Susceptibility of Monkeys to Human Hepatitis A Virus

Journal of Infectious Diseases, 1981
A stump-tailed monkey, newly caught and without antibody to hepatitis B virus (HAV), was successfully infected with human HAV. The following alterations were observed in the monkey's functions: (1) elevation in activities of serum glutamic pyruvic transaminase, lactate dehydrogenase, and its type 5 isoenzyme (electrophoretically the fastest moving); (2)

Fecal Excretion of Hepatitis A Virus in Humans

Journal of Infectious Diseases, 1977
To define more completely the period of fecal excretion of virus during hepatitis A virus infection, we studied 24 fecal samples from six children with clinical illness during an epidemic of type A hepatitis. As determined by immune electron microscopy, the six patients had detectable viral excretion before or by the time of the first abnormality in ...

Validation of biocides against duck hepatitis B virus as a surrogate virus for human hepatitis B virus

Journal of Hospital Infection, 2006
The use of a surrogate virus, namely duck hepatitis B virus (DHBV), has been recommended for testing the virucidal activity of chemical biocides against hepatitis B virus. To date, however, this model has not been recognized as a standard test in European countries, as its laboratory use is associated with considerable difficulties. As previous studies

GBV-C/HGV: a new human hepatitis-related virus

Research in Virology, 1997
Two novel potentially hepatotropic flavi-like viruses were recently identified in patients with acute or chronic hepatitis and were provisionally called GBV-C and hepatitis G virus (HGV). The sequence identity analysis of these two viruses clearly indicated that GBV-C and HGV are two isolates of the same virus.

Propagation of hepatitis A virus in human embryo fibroblasts

Journal of Medical Virology, 1981
AbstractHuman diploid fibroblasts and human primary liver cell carcinoma cells (PLC/PRF/5) were infected with hepatitis A virus (HAV) adapted to growth in cell culture or derived directly from human stool. Viral antigen was expressed in PLC/PRF/5 cells 28 days after infection with cell culture‐adapted HAV, and 50 days after infection with virus from ...

Hepatitis A virus and hepatitis E virus prevalence relates to human immunodeficiency virus infection in Japanese male blood donors

Microbiology and Immunology, 2020
AbstractHepatitis A virus (HAV) has begun to spread globally among men who have sex with men (MSM). Hepatitis E virus (HEV) also may be transmitted through sexual contact among MSM. To assess the current status of these viruses among MSM in Japan, the seroprevalence of both viruses using 503 plasma samples collected between 2009 and 2018 from human ...

Characterization of a genetic variant of human hepatitis A virus

Journal of Medical Virology, 1992
AbstractHuman isolates of hepatitis A (HAV) are a single serotype; however, recent genetic surveys using limited nucleotide sequencing have provided evidence that more than one genotype is responsible for HAV infection in different parts of the world (Jansen et al. [1990]: Proc Natl Acad Sci USA 87:2867‐2871; Robertson et al.

Hepatitis A virus in cell culture

Medical Microbiology and Immunology, 1981
The propagation and adaptation of hepatitis A virus (HAV) in human embryo kidney cells (HKC) is shown. The growth curve of HAV in the first passage through HKC is compared to the growth curve in the tenth passage through HKC. It is shown that in the course of 18 passages through HKC, HAV adapted to these cells causing the virus to grow much more ...

Hepatitis C virus and human immunodeficiency virus: a dangerous dealing.

Panminerva medica, 2007
It is estimated that, in the United States and Europe, 15-30% of people with human immunodeficiency virus (HIV) are coinfected with hepatitis C virus (HCV). Among these patients, approximately 80% are intravenous drug users (IVDU), 71% are hemophiliacs, and around 20% are homosexual/bi-sexual men.
