The retrovirus HIV

This is an envelope virus. The virus is 90-100 nm in size by an outer membrane (lipid bilayer) environments, are incorporated into the glycoprotein spikes. In the outer membrane is a further shell, the capsid, a helical protein structure that surrounds the nucleic acid core, which contains the genome, that the series is to single-out two (2) copies of RNA and contains 7000-11000 nucleotides. The single-stranded RNA

(genetic material) of the retrovirus is transcribed by the enzyme reverse transcriptase (RT) to DNA and integrated into the genome of the host cell.

HIV virus species or strains of HIV virus

The two previously known strains of HIV are known as HIV-1 and HIV-2. These are similar in structure, but differ in their serological properties. Both are divided into subtypes, which have large differences in the geographical distribution.

of HIV-1 there are two (2) subgroups (occurs mainly in Cameroon and the U.S.) with M and O are known. The group M is further divided into nine (9) subtypes, labeled A (especially in Central and Eastern Africa and Europe), B (especially in Europe, Central Africa, North America, South America, India and Indochina), C (Central and Southern Africa, Europe, India and Indochina), D (Central Africa and Europe), E (Central, Eastern and Southern Africa, Europe, India and Indochina), F (Central Africa, South America and Europe), G (Central and West Africa and Europe), H (Central Africa and Europe) and I (known in the Middle East). The less pathogenic HIV-2 is divided into five (5) sub-groups, with A (worldwide), B (particularly in West Africa, Europe and India), C (West Africa), D (West Africa) and are called E (West Africa).

What will actually be HIV and AIDS was called?

as HIV, the virus is known. The human immunodeficiency virus (HIV) is a spherical retrovirus with a relatively complex genome, which belongs to the family of lentiviruses. The virus infects the cells, especially of the immune system, increases in them, it is out of action and finally destroyed it.

the disease as a result of Infection with the HIV virus was given the name AIDS (Acquired Immune Deficiency Syndrome). AIDS caused by HIV-induced weakening of the immune system, making the body defenseless against many pathogens susceptible to tumors - to ward off a healthy person without any problems - and eventually leads to death without treatment.
