Types of Immune

Types of Immune - this time to be discussed are the types of immunity. Judging from how to get it, immunity is divided into two, namely active immunity and passive immunity. Both this immunity is acquired naturally and there is also obtained artificially. Following further discussion: 

Active Immunity 

Active immunity is an immunity which is formed by the body itself. Own body to form antibodies due to antigen infection. This active immunity can be obtained naturally artificially. 

Naturally acquired active immunity when a person is stricken with an antigen (seedling diseases, especially micro-organisms). At the time this person is sick in his body developed humoral and cellular immunity against germs, then the person will recover and become immune to the disease. For example, people who have had measles disease, measles, and mumps will not be affected by the disease a second time. 

Active immunity can also be obtained artificially. artificial active immunity can be obtained by inserting an antigen that has been weakened or already dead into the body. The aim is that the body is able to form antibodies without causing illness or toxoid.

The vaccine is a suspension of micro-organisms or parts of organisms (viruses or bacteria) that have been dead or weakened. The toxoid is a toxin or toxic substances that have been weakened. Examples of vaccines that may have a friend pustakers see, eg polio vaccine. 

Passive Immunity 

Passive immunity is the immunity acquired from outside. Immunity acquired in or inserted into the body. passive immunity is acquired naturally and there is also obtained artificially. 

natural passive immunity can be found in infants. Babies will acquire passive immunity from mother nature. This can occur because of maternal IgG to break through the placenta and into the body of the fetus. Therefore, at the time of birth until the age of 6 months the baby will have a natural passive kekbalan it. This condition is supported also by the provision of IBI or breast milk of the first (colostrum), which contains antibodies. 

In addition to naturally derived, passive immunity can also be obtained artificially. artificial passive kekbalan obtained by injecting gamma-globulin (IgG) or other imunoglobulen obtained from the blood of people who are already immune to a disease. However, this artificial passive immunity lasts only a few weeks just because immunoglobulins originating from outside the body will be described by the body of the person. Examples of other artificial passive immunity, namely the provision of anti snake venom serum in people who pecked (bitten) poisonous snake (poisonous).
