Guys,
Many thanks for another thought provoking episode.
The discussion on Hep D reminded me of the distinction between viroids and virusoids. I think(!) that Hep D is similar to a virusoid as it is encapsulated by a helper virus, and viroids are not (coming back to the plasmid discussion in an earlier TWIV), but would appreciate your thoughts, and also whether these are recognised terms. (I also remember trying to clarify the difference in a virology textbook and could not find these terms referred to, so it may be worth covering these in the next edition of Principles of Virology if this is not already covered). Thanks again.
Rich
