Why does the white blood cell (WBC) count go below normal with a viral infection?
I've read the a bacterial infection can cause high WBC count, but a viral infection can cause a low WBC count. Why does the WBC go lower with a virus, but go higher with a bacterial infection.
Well, maybe. You can actually see both high and low WBC counts with bacterial AND viral infections.
So why can the WBC count go below normal with a viral infection? First you have to try to determine WHY the WBC count is low. For example, a low white blood cell count can be the result of a prior infection - too many WBCs have been called into action and have been used up. This makes an individual more susceptible to outside infections like viruses. So when a blood test is performed, the WBC will be low, and the person will have a secondary viral infection going on.
However, there are viruses that can lower the number of a particular type of white blood cell. For example, with neutropenia, certain viruses (e.g. Hepatitis B virus) can decrease the production of neutrophils. So, you may see a below normal neutrophil count in a viral infection.
The cautionary tale is this - viral and bacterial infections can BOTH raise/lower WBC counts. Leukopenia can be seen in some viral infections (HIV) or severe bacterial infections. Leukocytosis can be seen in some viral infections (infectious mononucleosis) or bacterial infections. (+ info
What vitamins help to increase white blood cell count following a viral illness?
If my T-cell count is 450 and I still have a low viral load, am I gonna need meds real fast?
I am HIV+ and my lab results from 2 weeks ago show my t-cell count to be 450..which is down from 520 from the last time..My viral load is still relatively low..(8,000) Could my t-cells still rise on there own or do I need to start worring about meds?
Does the transformation from lytic to lysogenic activity contribute to the emergence of viral diseases?
Apparently it does. (+ info
Is this Viral Load and T-cell healthy for an HIV-positive person?
A friend of mine is HIV-positive, but I have a feeling that he is withholding information, because he does not want his friends/family to worry too much. I found out that his T-Cell amount is 22. And his Viral Load is about 300,000. How bad is that?
My first concern with your question is that you have his test results. How did you get them? That information is confidential and by LAW, can not be releast to anyone without the written consent of the patient. If your friend didn't give you the information, who did?
That said, if someone who has HIV has a T-cell count of 200 or less, AIDS is diagnosed. (+ info
Viral RNA uses normal processes of a cell to manufacture?
does it manufacture carbohydrates?
am i right?
The commonly-used chemical approaches for synthesizing nucleosides or nucleoside analogs can be classified into two broad categories: (1) those which modify intact nuceosides by altering the carbohydrate, the base, or both and (2) those which modify carbohydrates and incorporate the base,...

Can a viral "cold" cause your white blood cell count to be raised some? ?
My white blood cell count is 12.9
It is raised a little.
I have a common cold.
Could that be why it is a little elavated?
Could a yeast infection cause your white blood cell count to be raised?
The normal white blood cell count ranges from 4,000 to 11,000 per cubic. WBC can become elevated leucocytosis in response to infection ....such as an active infection e.g. active cold or flu and yeast infection.
White Blood Cell (WBC) Count -
WBCs (leukocytes) help prevent and fight infections in the body. The normal white blood cell count ranges from 4,000 to 11,000 per cubic millimeter in an average healthy adult. High WBC count may indicate that the body is fighting an infection. Low counts may be a result of certain drugs (AZT or ganciclovir), minor viral infections, stress, or opportunistic infections (tuberculosis, histoplasmosis, and other fungal infections). Low counts are cause for concern as the body becomes more susceptible to infection.
Viral Neurominidase, Besides Inhibiting the Release of Viral Particles From an Infected Cell, does it Also-?
-Serve In Breaking Down Secretions?
Viral neuraminidase is an enzyme on the surface of influenza viruses that enables the virus to be released from the host cell. Drugs that inhibit neuraminidase are used to treat influenza. Viruses particles consist of two or three parts: all viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Replication, influenza virus reproduces is more likely then secretions. Hope that helps! (+ info
is it possible for a viral cell or any cell to mutate into a deadly cancer cell?
1) A virus is not a cell.
2) Any cell in the body can mutate so that it has no controls on cell division, resulting in a tumor which can be benign or cancerous. (+ info
After Infection a virus is able to hide in the genome of a cell. What is this viral form called?
There are two types of virus.
The one you are referring to is the one that reverses the transcription of DNA and writes itself into the code. This is called a
retro virus, such as is HIV
When HIV is in the strand of DNA it is not yet infectious. At that point it is a provirus - an inactivated virus.
In fact there are vast areas in our DNA that are junk, they are retrovirus that were contracted by our ancestors and which we have managed to maintain inactive.
Do you know how the virus becomes active? (+ info
