Why does a particular vaccine give immunity against one disease only?
That is a good question! In the vaccine, you have few proteins, that are derived from particular organism only. The antibodies are very specific. They act against the particular proteins only. So from the given vaccine, you get specific antibodies. Those antibodies will act against that particular organism only.
What type of immunity provides lifetime protection for the body against a specific pathogen?
Active immunity
A type of immunity that defends against specific pathogens and gradually builds up resistance to it?
It is an acquired immunity
What are the two ways that people can be immunized against specific disease?
passive and active immunity
What type of immunity is a lifetime protection in the body against specific pathogens?
active imminity
What is an anarisum?
blood serum containing antibodies against specific antigens; provides immunity to a disease
What is the role of immunity in disease in animals?
Immunity is the internal protection of an organism from infection with a pathogen. Therefore, immunity (which is typically conferred by the immune system) has the role of protection against disease in animals. However, another aspect of immunity is innate or species-based immunity. This is conferred by the genetics of the species and protects the animal against pathogens that infect other species of animals. For instance, cattle are not susceptible to PRRS virus infection because PRRS is specific for pigs. This is not true of all diseases, however - viruses such as rabies and foot and mouth disease virus can infect multiple species.
What is positive immunity?
If a person's immune system is producing antibodies against a specific antigen, then that person has a positive or active immunity toward that antigen. If a person has merely been injected with antibodies but does not produce them, that is a passive immunity.
The process of vaccination?
Vaccination is the process of attempting to confer artificial immunity on an individual organism by exposing the immune system to antigens of the pathogen being vaccinated against. Vaccination does not provide nearly as good protection as natural, or acquired immunity.
What is a medicine that produces immunity by generating antibodies?
Vaccines are used to produce immunity by causing the body to generate antibodies. The antibodies can be directed against the organism causeing the illness or against a toxin produced by the organism. Also some allergies are treated by causing the body to develop blocking antibodies. In most cases injections are used to give the treatment. Oral polio vaccine is one exception to this.
What is the difference between the specific and nonspecific immune response?
Immunity provides protection against specific foreign antigens, displays memory, and it requires distinction between self and non self antigen.
What region in the immunoglobulin response to different antigens?
There are two types of immunity Humoral & Cell-mediated ; in humoral immunity plasma cells produces specific antibodies against a particular antigen that may invade the boby.
