When an animal virus integrates its genetic material into the host chromosome, it becomes a provirus. This is distinct from a prophage (term used for bacteriophages integrated into bacterial DNA). The integrated viral genome can remain dormant or be activated to produce new virus particles. Temperate virus refers to the virus type, not the integrated state, and coliphage refers to bacteriophages infecting E. coli.
