Recombinant DNA Technology: Also known as genetic engineering, it consists of several molecular techniques that are used to join (recombine) DNA fragments, thereby generating chimeric DNA molecules.
Serotype: A serologically (serum-specific) distinguishable strain of a microorganism.
Vaccine: A medicinal preparation containing harmless forms of microorganisms that cause a particular disease or several diseases. It is usually administered by injection to provide protection (immunity) against the disease(s).
Virus: A group of very minute microorganisms that can only be observed through an electron microscope. These can infect living organisms, including bacteria, plants, animals, and humans thereby causing disease.
