- Abstract
The present study was conducted to monitor the genotypes of circulating species A rotavirus (RVA) in Iran and investigate genetic linkages between specific RVA VP7, VP4, VP6, and NSP4 segments. For this purpose, 48 RVA strains were detected during the 2021–2022 seasons. The two combinations of G9P[4] and G9P[8] RVA strains were predominant. However, several other combinations of RVA also were detected. Based on the distribution of I and E genotypes (46 strains) with respect to G and P, the most common strains were G9P[4]‐I2‐E2 (19.5%), G9P[4]‐I2‐E1 (6.5%), G9P[4]‐I1‐E1 (4.3%), G9P[8]‐I1‐E1 (19.5%), and G9P[8]‐I2‐E2 (10.9%), which were followed by several other combinations of G and P RVA strains with different pattern of I‐E genotypes and also emerging, rare and uncommon strains. The present study described the continued circulation of G9 strains with the emergence of uncommon G9P[4] and G9P[8] reassortants with three and two different I‐E genotypes, respectively, which have not been reported previously in Iran. Our findings indicated that these uncommon strains exhibited a unique genotype pattern comprising a mixture of genogroup 1 and 2 genes and suggest the need for further analysis of rare, uncommon, and emerging strains of RVA at all 11 gene segments to determine intergenogroup and intragenotype reassortments.
