Mechanism of Hepatitis B Virus

Millions of people are chronically infected with HBV worldwide despite the use of an effective vaccine. Those infected are at a high risk of developing liver cancer. Although current therapeutic regimens exist that can efficiently suppress viral replication of HBV, the virus has a unique replication strategy that enables the virus to persist within infected hepatocytes and eventually cause a relapse of viral activity within the infected individual. Progress in understanding HBV replication and the development of more effective therapeutic strategies aiming to achieve sustained viral control is hindered. Covalently closed circular DNA that is involved with viral production of the virus is not yet identified. The virological and immunological mechanisms that prevent vi...

Single-stranded RNA virus review

I enter the nerves of the diseased and cause inflammation of the brain in humans and other animals. I am present in more than 150 countries, with more than 3 billion people in regions of the world living where I exist. In 2015 alone, I caused about 17,400 deaths. I am the rabies virus. I belong to the Lyssavirus genus, which is composed of RNA viruses in the family Rhabdoviridae, order Mononegavirales. Like other lyssaviruses, I have a single-stranded RNA genome with negative sense. I have two major structural components: a helical ribonucleoprotein core (RNP) and a surrounding envelope. In my RNP, my genomic RNA is tightly encased by the nucleoprotein. My RNA genome encodes the five genes: nucleoprotein (N), phosphoprotein (P), matrix protein (M), glycoprotein (G), a...

Zika virus: symptoms and impact

The Zika virus is spread via mosquitoes, more specifically Aedes mosquitoes. The name Zika came from the Zika forest in Uganda.

The classification regarding this virus belongs to the family called Flaviviruses. Flaviviruses are a group of RNA viruses that cause human diseases. Other common viruses in the flavivirus family are usually yellow fever and the particular west nile virus. Yellow-colored fever is actually a virus that will affects the kidneys and liver, causing jaundice and fever that may be often fatal.

Influenza Virus Basic Concepts essay

There are various forms of influenza of influenza; those that have been identified include influenza A, influenza B, and influenza C. Type A usually results in causation of localized outbreaks seen in many places. Type B is known to cause sporadic occurrences of illnesses due to the viral mechanism, while type C is yet to be associated with major occurrences of illness conditions. Role of Antigenic Shift and Antigenic DriftThere are fundamental differences between antigenic drift and antigenic shift in the contemporary study of influenza virus: Antigenic Shift Antigenic shift primarily occurs when different strains (in essence more than two) interact leading to the subsequent formation of new subtype with an expression of different formulation of antigens. Antigenic shift occurs fro a...
