Veroid Virus

When we hear the word virus, we usually think of something that makes us sick. A virus is an ultramicroscopic infectious organism that, having no independent metabolic activity, can replicate only within a cell of another host organism. A virus consists of a core of nucleic acid, either RNA or DNA, surrounded by a coating of antigenic protein and sometimes a lipid layer surrounds it as well. The viral genome provides the genetic code for replication, and the host cell provides the necessary energy and raw materials. To fight viruses, we use vaccines. While some may infect a broad range, other viruses can only infect certain kinds of cells. Vaccines are made of inactive, dead or weakened virus cells or protein antigens that can no longer infect

Viruses are a small infectious agent that can only multiply inside the cells of living organisms although unlike bacteria, fungi and parasites viruses are not

Bloodborne pathogens are viruses that deteriorate cells within the body. A virus is a submicroscopic parasitic organism that feeds on cells. Viruses are dependent on cells for their nutrients so the virus survive and reproduce. Every virus consists of

Viruses are microscopic particles that invade and take over both eukaryotic and prokaryotic cells. They consist of two structures, which are the nucleic acid and capsid. The nucleic acid contains all genetic material in the form of DNA or RNA, and is enclosed in the capsid, which is the protein coating that helps the virus attach to and penetrate the host cell. In some cases, certain viruses have a membrane surrounding the capsid, called an envelope. This structure allows viruses to become more stealthy and protected. There are two cycles in which a virus can go into: lytic and lysogenic. The lytic cycle consists of the virus attaching to a cell, injecting its DNA, and creating more viruses, which proceed to destroy the host. On the other hand, the lysogenic cycle includes the virus attaching to the cell, injecting its DNA, which combines with the cell’s DNA in order for it to become provirus. Then, the provirus DNA may eventually switch to the lytic cycle and destroy the host.

Viruses are coated genetic material that invade cells and use the cell's apparatus for reproduction.

A virus is a small capsule that contains DNA or RNA, viruses, unlike bacteria are not self sufficient and need a host in

Viruses - are extremely small particles made from protein and either DNA or RNA. They are not made up of cells instead they invade the living cells of other organisms and use them to produce many copies of

Unlike bacteria, that have everything it needs to reproduce, viruses need to use a living cell's organelles in order to replicate.

Smallpox is a highly contagious virus that has no known cure. Variola, is the name of the virus that caused one of the largest epidemics known to man. Smallpox killed nearly 500 million people in the 20th Century alone. Before Smallpox was eradicated it killed nearly 60% of all infected people. Smallpox has been coexisting with humans for thousands of years and has a very long history.

Smallpox is a highly contagious infectious disease. The type of microbe for smallpox is the Variola virus. Smallpox is caused by either the Variola major or the Variola Minor. This virus is spread by direct contact. The disease was likely to be in human populations about 10,000 BC. An epidemic broke out in 1519 with the Aztecs and the Conquistadors in Tenochtitlan Mexico. The epidemic killed a total of twenty five percent of the Aztecs population leaving it easy for Cortes and the conquistadors to take over the desired

The body responds differently to an infection, depending on whether it is a virus or a bacterial infection. Generally, viruses are considered to be more dangerous, but aside from generalities, there are also pathophysiological differences in the ways in which both viruses and bacteria (invasive organisms) infect human beings (hosts). When a virus is the agent that is infecting the host, the goal of the virus is to invade on a cellular level and replicate itself. “Once inside, the cells of the immune system cannot ‘see’ the virus and therefore do not know that the host cell is infected. To overcome this, cells employ a system that allows them to show other cells what is inside them” (Immune, 2015). The virus then uses the cell in order to make proteins and replicate itself, further compromising the immune system. The immune

The virus starts by getting a host cell and either uses it right away then kills it or kills right away usually they use it first. When the virus invades a body, It collides with the cell that spicks and propherances then they brush against each other and it if they fit together become one. The viruses is also able to hide from the immune system therefore avoiding being killed so it can reproduce. Then the virus gains control of a cell by injecting its genes into the cell and makes it do whatever it wants for the benefits of the virus not the cell. Of course while you have a cell doing the dirty work for you. The viruses make is own offspring/ copies of itself and takes of over and invading surrounding cells.

For example, viruses do not use energy and raw materials to grow and reproduce, and they are not made of one or more of the basic fundamental units of life – a cell. Compared to a cell, which includes organelles that enable the structure to grow and reproduce, a virus can only reproduce if another cell is present and that cell has organelles that the virus can inject its own DNA or RNA into and use it for its own replicating or mutating purposes. Viruses are made of a protein coat or capsid with its DNA or RNA genetic material enclosed inside of the capsid. In comparison, in addition to having organelles that use energy to help the cell develop, grow, and reproduce with the help of DNA, the cell by definition is enclosed in a membranous boundary,

A virus is a capsule containing genetic material, even smaller than bacteria. The main task of virus is to reproduce. However, viruses need a suitable host to

Some viruses also have an outer bag of lipo-protein called an envelope. After a virus attaches to a living cell, it either enters the cell to release the genetic information, or, the virus injects the information through the cells outer lining. Thus changing the cells natural functions and forcing the cell to spend its energy to create copies of the virus. The cell will go on making copies of the virus until the cell is used up and dies. The virus then leaves the dead cell and invades a nearby cell and the process starts all over. There are five types of human herpes virus: Varicella zoster which causes chickenpox, Epstein Barr virus which causes infectious mononucleosis, cytomegalovirus which can cause cytomegalic inclusion disease in infants, and herpes simplex viruses 1 and 2.
