Differentiate between microsporogenesis and megasporogenesis. An example of artificial passive immunity is getting an injection of antisera, which is a … These antibody-containing preparations are termed antiserum. Active and passive immunity together strengthen an individual’s immune system and lower the vulnerability ratio. In active immunity, the body produces antibodies in response to infection or vaccination. Neutralizing antibodies bind directly to viral proteins, preventing the virus from infecting a cell. The adaptive response is what’s responsible for immune memory. It is a pathogen specific type of defense mechanism. Certain pathogens cause disease by secreting an exotoxin: these include tetanus, diphtheria, botulism and cholera—in addition, some infections, for example pertussis, appear to be partly toxin mediated [3,4].In tetanus, the principal toxin (termed tetanospasmin) binds to specific membrane receptors located only on pre-synaptic motor nerve cells. Some of these include age and health-related factors, such as: Additionally, there are lifestyle factors that may weaken your immune system.

Passive immunity. It could be both natural and artificial. So, for example the natural form of passive immunity is antibodies transferred in breast milk as mentioned, however an artificial form of passive immunity is the use of antidotes such as that for rabies where specific antibodies are injected into an infected individual. Passive immunity gives temporary protection by transfer of certain immune substances from resistant individuals. Examples of passive immunity. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin are transferred to non-immune persons through blood products that contain antibodies, such as in immunoglobulin therapy or antiserum therapy. Both active and passive immunity can be natural or artificial. They have the ability to recognize very particular characteristics of this viral antigen, and can tell if they have encountered this virus before. It does this through your T cells.
