7 Lysogeny and Transduction
... Lysogeny occurs when a phage enters into a stable symbiosis with its host (Ackermann and DuBow, 1987). The host (bacterium or algal cell) and phage capable of entering into such a relationship are termed a lysogen and temperate phage, respectively. The temperate phage genome becomes integrated into ...
