Full-genome sequencing of a Hungarian canine G3P[3] Rotavirus A strain reveals high genetic relatedness with a historic Italian human strain.

ABSTRACT

A canine Rotavirus A strain was identified in the fecal specimen of a young dog during 2012 in Hungary. The strain RVA/Dog-wt/HUN/135/2012/G3P[3] shared complete genotype constellation (G3-P[3]-I3-R3-C3-M3-A15-N2-T3-E3-H6) and high genome sequence similarity (nt, 98.8 %) with a historic human strain, RVA/Human-tc/ITA/PA260-97/1997/G3P[3]. This study provides evidence for the canine origin of the unusual NSP1 genotype, A15, and reinforces the hypothesis of direct interspecies transmission of canine rotaviruses to humans.
