G26P[19] rotavirus A strain causing acute gastroenteritis in the American continent

Abstract

In Brazil, the rotavirus A genotype G26 was first identified in suckling piglets, while the P[19] genotype has not been identified in any animal species so far. This report details the genetic characterisation of a G26P[19] RVA strain detected from an eight year-old child, vaccinated with Rotarix®, hospitalised with acute diarrhoeal disease in Rio de Janeiro in 2015. Most likely, the genome constellation (I5-R1-C1-M1-A8-N1-T1-E1-H1) observed in the G26P[19] Brazilian strain was a result of interspecies transmission events between humans and pigs. In addition, a rearrangement in the NSP5 gene was observed downstream of the 3’ non-coding region.
