Do blood agar support viral cultivation?
No, blood agar does not support viral cultivation. Blood agar is primarily used for culturing bacteria, as it contains nutrients that promote bacterial growth. Viruses require living host cells to replicate, so they cannot be cultured on standard agar media like blood agar.
What is meant CD8 or cytotoxic T cells?
A cytotoxic T-cell is a form of lymphocyte that is the "killer" T-cell. This cell engulfs damaged or viral/bacterial cells to stop them from infecting the blood.
What is difference between secondary bacterial infection of acute bronchitis and bacterial infection?
Secondary bacterial infections of the bronchi is an opportunistic infection where the normal bacteria that live in the nasal/oral region of the pharynx are able to infect the lungs. This usually occurs following a viral infection since the virus typically infects and kills the cells that make up interior lining of the bronchioles. This then causes a breach in this barrier which allow the bacteria to invade the tissues underneath and cause a response (bronchitis) by the immune system.

What are the compounds that kill bacterial cells without harming the cells of humans?
They are called antibiotics (meaning against life) and generally interfere in only a few specific chemical reactions, those found in bacterial cells but not human cells.
Short appendages used by some bacterial cells for adhering to surfaces called?
fimbriae
How can you damage your cells?
Bacterial or Viral infections are a couple of ways cells are damaged or killed.
Which cell will respond whether you have viral infection or bacterial infection?
bacterial..you can't really cure viral infections, only bacterial infections..hence anti-bacterial as antibiotics for a bacterial infection
What are viral or bacteria germs that invade body cells called?
Viruses, bacteria, and so on are called germs, infective agents, microbes, pathogens and so forth.
How is the viral nucleic acid core different from the nucleicid of the bacterial host?
bactrial DNA:- most bic / larger, but only one cell viral nucleic acid:- smaller then bacterial nucleic acid, but it has many cells
Why regular antibodies not be used as effective treatment of viral diseases but effective against bacterial infection?
Viral diseases are caused by viruses which live in our cells as a host. So, killing them by antibiotics means killing our own cells. This is why antibiotics are not effective against viral diseases.
Why is your nose blocked?
Because of inflammation and/or mucus build up, usually caused by viral or bacterial cells, or irritants such as pollen.
Is multiple sclerosis bacterial or viral?
It is neither bacterial nor viral. Multiple sclerosis is an autoimmune disease. That means that your body's immune system is attacking parts of your body. In the case of multiple sclerosis the immune system is attacking the protective cover around the nerve cells.
Does a high white blood cell count specifically indicate bacterial infection?
A high blood cell count that might indicate a bacterial infection is referring to white blood cells specifically. If a bacterial infection is present in the body, the immune system releases into the blood stream additional white blood cells to respond to the threat. A high count of these additional immune cells will then indicate that there is a bacterial presence to which the body is responding.
Do all cells need nucleolus?
Not all cells need a nucleolus. For example, bacterial cells do not have a nucleolus. A nucleolus is a dense body within the nucleus which is where ribosomes are formed. As viral cells do not create ribosomes, they do not need a nucleolus either...
When two bacterial cells temporarily join and directly transfer genetic material this is called?
Bacterial conjugation.

Abnormal division of cells that invade surrounding tissues is called?
cancer
