Secondary Infection: Virus adsorption to a cell that is already hosting a virus infection, potentially with additional interactions subsequently occurring between the virus and the same cell.

Discussion

<p>The concept of secondary infection was employed by Doermann to describe the mechanism of T-even phage class="bap-term">lysis inhibition phenomenon where an extended latent period is induced by secondary "infection" of an already phage-infected bacterium. Doermann, though, also uses the term secondary "adsorption" to describe this same inducing event.
