| african strains of hepatitis e virus that are distinct from asian strains. | partial genomic sequences of four hepatitis e virus (hev) strains from africa (morocco and tunisia) and one from central asia (tashkent, uzbekistan) were obtained. the reverse transcriptase-polymerase chain reaction was used to amplify 5' and hypervariable regions of open reading frame 1 (orf1) and a region overlapping all 3 orfs. sequence analysis of these regions revealed the african strains to be quite distinct from all known asian strains but more similar to them than to the mexican strain. ... | 1997 | 9334924 |
