18^th International Virology Summit

General Virology and Immunization Against Viral Diseases

Viruses are smallest known infectious agents they can infect animals, plants, insects and even bacteria. A wide range of viruses are characterized according to their size and their resistance to chemical or physicals agents (alcohol,ether, etc ) and pathogenic affects. In modern period they focused on two things 1.Viruses are replicated in but they dependent on host cell machinery 2.reombinant DNA is revolution began,both bacterial and animal viruses played a critical role in this revolution. Due to this reasons they mainly focused on use of virus in cellular and molecular biology as they probe to many diverse questions in biology.Viruses exhibit strong immunological responses with both cellular and humoral immunity.Virus replication takes place in stages are adsorption , penetration, uncoating ,transcription, translation ,synthesis of nucieic acids ,assembly and the release of new virions. Many of the Antivirals were developed to treat viral infections by affecting of the viral replication stages.
