HEPATITIS VIRUS - Family That Damages Liver | Virology Notes

HEPATITIS VIRUSES

INTRODUCTION TO HEPATITIS VIRUS

⇒ Viral hepatitis is a systemic disease with primary inflammation in the liver by any one of a heterogeneous group of hepatitis virus.

There are six hepatitis viruses i.e., hepatitis A, B, C, D, E & G.

The designation ‘type F’ had been proposed for a putative virus believed to cause transfusion-associated hepatitis, later proved to be the mutant (HBx) of the type B virus & not a separate entity. Due to this reason type F was deleted from the list of hepatitis virus.

HEPATITIS A VIRUS (HAV) – MORPHOLOGY, TRANSMISSION, CLINICAL FEATURES & LABORATORY DIAGNOSIS

INTRODUCTION TO HEPATITIS A VIRUS (HAV) ⇒ Hepatitis A virus (HAV) was first demonstrated by the Feinstone & co-workers in 1973 by using immunoelectron microscopy (IEM). ⇒ HAV causes Type A hepatitis or Infectious Hepatitis, a subacute disease occurring mainly in children & young adults. MORPHOLOGY OF HEPATITIS A VIRUS ⇒ HAV is a 27 nm, non-enveloped, single-stranded RNA virus with an icosahedral symmetry. ⇒ HAV belongs to the Picornavirus ...

INTRODUCTION TO HEPATITIS B VIRUS (HBV) ⇒ HBV was first observed in 1965 & named as Australia antigen. Later, in 1968, it was found to be associated with serum hepatitis & the name has been changed to Hepatitis B Virus (HBV). ⇒ HBV causes Type B hepatitis, the most widespread and the most important type of viral hepatitis. ⇒ HBV is the only hepatitis virus that contains DNA as genetic material.

INTRODUCTION TO HEPATITIS C VIRUS (HCV) ⇒ HCV was identified during the research for ‘non-A non-B’ viruses by experimental infection in the chimpanzees. ⇒ HCV is the most common cause of post-transfusion hepatitis in the developed countries. ⇒ Infection due to Hepatitis C virus is seen only in humans. MORPHOLOGY OF HEPATITIS C VIRUS (HCV) ⇒ HCV belongs to Hepacivirus genus of Flaviviridae ⇒ Size – 50-60 nm in diameter ⇒ ...
