Human immunodeficiency virus and hepatitis C virus/hepatitis B virus co-infection in Southern Brazil: clinical and epidemiological evaluation

Brazilian Journal of Infectious Diseases, 2014
Hepatitis B virus, hepatitis C virus and human immunodeficiency virus share a similar transmission pathway and are often diagnosed in the same patient. These patients tend to have a faster progression of hepatic fibrosis.

Purification of Hepatitis A Virus from Human Feces

Intervirology, 1978
Hepatitis A virus was purified fecal specimens obtained from 2 patients with naturally acquired hepatitis A. The purification procedure involved differential centrifugation, organic solvent extraction, agarose gel filtration, ion-exchange chromatography, and isopycnic ultracentrifugation in cesium chloride.

Seroprevalence of hepatitis A virus, hepatitis B virus, hepatitis C virus, and syphilis among human immunodeficiency virus-infected people at a university hospital, Turkey

Archives of Medical Science, 2020
IntroductionInfections such as viral hepatitis and syphilis that share similar transmission routes with human immunodeficiency virus (HIV) may adversely affect the course of the disease. We aimed to determine the seroprevalence of viral hepatitis and syphilis among HIV-infected people at the initial stage of diagnosis.Material and methodsThe medical ...

Biliary Secretion of Quasi-Enveloped Human Hepatitis A Virus [PDF]

mBio, 2016
ABSTRACTHepatitis A virus (HAV) is an unusual picornavirus that is released from cells cloaked in host-derived membranes. These quasi-enveloped virions (eHAV) are the only particle type circulating in blood during infection, whereas only nonenveloped virions are shed in feces. The reason for this is uncertain.

Prevalence of a virus similar to human hepatitis B virus in swine [PDF]

Virology Journal, 2010
Abstract Background The objective of this study is to established evidence of the existence of a novel member of the hepadnavirus family endemic in swine. Temporarily this virus was designated as swine hepatitis B virus (SHBV). This SHBV can be detected by using human hepatitis B virus diagnostic kits including ELISA,

The use of non-human primates as animal models for the study of hepatitis viruses

Brazilian Journal of Medical and Biological Research, 1998
Hepatitis viruses belong to different families and have in common a striking hepatotropism and restrictions for propagation in cell culture. The transmissibility of hepatitis is in great part limited to non-human primates.
