PPT-Lec 7 Virology Introduction

to virology 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 ie they are not retained by bacteriaproof filters Viruses have evolved over longtime period and have adapted to specific organisms or their cells The infectious virus particles or . elseviercomlocatejcv Short Communication Comparison of the rate and size of HIV1 viral load blips with Roche COBAS TaqMan HIV1 versions 10 and 20 and implications for patient management Nigel J Garrett Vanessa Apea Achyuta Nori Ines UshiroLumb Anthon for M.Sc.

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. Viruses consist of a nucleic acid (either DNA or RNA) associated with proteins encoded by the nucleic acid. The virus may also have a lipid . bilayer. membrane (or envelope) but this is acquired from the host cell, usually by budding through a host cell membrane.
