    摘要: Hepatitus A virus is grown in Vero cells after passage in in vitro cell culture. Virus replication and continued passage in Vero cells requires extended incubation times, up to about four weeks, for early passages and incubation temperatures no higher than about 32.degree. C. Continued passage results in a significant decrease in incubation time and an increase in virus yield. Cultivation of hepatitus A virus in Vero cells meets the development requirements for an inactivated human vaccine.

    摘要: Hepatitis A antigen obtained from the livers of non-human primates infected with hepatitis A (infectious hepatitis) virus has been found to be usable in fast, simple assays for hepatitis A antibody and thus usable in diagnosis of hepatitis A disease in humans, and for the preparation of hepatitis A vaccine.

    摘要: Hepatitis A virus is passaged at least once in a susceptible sub-human primate; the infected liver from such passage is used to inoculate an in vitro cell culture, the inoculated cell culture is incubated until hepatitis A antigen is detected in the cell sheet or culture fluid, and at least two serial in vitro passages in cell culture are carried out. The hepatitis A virus so modified can be used to prepare live, attenuated hepatitis A vaccine or an inactivated hepatitis A vaccine.
