    • Potential porcine endogenous retrovirus activation diagram
    Rights: The University of Waikato Te Whare Wānanga o Waikato Published 25 October 2011 Size: 31 KB Referencing Hub media

    Porcine endogenous1 retrovirus (PERV) is a retrovirus found in the DNA2 of all pigs. The virus3 is normally in an inactive proviral form, but can potentially produce mature viral particles infectious4 for other species5. PERV infection6 is a risk of pig to human transplants.

    1. endogenous: Growing or originating from within an organism.
    2. DNA: Deoxyribonucleic acid (DNA) is a molecule that contains the instructions needed for an organism to develop and function. These instructions are stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C) and thymine (T).
    3. virus: A microscopic infectious particle that can only multiply inside the cells of living organisms. They are capable of taking over the cell to produce copies of itself. They are inactive outside of a living host cell.
    4. infectious: An infection that quickly spreads.
    5. species: (Abbreviation sp. or spp.) A division used in the Linnean system of classification or taxonomy. A group of living organisms that can interbreed to produce viable offspring.
    6. infection: Invasion of the body or a species by something that could be harmful or cause a disease.
