| 内容記述 | 1) ブタ糞便試料の18.0%(n=139)からHEVが検出され，濃度範囲は10^3～10^6PDU/gであった。 2) 6農場中5農場の養豚廃水からHEVが検出された一方で，処理後の養豚廃水からはHEVが全く検出されなかった。 3) 検出されたHEVはすべてG IIIに分類された。 4) 河川水から分離されたHEVは，河川流域に位置する養豚場の廃水から分離されたHEVと95%以上の相同性を示した。 |

| 内容記述 | Hepatitis E virus (HEV) is a single-stranded RNA virus which causes acute hepatitis accompanied by gastroenteritis. Most individuals with competent immune systems can overcome the infection within approximately one month, while pregnant women may suffer severe and fatal hepatitis with mortality rates up to 20 %. In developing countries, HEV is transmitted through waters contaminated by feces from infected individuals and sometimes causes large outbreaks. Although we have investigated the presence of HEV in environmental waters, including urban sewage and river water which may be contaminated by pig farm sewage, HEV RNA was not detected in any samples. HEV was detected in 25 of 139 fecal specimens from pigs aged 70 to 130 days in 14 farms. Moreover, high prevalence of HEV in pig farm sewage was observed (5/6 farms), suggesting that many fans are contaminated with HEV. However, HEV was undetected in treated sewage, indicating significant removal during sewage treatment processes. Testing of environmental waters in the vicinity of pig fans showed 3 of 28 samples positive for HEV. These positive samples were all taken from the Imaike River, with concentrations of approximately 10^2 PDU/L. All HEV isolates detected in the present study were sequenced and classified into G III. HEV isolates detected in environmental water samples showed high identities of 95.0 to 98.7 % with HEV isolates detected in pig farm sewage, indicating that HEV contamination in the environment may be originating from pig farms. |
