PPT-Herpesviruses & Hepatitis viruses

Prof Dr Dalya Basil Introduction The herpesvirus family contains several of the most important human viral pathogens Clinically the herpesviruses. The dis eases that these viruses cause have been described but their comparative taxonomy and host ranges require additional study All of these DNA viruses are classified in the family Herpesviridae but they belong to various taxonomic sub families DNA Enveloped .

What is a Virus?. Viruses are infectious units with diameters of about 16 nm to over 300 nm (poxviruses). Their small size makes them ultra filterable, i.e. they are not retained by bacteria-proof filters. Viruses have evolved over longtime period, and have adapted to specific organisms or their cells.
