What are Hepatotropic viruses?
What are Hepatotropic viruses?
Infections are caused by five hepatotropic viruses: hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV). It is estimated that 1.5 million new cases of hepatitis A and 20 million new cases of hepatitis E occur every year.
What are non Hepatotropic viruses?
Several non-hepatotropic viruses especially belonging to Herpes family like cytomegalovirus (CMV) and Epstein-Barr virus (EBV) can also cause hepatitis . In them, liver involvement is a part of the disseminated systematic disease, most often referred as non-A to non-E causes of viral hepatitis.
What are hepatitis viruses?
Viral hepatitis is an infection that causes liver inflammation and damage. Inflammation is swelling that occurs when tissues of the body become injured or infected. Inflammation can damage organs. Researchers have discovered several different viruses link that cause hepatitis, including hepatitis A, B, C, D, and E.
Which Hepatotropic virus is a DNA virus?
HBV. HBV is a relaxed, circular, partially double-stranded DNA virus from the family Hepadnaviridae (26).
Is hepatitis Ba DNA virus?
The hepatitis B virus (HBV) is a small DNA virus with unusual features similar to retroviruses. It is a prototype virus of the Hepadnaviridae family. Related viruses are found in woodchucks, ground squirrels, tree squirrels, Peking ducks, and herons.
Is hepatitis B an RNA virus?
Hepatitis B virus, a major worldwide infectious and cancer promoting agent contains a DNA genome of 3226 base pairs that replicates by a reverse transcriptase via an RNA intermediate.
Is EBV Hepatotropic virus?
Besides acute hepatitis during primary infection, many clinical syndromes of interest for the hepatologist are associated with EBV infection. The role of EBV in the evolution of chronic hepatitis from hepatotropic viruses is considered.
What is bacterial hepatitis?
Bacterial infection of the liver commonly results in pyogenic liver abscesses, acute hepatitis, or granulomatous (or chronic) liver disease. Pyogenic abscesses commonly involve enteric bacteria such as Escherichia coli and Klebsiella pneumoniae and are composed of multiple bacteria up to 50% of the time.
Is hepatitis viral or bacterial?
However, hepatitis is often caused by a virus. In the United States, the most common types of viral hepatitis are hepatitis A, hepatitis B, and hepatitis C.
Is hepatitis B RNA or DNA virus?
Is hepatitis Ba virus or bacteria?
Hepatitis B is a liver infection caused by the hepatitis B virus. Some people with hepatitis B are sick for only a few weeks (known as “acute” infection), but for others, the disease progresses to a serious, lifelong illness known as chronic hepatitis B.
Which is the most deadly virus worldwide?
The Marburg virus is considered the deadliest virus in the world, with a body count that will likely give any sane person the heeby-jeebies. Marburg is deadly because it takes its cues from its sister virus, ebola, in that the endgame is massive hemorrhaging and slow, agonizing, messy death.
How do you cure viruses?
Treatment of viral infections varies depending on the specific virus and other factors. However, treatment of viral infections generally includes rest, increased fluids, good nutrition, and may require hospitalization and intensive care, especially if complications occur.
What are some examples of viruses?
Examples of viruses that infect humans include chickenpox, measles, influenza, HIV, and herpes. Viruses gain entry into host cells via several sites such as the skin, gastrointestinal tract, and respiratory tract.
What is the cure for a viral infection?
The best cure for a viral infection is to have the virus and survive it. Your body will build up immunity to that particular virus and, usually, you will not have it again. Vaccines, although preventative, are a form of cure because they encourage your body to build immunity.
