Replication of the HEV genome:- ü HEV replicates in the hepatocytes and is excreted in stool ü A general model of HEV replication has been proposed, based on similarities and sequence homology to other more completely characterized +RNA viruses. ü As HEV enters into a permissive cell, the viral genomic RNA is translated in the cytosol of infected cells to produce the nonstructural ORF1-encoded polyprotein (nsP). ü Because it contains the viral replicase, nsP is postulated to replicate the genomic positive strand into the negative strand replicative intermediate. ü This intermediate, in analogy with alphaviruses, is postulated to act as a template for the synthesis of additional copies of the genomic positive strand as well as a subgenomic positive strand. ü The analogy to alphavirus replication is presumed because of the presence in HEV negative-strand RNA of a sequence stretch that is similar to the junction sequence found in the RNA replicative intermediate of the Sindbis alphavirus. ü During alphavirus RNA replication, this junction sequence acts as a subgenomic promoter for transcription of the structural region mRNA. ü The proposed subgenomic positive-strand HEV RNA can then be translated into the structural protein(s) at late stages of viral replication. ü The structural (capsid) protein then probably packages the viral genome to form progeny virions. ü However, direct experimental confirmation of this replication scheme is still awaited.

What is hepatitis E?
Hepatitis E is a viral hepatitis that mainly caused by infection.

E
Is hepatitis a viruse or a bacteria?
Hepatitis is actually quite a general term which means inflammation of the liver and so has many causes for example drug-induced, alcoholic, autoimmune or infectious. On the whole when most people refer to hepatitis they refer to infectious hepatitis often caused by the hepatitis viruses types B & C which have the potential to cause long term (chronic) hepatitis. There are other forms of the hepatitis virus family including types A, D & E and there are other forms of virus which can cause hepatitis. There are non-viral infectious causes of hepatitis including toxoplasma and Q fever (which is a bacteria) but these are rare.
What is hepatitis's vaccine name?
For Hepatitis A, it is usually just called "The Hepatitis A vaccine" but is marketed under the brand names Havrix and Vaqta. Hepatitis B is marketed under the brand name Comvax. There isn't a vaccine for Hepatitis C.
Como se llama el virus de la hepatitis e?
El virus de la hepatitis E se llama Virus de la Hepatitis E (HEV). Es un virus de ARN que se transmite principalmente a través de agua contaminada y causa hepatitis aguda en humanos.
Is there a vaccine for all hepatitis?
There is currently no vaccine available against Hepatitis C. There is research going on to develop one but it will take years at least before one is developed.
Is there a vaccine for Hepatitis?
Yes, but only for two types of viral hepatitis, hepatitis A and hepatitis B. There are no vaccines yet to prevent hepatitis C, D, or E. See the related question below for more information.
What is the name of the organism that causes hepatitis b?
Hepatitis B is a viral infection. It is a virus. Only one virus causes Hepatitis B. It infects the liver. A vaccine exists to prevent it. It is blood borne. If you are in the same room with someone who has it, you will not catch it. Do not share needles, razors, or anything that could move their body fluids to you. Hepatitis B can be treated. Other liver infections exist. Hepatitis A generally results when an infected person prepares your food. Hepatitis C is blood borne. Anything one person does that gets body fluids from one person into another spreads the virus. Hepatitis D, E, F, G, H, I, J, K, L, and M also exist. Those liver infections are caused by different pathogens. (I do not have the first idea about any of those diseases. Someone came back from Atlanta and passed on that information.)
Is hepatitis bacterial or viral?
Fever >> Viral low grade ,, Bacterial high grade Nonspecific symptoms >> such as URT symptoms roots for a viral vomiting and diarrhea which is first >> vomiting that proceeds diarrhea is more viral ,,, Diarrhea that proceeds vomiting is more bacterial Bloody >> favors bacterial though not sure bout that but epidemic infection usually viral many clues but the most accurate way is stool testing ..
What has the author Marcello Piazza written?
Marcello Piazza has written: 'Consuetudine e diritto costituzionale scritto' 'Experimental viral hepatitis' -- subject(s): Hepatitis A.
Hepatitis virus comes under which type of virus?
Several diseases of the liver, collectively known as hepatitis, are caused by viruses. The viruses involved, five of which have been reasonably well characterized, come from a wide range of virus families. Hepatitis A virus is a picornavirus, a small single strand RNA virus; hepatitis B virus belongs to the hepadnavirus family of double stranded DNA viruses; hepatitis C virus is a flavivirus, a single stand RNA virus; hepatitis E, also an RNA virus, is similar to a calicivirus. Hepatitis D which is also known as Delta agent is a circular RNA that is more similar to a plant a viroid than a complete virus.
