Abstract
A human astrovirus (HAstV) strain from Kenya was characterized by nucleotide sequence analysis. Sequences from open reading frame 1a (ORF1a) clustered with genotype 6/7, those from ORF1b clustered with genotype 3, and those from ORF2 clustered with genotype 2. A recombination point in the ORF1b-ORF2 junction was identified, with a second possible recombination point within the ORF1a region.
摘要
对肯尼亚分离的一株人星状病毒（HAstV）进行了核苷酸序列分析。ORF1a 的序列与基因型 6/7 聚为一簇，ORF1b 的序列与基因型 3 聚为一簇，ORF2 的序列与基因型 2 聚为一簇。在 ORF1b-ORF2 交界处鉴定到一个重组点，在 ORF1a 区域内还存在另一个可能的重组点。
