    Abstract:
    Group A rotaviruses (RVA) are the leading cause of acute gastroenteritis in young children, causing up to 450,000 deaths worldwide, mostly in developing countries. Most of RVA human infections in developed countries are related to five major G/P combinations: G1P[8], G2P[4], G3P[8], G4P[8] and G9P[8]. During the surveillance activity of RotaNet-Italy, three uncommon G3P[6] RVA strains, designated as RVA/Human-wt/ITA/NA01/2009/G3P[6], RVA/Human-wt/ITA/NA06/2009/G3P[6], and RVA/Human-wt/ITA/NA19/2009/G3P[6], were identified in the stools of children with diarrhea hospitalized in Southern Italy in 2009. Samples NA01, NA06 and NA19 were characterized as genotype G3P[6]. To investigate the three strains further, partial sequencing of the eleven genomic segments was performed. RVA strains NA01, NA06 and NA19 were found to share the rare genotype constellation: G3-P[6]-I2-R2-C2-M2-A2-N2-T2-E2-H2, which had not been reported previously in continental Italy. The phylogenetic analysis of the eleven genomic segments showed no evidence of zoonosis or inter-species reassortment at the origin of the Italian G3P[6] strains, indicating that they possessed DS-1-like genomic constellations similar to those detected previously in human cases in Africa and Europe. The analysis of the hypervariable regions of VP7 and VP4 (VP8*) revealed high amino acid identity between the Italian G3P[6] RVA strains involved in this study.
