The study identifies a new variant of rotavirus P[8]G9 as the predominant strain in a pediatric population in Central Italy, highlighting continuous genetic drift and the need for ongoing virological surveillance.
Supports continued rotavirus strain surveillance in Italy; leaves open whether this G9 variant affects vaccine efficacy.
Rotavirus P[8]G9 was recognized as the most widespread genotype during a sentinel-based survey in Italy; phylogenetic analysis of the VP7 and VP4 genes showed that Italian isolates constituted a closely related genetic cluster distinct from the other G9 strains recently isolated in other European countries, America, and Asia.
