| genetic analysis of the capsid region of astroviruses. | eight serotypes of human astroviruses (hastv-1 to hastv-8) have been described. to date, the entire genomes of hastv-1 and hastv-2 as well as the orf2 sequences of hastv-1-6 and 8 have been reported. in this study, the orf2 sequences of seventeen strains of hastvs originating from different countries were determined, as well as the sequence orf2 of one porcine astrovirus (pastv) strain. afterwards, comparison of the capsid protein precursors encoded by orf2 of 46 strains of hastvs, pastv, and fe ... | 2001 | 11424111 |
