PPT-Cell Culture and Diagnostic Virology

Since the discovery by Enders 1949 that polioviruses could be cultured in tissue cell culture has become a very useful and convenient method for isolating viruses in vitro Viral isolation in cell culture still remains the gold standard for many cultivable viruses . In sum it means cultivating and refining a thing to such an extent that its end product evokes our admiration and respect This is practically the same as Sanskriti of the Sanskrit language The term Sanskriti has been derived from the root Kri to do Virology.

Tissue culture is the general name for the removal of cells, tissues or organs from an animal or plant and their subsequent placement into artificial environment conductive to growth. This environment usually consists of a suitable glass or plastic culture vessel containing a liquid or semi-solid support medium that supplies the nutrients essential for survival and growth.
