What is difference between secondary bacterial infection of acute bronchitis and bacterial infection?
Secondary bacterial infection of acute bronchitis occurs when a viral infection weakens the airways, making it easier for bacteria to infect the lungs. Bacterial infection can happen independently of a preceding viral illness, leading to primary bacterial bronchitis. Both conditions may present with similar symptoms, but the underlying cause and treatment differ.
What is a group of bacteria cells called?
A group of bacterial cells is called a colony. This term refers to a visible cluster or grouping of individual bacterial cells that have multiplied and accumulated in a particular area.
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 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.
What are viral or bacteria germs that invade body cells called?
Viral germs that invade body cells are called viruses, while bacteria germs that invade body cells are called intracellular bacteria. Both can cause infections and lead to various diseases.
Which cell will respond whether you have viral infection or bacterial infection?
White blood cells are the immune cells that will respond to infections, including viral and bacterial infections. Different types of white blood cells play specific roles in detecting and fighting off infections by recognizing pathogens and coordinating the immune response.
How can you damage your cells?
Bacterial or Viral infections are a couple of ways cells are damaged or killed.
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.
How is the viral nucleic acid core different from the nucleicid of the bacterial host?
The viral nucleic acid core is composed of the genetic material specific to the virus and is often surrounded by a protein coat. In contrast, the nucleic acid of the bacterial host is the genetic material of the host bacterium and is usually localized within the bacterial cell. Additionally, bacterial nucleic acid is typically organized within a nucleoid region in the bacterial cytoplasm.
What is a group of bacteria cells called?
A group of bacterial cells is called a colony. This term refers to a visible cluster or grouping of individual bacterial cells that have multiplied and accumulated in a particular area.

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...
