| identity of a novel swine hepatitis e virus in taiwan forming a monophyletic group with taiwan isolates of human hepatitis e virus. | recently, we found that more than 10% of the cases of acute non-a, non-b, non-c hepatitis in taiwan were caused by a novel strain of hepatitis e virus (hev). since none of these patients had a history of travel to areas where hev is endemic, the source of transmission remains unclear. the recent discovery of a swine hev in herd pigs in the united states has led us to speculate that hev may also circulate in herd pigs in taiwan and may serve as a reservoir for hev in taiwan. of 275 herd pigs obta ... | 1999 | 10565892 |
| clinical and epidemiological implications of swine hepatitis e virus infection. | in nonendemic areas, most patients with acute hepatitis e were infected through traveling to endemic areas. however, some patients did not have a history of foreign travel before infection. furthermore, high seroprevalence rates of antibody to hepatitis e virus (anti-hev) were found in the general adult population in some countries without any recorded outbreak of hepatitis e. the significance of anti-hev assay in these subjects remains obscure. to study if swine might be a source of hev infecti ... | 2000 | 10596016 |
| spread of hepatitis e virus among different-aged pigs: two-year survey in taiwan. | swine are reservoirs of hepatitis e virus (hev). in this study, a 2-year survey of hev in feces and sera of swine was conducted to determine if: 1) hev has circulated among pigs for some time in taiwan; 2) the spread of hev among different-aged pigs; and 3) there exists hev strains possibly imported through trading. from 1998-2000, 521 serum samples and 54 fecal specimens from pigs were examined by reverse transcription polymerase chain reaction. none of the 11 pigs in suckling stage (< 2 months ... | 2002 | 11857526 |
