Life cycles: The two main strategies are lytic and lysogenic. In the lytic cycle, phages replicate rapidly,
Ecology and applications: Phages shape microbial communities, contribute to horizontal gene transfer, and are explored for
History: Phages were discovered independently in 1915 by Frederick Twort in Britain and in 1917 by Félix
