a very quick replication whereby the nucleic acid (DNA or RNA) is injected into the host cell; the host cell replication machinery is hijacked and multiple copies of viruses are produced within about 25-45 minutes. Host cell bursts (lysis) spreading new viruses everywhere. This is considered a virulent reproduction.
Lysogenic:
a very slow replication where the virus DNA/RNA is inserted into host DNA and replicated as aprt of the normal host life cycle. The virus remains dormant until some signal causes it to enter the lytic cycle. Lysogenic is considered a temperate reproduction.
