Molecular Characterization and Pathogenicity Analysis of Porcine Rotavirus A.

ABSTRACT: Porcine rotavirus A (RVA) is one of the major etiological agents of diarrhea in piglets and constitutes a significant threat to the swine industry. A molecular epidemiological investigation was conducted on 2422 diarrhea samples from Chinese pig farms to enhance our understanding of the molecular epidemiology and evolutionary diversity of RVA. The findings revealed an average RVA positivity rate of 42% (943/2422), and the study included data from 26 provinces, primarily in the eastern, southern and southwestern regions. Genetic evolutionary analysis revealed that G9 was the predominant genotype among the G-type genotypes, accounting for 25.32% of the total. The VP4 genotypes were P[7] (36.49%) and P[23] (36.49%). The predominant genotypic combinations of RVA were G9P[23] and G9P[7]. Eleven
