No. Many organisms are harmless, and the body will produce antibodies since the organisms are seen as foreign.
Many pathogens (harmful organisms) may not cause significant disease in many people. An example would be the poliovirus - in some people it causes paralysis; in others it causes minor illness, in others it causes no symptoms. In all cases, the person develops antibodies.
Vaccination exposes the person to the antigens without the pathogen being present, and so antibodies are formed before the exposure, and this process does not result in illness.
What else can I help you with?
Active immunity is obtained when a person is exposed to what?
Antigens
Does a person get sick every time exposed to an antigen?
No. You are exposed to antigens all day every day. If you are allergic to the antigen then you may have an allergic reaction or not depending on a lot of factors such as the manner of exposure and the level.
Antibodies are produced when the body is exposed to?
soluble antigens whch entrs our body
What are produced when the body is exposed to antigens?
Antibodies.
Can you get sick if you ate something a mouse ate?
Absolutely but not definitely. People are probably exposed to much more bacteria in their day to day lives from rodents and insects than they realize and probably have had some immune response to the antigens to which they have been exposed.
What is the antigenic determinant site is that portion of the antigens exposed surface?
that's the part where the antibody attacks.
How has quarantine decreased the spread of communicable disease?
Quarantine is the practice of isolating a sick person from people who are not sick. Quarantine decreases the spread of communicable diseases by limiting the amount of people who are exposed to airborne germs.
Which of these determine a person's blood type and stimulate antibody formation?
Antigens determine a person's blood type. These antigens are present on the surface of red blood cells and stimulate the immune system to produce antibodies against incompatible blood types.
B lymphocytes exposed to antigens can transform into plasma cells and produce large quantities of antibodies?
True
Can you get sick from breathing on someone?
if the person is sick, and you are close enough to the person, then yes you can get sick. But if you are sick and you breath on someone, then that person could get sick. If you or the person who you are breathing on are both healthy, then it would be hard to get sick, in fact if someone is going to get sick, then it will be the person who you are breathing on.
What protects the body from free antigens?
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
Will you get sick from drinking water with ecoli?
Fresh bottled water should not make a person sick. Bottled water that is exposed to excessive heat temperatures may be harmful because of the toxins from the plastic bottle released into the water. A person would not feel the symptoms immediately making them sick although long term there could be effects.
