Full genotype constellations of six feline Rotavirus A strains isolated in Japan in the 1990s including a rare A15 NSP1 genotype

Full genome sequencing of six feline Rotavirus A (RVA) strains isolated in Japan in the 1990s revealed three genotype constellations, one of which had a unique constellation of G3-P[3]-I3-R3-C3-M3-A15-N3-T3-E3-H6. Genotype A15, carried by RVA/Cat-tc/JPN/FRV348/1994/G3P[3], is a rare NSP1 genotype, and only one human and one canine RVA strains have thus far been reported to carry this genotype. The other three G3P[3] strains (FRV72, FRV73, and FRV303) possessed a constellation of I3-R3-C2-M3-A9-N2-T3-E3-H6, whereas two G3P[9] strains (FRV317 and FRV384) possessed a constellation of I3-R3-C3-M3-A3-N3-T3-E3-H3.
