Want this question answered?
because when it enter in body they become live and produce disease's out body they not produce disease.
macrophages engulf, or eat , any microorganisms or viruses that enter your body
The easiest way to understand how viruses replicate is to study the life cycles of viruses called bacteriophages (bacteria eaters). Bacteriophages replicate by either a lytic cycle or a lysogenic cycle. The difference in these two cycles is that the cell dies at the end of the lytic cycle or the cell remains in the lysogenic cycle. The virus remains "hidden".
Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply.
Impetigo can cause other diseases by weakening the immune system, allowing other forms of bacteria and viruses to enter the body.
causes Disease
The lytic cycle causes destruction of infected cells and their membrane. A virus that uses a lytic cycle reproduces itself or makes copies that are sent back into the environment and they are called virulent viruses.
actually the body does nothing to diseases. BUT. its what diseases do to tha body. thus, the body contracts all sorts of disease and viruses. when these foreign bodies (disease and virus ) enters the body, it is destroyed by white-blood cells which is the human bodys' main defence against viruses and diseases that wants to enter the body to make u i'll.
No medicinal cures, only your body's B and T-cells remembering and attacking the disease causing viruses the next time they show up... This poses a problem with viruses that mutate often as well as viruses like HIV that enter cells and reprogram the DNA inside the cells making them multiply with more and more bad copies of DNA...
capsids prevent viral infections apex they stop viral infections from reproducing
Many viruses enter the lytic cycle immediately following infecting the host cell. However, some viruses may not lyse their host immediately and enter the lysogenic cycle. At the start of the lysogenic cycle, the virus genome is integrated into the host chromosome instead of being immediately transcribed and translated. The virus genome then lies dormant in the host chromosome until a later event triggers its excision from the host chromosome. The excised viral genome will then be transcribed and translated and the virus enters the lytic cycle. the virus hides in the host's DNA.
Viruses can cause lytic infections or lysogenic infections. When a virus enters a cell to make copies of itself, causing the cell to rupture, that is called a lytic infection. A lysogenic infection is where a virus incorporates itself into the DNA of the cell it invades and replicates its genetic code.
