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.
对20世纪90年代在日本分离出的6株猫轮状病毒A(RVA)进行全基因组测序,结果显示出三种基因型组合,其中一种具有独特的G3-P[3]-I3-R3-C3-M3-A15-N3-T3-E3-H6组合。RVA/Cat-tc/JPN/FRV348/1994/G3P[3]携带的A15基因型是一种罕见的NSP1基因型,迄今为止,仅报道过一株人类RVA毒株和一株犬类RVA毒株携带该基因型。其他三株G3P[3]毒株(FRV72、FRV73和FRV303)具有I3-R3-C2-M3-A9-N2-T3-E3-H6组合,而两株G3P[9]毒株(FRV317和FRV384)具有I3-R3-C3-M3-A3-N3-T3-E3-H3组合。
