Preliminary Report of Cell Culture of Hepatitis E Virus
Abstract: Hepatitis E virus(HEV) was isolated in human embryomic lung cell inoculated with liver tissue suspension from an HEV-infected rhesus monkey, Slight cytopathic effect(CPE) appeared at the 27th day after 4 blind passages of viruses in cell culturs to at 17th day after 7 passages. Low amounts of 27—34nm virus-like particles(VLPs) in cell cultures were visualized by immunoelectronmicroseopy(IEM). 2 of 3 rhesus monkeys inoculated with 20ml of pool of cell cultures from 4 to 7 passages developed significant eleva...
