hello
What else can I help you with?
Can a virus have cells?
No, a virus cannot have cells.
What is a generalist virus?
It infects many kinds of cells in many different hosts.
Is a virus made up of a cell or cells?
No, a virus is not made up of cells. It is a small infectious agent that can only replicate inside the cells of living organisms.
What is the first event that occurred when a virus infects the host cell?
The virus attaches to the host cells membrane.
A Virus Has No Outer Membrane Is it a cell?
Virus have no cells
Can you find cells in a virus?
You would not find any cells inside a virus. A virus is a small infectious particle and is actually much smaller than most cells. You will find either DNA or RNA in a virus, but never both.
What virus attacks the cells in the immune system that produces that antibodies?
HIV, human immunodeficiency virus, is the virus that attacks the cells in the immune system that produce antibodies.
What do cells infected with the Epstein-Barr virus look like under the microscope?
The cells infected with Epstein-Bar virus do not have any special look. You can see the peripheral blood smear with many lymphocytes. Some of them are atypical.
Do all the microbes have cells?
Virus do not have cells.Other microbes have cells.
What is permissive and non permissive cells?
Permissive cells are capable of supporting the replication of a virus, whereas non-permissive cells are unable to support virus replication. In permissive cells, the virus can enter, replicate, and exit to infect other cells. Non-permissive cells may lack the necessary factors or receptors for the virus to complete its replication cycle.
How does AIDS cause a particular disease?
The virus that causes AIDS is called HIV. This virus uses one of the main type of immune cells - CD4 cells - to reproduce. The immune response to infection is to produce more CD4 cells, which the virus uses to reproduce even more etc. The immune system initially controls the virus. However, without treatment, usually over many years, the virus slowly wears down the number of CD4 cells. This leaves someone vulnerable to a wide range of serious infections.
What destroys body cells that are infected with a pathogen?
It depends on the pathogen. If it is a virus, the virus will replicate (reproduce its DNA) inside the cell (known as a host cell). The virus clones will then leave the cell and in doing so, cause the cell to die. When this happens many many times, lot of the cells of a tissue die and the tissue itself will start to fail. If it is a bacteria, the bacteria release toxins (endotoxins) which kill the cells directly (from outside).
