Hepatitis E virus (HEV) is an important human pathogen. In addition to humans, HEV has also been identified in pig, chicken, mongoose, deer, rat, rabbit and fish. There are four recognized and two putative genotypes of mammalian HEV. Genotypes 1 and 2 are restricted to humans, while genotypes 3 and 4 are zoonotic. The recently identified rabbit HEV is a(More)
Porcine reproductive and respiratory syndrome virus (PRRSV) is an important swine pathogen. Here we applied the DNA shuffling approaches to molecularly breed the PRRSV GP3 gene, a neutralizing antibodies inducer, in an attempt to improve its heterologous cross-neutralizing ability. The GP3 genes of six different PRRSV strains were bred by traditional DNA(More)
Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most economically important swine pathogens, which causes reproductive failure in sows and respiratory disease in piglets. A major hurdle to control PRRSV is the ineffectiveness of the current vaccines to confer protection against heterologous strains. Since both GP4 and M genes of(More)
Hepatitis E virus (HEV) is a single-stranded, positive-sense RNA virus in the family Hepeviridae. Hepatitis E caused by HEV is a clinically important global disease. There are currently four well-characterized genotypes of HEV in mammalian species, although numerous novel strains of HEV likely belonging to either new genotypes or species have recently been(More)
Hepatitis E virus (HEV) is a single-strand positive-sense RNA virus in the family Hepeviridae. The disease caused by HEV, hepatitis E, is an important public health problem in developing countries of Asia and Africa and is also endemic in many industrialized countries, including the United States. HEV has been identified from several other animal species in(More)
Hepatitis E virus (HEV) is an important but extremely understudied human pathogen. Genotypes 1 and 2 are restricted to humans, whereas genotypes 3 and 4 are zoonotic, infecting both humans and pigs. This report describes, for the first time, the successful rescue of infectious HEV in vitro and in vivo from cloned cDNA of a genotype 4 human HEV (strain(More)
Hepatitis E virus (HEV) is an important human pathogen with pigs and other species serving as natural animal reservoirs. Ample evidence documents sporadic cases of hepatitis E acquired via consumption of undercooked meat. Chronic hepatitis E cases in immunosuppressed individuals are mostly caused by zoonotic HEV of swine origin. We report here the(More)
Hepatitis E virus (HEV), the causative agent of hepatitis E, is a single-stranded positive-sense RNA virus belonging to the family Hepeviridae. At least four genotypes of the family infect humans: genotypes 1 and 2 are transmitted to humans through contaminated water, while genotypes 3 and 4 are zoonotic and have animal reservoirs. A novel strain of HEV(More)
