| 英文摘要 | A human group b rotavirus strain wh-1 was detected in an adult sporadic case of diarrhea in wuhan, china in 2002. in this study, the gene sequences of wh-1 were determined in order to examine the phylogenetic relatedness to other human group b rotaviruses found previously in china (adrv, in 1982), india (cal-1, in 1998), and bangladesh (bang373, in 2000), as well as animal viruses, and to estimate the mutation rate of group b rotavirus. vp7 (major outer capsid protein) gene of wh-1 showed extremely high sequence identity (98.6%) to adrv and showed relatively high sequence identities to cal-1 (92.5%) and bang373 (92.4%). in contrast, identities to animal (bovine and murine) group b rotaviruses were considerably lower (61-64%). other gene segments of wh-1 encoding vp2, vp4, vp6, nsp1-nsp3, and nsp5 also showed high sequence identities to adrv genes (98-99%), which were generally higher than those to cal-1 genes and bang373 genes (90-95%). however, amino acid sequence identities between wh-1 and adrv were almost the same (vp2, vp6, and nsp3), or lower (nsp2) than those between wh-1 and cal-1 (or bang373). since rates of synonymous substitution and transition between wh-1 and adrv were similar for all the segments analyzed, genetic evolution was considered to have occurred neutrally and at a similar speed in most of the rna segments. based on the sequence divergence between wh-1 and adrv, the mutation rate in natural condition of human group b rotavirus was estimated as 7.9 x 10(-4) substitution/site per year. the frequency of synonymous substitution between adrv and bang373 was 5.7 times higher than that between adrv and wh-1, suggesting that the group b rotaviruses of indian-bangladeshi lineage diverged from that of chinese lineage several decades ago. |
