Fig. 5From: Crucial mutation in the exoribonuclease domain of nsp14 of PEDV leads to high genetic instability during viral replicationGenetic instability of E191A mutant. Sanger sequencing showed that E191A-P4 and the fecal sample collected at 2 dpi from the E191A-P1-inoculated pig#8 reverted to wildtype ExoN (GAG)Back to article page
