PPT-General Virology 2 nd Lecture

General characters of viruses Virus particles are very small in size they are between 20500 nm nanometer in diameter For this Viruses cannot be seen by ordinary microscope but only by Electron microscope EM.

Viral isolation in cell culture still remains the "gold standard" for many cultivable viruses . Methods used in virology are various, ranging from those of molecular biology to the cell biology techniques. Each technique has its own principles and aims for which it is carried out.. Many of these methods are used, not only in virus research, in the diagnosis of virus disease of humans, animals, and plants.. Dept. of Biology, 2. nd. stage, 2016-2017. 2. nd. semester.
