Abstract:
Vaccines are the most effective and economic way of combating poultry viruses. However, the use of traditional live-attenuated poultry vaccines has problems such as antigenic differences with the currently circulating strains of viruses and the risk of reversion to virulence. In veterinary medicine, reverse genetics is applied to solve these problems by developing genotype-matched vaccines, better attenuated and effective live vaccines, broad-spectrum vaccine vectors, bivalent vaccines, and genetically tagged recombinant vaccines that facilitate the serological differentiation of vaccinated animals from infected animals. In this chapter, we discuss reverse genetics as a tool for the development of recombinant vaccines against economically devastating poultry viruses.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
