antibodies disease

Antibodies - Monoclonal antibodies are pure, high affinity, antigen specific, proteinaceous bodies derived outside the organism from clonal cultures of hybrid cells called hybridomas. Being very specific and reproducible, antibodies are able to be conjugated to toxic d..

The first time a person gets an infection, he is likely to develop the disease because the antibody production is slow and the virus has time to multiply and spread throughout the body. The cells capable of producing antibodies persist in the body as memory cells for ..

Normally the body's immune mechanism is able to recognise its own tissues and chemicals. At times, the immunologic tolerance breaks down and the body has difficulty in discriminating between its own antigens and foreign antigens. Then the immune system attacks and destroys "Self" cells and molecul..

Immunity is said to be passive when antibodies produced in another organism are injected into a person to induce protection against diseases. Passive immunity is developed for rabies, tetanus toxin, or salmonella infection. It has the advantage of providing immediate relief. But..

Public awareness of health and hygiene is essential BCG or Bacillus-Calmette-Guerin vaccination which contains weakened Tuberculosis bacillus is injected into the system to produce antibodies that will fight the disease Cows that are milked should be immunized with tuberculin..

Active immunity develops as a result of the contact of an individual with pathogenic organisms or their products. They stimulate the body to produce antibodies in response to the antigens. The immunity thus produced is specific for a particular disease..

Immunity is said to be active when an organisms own cells produce antibodies. It develops as a result of contact with pathogenic organisms or their products. It may be acquired naturally or artificially. Active immunity is produced naturally by the attack of the disease like sma..

Active Immunity - Active immunity develops as a result of the contact of an individual with pathogenic organisms or their products. They stimulate the body to produce antibodies in response to the antigens. The immunity thus produced is specific for a particular disease. For e.g..

Vaccination and Immunisation - The principle of vaccination or immunisation is based on the property of ' memory ' of the immune system. A vaccine is always given before the occurrence of the disease. A vaccine is defined as an inoculation containing germs in dead, weakened or virulent fo..

Passive immunity is produced when antibodies formed in one human being are transferred to another non-immune individual. It may be acquired through: (1) Transmission of maternal antibodies to the foetus through the placenta. For e.g., Chicken-pox and measles (2) Injection of ant..
