Abstract

Group A rotaviruses (RVA) are the main cause of acute viral gastroenteritis in both humans and animal. In the last decade, global surveillance of circulating RVA in the human population has revealed the presence of several uncommon genotypes, including Brazil. Many of these have been found in domestic animals, and phylogenetic analysis suggests that they arose in the human population through zoonotic transmission. The distribution and evolution of human RVA strains is important for vaccine development and effectiveness. In setting where RVA vaccine coverage is high, such as in Brazil, vaccine pressure could select for replacement of common strains with uncommon strains, some of which could be generated by reassortment between human and animal RVA. The detection of unusual/rare G and P genotypes association strongly suggest interspecies transmission. Tracking virus evolution and gaining an understanding of the role that animal RVA strains play is important for continued development of vaccine strategies and genotyping surveillance. Monitoring of RVA in the last 10 years (2009-2019) has allowed the identification of 5 rare RVA G12P[9] strains. VP7 (G) and VP4 (P) analysis only cannot determine the exact origin of these strains, and whether these infections were caused by zoonotic transmission. Only genotyping all 11 segments of RVA (genomic constellation) can clarify these issues. The aim of this study is to carry out sequence analysis of the 11 segments of five RVA G12P[9] detected during 2011-2013 in order to obtain further information on the genetic relationship between human and animal RVA.
