Virus

Virus, After the previous team we make an article about The Game Season 4 Episode 13 Now I will make an article about regarding Virus.

Virus, Studies on virus called Virology. Virus (latin) = poison. Almost all viruses can cause disease in other organisms. Currently the virus is the smallest-sized creatures. Viruses can only be seen with electron microscope and escaped from the filter bacteria (bacteria filter).

History of discovery
D. Iwanowsky (1892) and M. Beyerinck (1899) is a scientist who discovered the virus, when they examine the mosaic disease of tobacco leaves.

Then W.M. Stanley (1935) an American scientist succeeded in crystallizing the virus that causes tobacco mosaic disease (virus TVM).

Body Structure
Her body still not be called as a cell, composed of only a protein coat on the outside and nucleic acids (ARN & AND) on the inside. Based on the nucleic acid contained in the virus, we know the virus of AND and ARN virus. Viruses can only reproduce (replicate) in the living medium (embryo, animal tissue, plant tissue). The materials required to form parts of the body of new viruses, derived from the infected cell cytoplasm.

1. In Bacteria:
1.1. Bakteriofage.

2. In Plants:
2.1. The virus TMV (Tabacco Mosaic Virus) causes mosaic on leaves
tobacco.
2.2. Tungro virus: the cause of dwarf disease in rice. Transmission of the virus
this intermediary brown planthopper and green leafhoppers.
2.3. Virus GO (Citrus Vein Phloem Degeneration) attacked plants
orange

3. In Animals:
3.1. NCD virus (New Castle Disease) causes Newcastle disease in
chickens and ducks.

4. In Humans:
4.1. Hepatitis Virus, the cause of hepatitis (liver inflammation), the most
dangerous is Hepatitis B virus
4.2. Rabies virus>> cause of rabies
4.3. Polio Virus>> the cause of polio
4.4. Variola virus and Varicella>> cause of the fire smallpox and chickenpox
4.5. Influenza Virus>> cause of influenza
4.6. Dengue virus>> causes dengue fever
4.7. HIV virus>> that causes AIDS

How to prevent diseases due to viruses carried by the action of vaccination. The first vaccine was discovered by humans is smallpox vaccine, discovered by Edward Jenner (1789), while the oral vaccine invented by Jonas Salk (1952) in tackling the causes of polio. Humans are naturally able to make an anti-virus in his body, called Interferon, however humans can still be ill from a virus infection, because the speed of viral replication can not be offset by the speed of interferon synthesis.

Hopefully the post or article about Virus useful for you all, sorry if there are errors in writing words and discussion, still in the learning stage, greeting a success, hopefully you healthy always and thank you.
