Publikováno v: Journal of General Virology. 84:1245-1251

The full-length genomic sequences were determined of Japanese swine and human hepatitis E virus (HEV) isolates (swJ13-1 and HE-JA1, respectively) with 100 % identity in the partial sequence of open reading frame (ORF) 2 (ORF2, 412 nt). swJ13-1 was is

TT Virus Is Distributed in Various Leukocyte Subpopulations at Distinct Levels, with the Highest Viral Load in Granulocytes

Autor: Fumio Tsuda, Hiroaki Okamoto, Junichi Kishimoto, Yuhko Gotanda, Shinichi Asabe, Masaharu Takahashi

Publikováno v: Biochemical and Biophysical Research Communications. 290:242-248

When TT virus (TTV) DNA was quantitated in whole blood and plasma aliquots from 27 viremic individuals by real-time detection PCR that can detect essentially all TTV genotypes, the TTV load was 6.9 +/- 3.5 (mean +/- standard deviation)-fold higher in

Sporadic acute or fulminant hepatitis E in Hokkaido, Japan, may be food-borne, as suggested by the presence of hepatitis E virus in pig liver as food

Publikováno v: The Journal of general virology. 84(Pt 9)

Among ten patients who contracted sporadic acute or fulminant hepatitis E between 2001 and 2002 in Hokkaido, Japan, nine (90 %) had a history of consuming grilled or undercooked pig liver 2–8 weeks before the disease onset. We tested packages of ra

Publikováno v: The Journal of general virology. 84(Pt 4)

Japanese patients with sporadic acute hepatitis E are infected with polyphyletic strains of hepatitis E virus (HEV). Hepatitis E is considered a zoonotic disease. Thus far in Japan, only three strains of swine HEV have been identified and an antibody
