Abstract

Rotavirus A (RVA) is the leading cause of acute gastroenteritis worldwide in both young children and animals. In this study, we analyzed the complete genome sequence of a rare G1P[4] rotavirus, which was identified from the stool samples (20130113) of an infant with diarrhea in Chongqing, China. The genotype constellation of strain 20130113 was G1-P[4]-I2-R1-C1-M1-A2-N2-T1-E1-H1. The results of both BLAST and phylogenic analysis indicated that 20130113 was likely generated by genetic reassortment between G1P[8] and G2P[4] strains that co-circulated during the season. Whether the emergence of this uncommon genotype reflects the establishment of a new RVA strain in the population requires continuous monitoring of rotavirus epidemiology.

Keywords: G1P[4]; Genotype constellation; Intergenogroup Reassortant; RVA.
