Question

Define immunity, antigen, antibody and antibiotics.​
Give a note about PPIP.​

Answer 1

Immunity : It can be defined as the ability of an organism to fight against diseases and resist infections.​

Antigen : Antigens are substances that can activate an immune response by triggering the production of antibodies (glycoproteins or immunoglobulins) by the immune system.​

Antibody : Antibody (Ab) is also known as an immunoglobulin(Ig) is a protein component of the immune system. Each type of antibody is specific to a particular antigen and reacts with it to render it harmless. ​

Antibiotics : An antibiotic is a biochemical produced by a microorganism (e.g., Bacteria or fungi) which kills or block growth of other microorganisms (pathogens) by blocking their life processes without harming human cells, e.g., penicillin, streptomycin.​

PPIP : ​

• Pulse polio immunisation programme (PPIP) which forms the largest single day public health project. ​
• Pulse means a dose of a substance (here polio vaccine) especially when applied over a short period of time. ​
• It was conducted for the first time in December 1995, in an attempt to eradicate polio from our country. ​
