“…In brief, RNA samples were reverse transcribed and amplified in a one-step procedure using the primer pair Beg9-End9 for the VP7 gene and the primer pair con2-con3 for the VP4 gene. Subsequently, multiplex nested PCRs were carried out using primers RVG9, aBT1, aCT2, aET3, aDT4, aAT8, and aFT9 for VP7 and primers Humcon5, P [4], P [6], P [8], and P [9] for VP4.…”
