Virus Cultivation- Purposes and Methods
Viruses are obligate intracellular parasites so they depend on host for their survival. They cannot be grown in non-living culture media or on agar plates alone, they must require living … Read more
Virology is a branch of natural science that deals with the biology of viruses and viral diseases, along with the biochemistry, occurrence, pathogenesis, life cycle, ecology, and evolution of viruses and virus-like particles.
