1 and 2 porcine reproductive and respiratory syndrome virus (PRRSV) strains in nasal mucosa explants.

Abstract excerpt

Porcine reproductive and respiratory syndrome virus (PRRSV) can spread in between pigs via contact and airborne route. It was shown before that the highly pathogenic PRRSV strain Lena was able to replicate 10-100 times more in the nasal mucosa compared to the low pathogenic PRRSV strain LV. In this work, the replication characteristics of four type 1 (LV, 07V063, 08VA, 13V091), three type 2 (VR2332, MN-184, VN)...
